Bio-Pesticides (34 suppliers)
Biopesticides are types of pesticides derived from natural materials, such as microbes, principally viruses, bacteria and fungi. The biopesticide that is registered for use in West Africa derives from a fungus that is a specific pathogen of locusts and grasshoppers. It specifically targets those insects and does not affect non-target organisms. Biological control is an important component of integrated pest and pathogen management. Endophyticmicrobes, fungi, bacteria, nematodes, viruses, plant-derived compounds are all identified & characterized for use as biocontrol agents against a wide range of pathogens and pests attacking various crops. Biopesticides developed and currently made commercially available in collaborative projects with the private sector include, Biocanii, based on a strain of the fungus Verticillium lecanii for the control of whiteflies & thrips on flowers, beans, avocado, cotton, onion, citrus, asparagus, papaya, tomatoes & other horticultural crops, Biorhizium, based on two strains of the fungus Metarhizium anisopliae for the control of various insects, such as spittlebugs in pastures, Biovirus, based on a baculovirus & used for the control of cassava hornworm & Ecoswing®,.a biofungicide formulated from extracts of the plant swinglia (Swinglia glutinosa).

Bioactive Peptides (25 suppliers)
Peptides are short proteins formed by a chain consisting of 50 or less amino acids The term bioactive peptides is used to identify molecules of peptidic nature or origin which display a biological behaviour or activity which can be developed at the industrial level for pharmaceutical, diagnostic, chemical and agro-food applications. In this way it is possible to obtain modified peptides with superior properties for therapeutic applications. The great advantage of using modified peptides instead of classical peptidomimetics is a very high bioavailability, a long lasting activity in vivo, and limited toxicity. Beside this, the costs for setting-up the synthetic strategy are quite low, when compared to those of setting-up stereo-specific synthetic routs. Examples include various forms of peptides such as galanin, peptide YY, neuropeptide Y, secretin, cholecystokinin, insulin-like peptides, LEAP-2, and a number of others .

Biocatalysis (5 suppliers)
Biocatalysis, bioprocessing & biotransformations involve the use of enzymes (often immobilized) and/or microorganisms (often immobilized whole cells) to perform chemical conversions. The enzymes are not reagents, but rather catalysis (biocatalysts performing highly focused biotransformations, but not consumed in the reaction). However, like all catalysts, there are stability issues that must be addressed for the biocatalytic process for it to be commercially sensible. Many synthetic organic chemists would like enzymes to be simple off-the-shelf catalysts that can be used painlessly to perform desired organic transformations. Applied biotransformations & biocatalysis are becoming more and more prevalent in the synthesis of fine chemicals & pharmaceuticals, as an efficient replacement for certain key reaction steps. Most important are pharmaceutical applications. There, the use of enzymes to catalyze stereospecific & regiospecific organic reactions is incredibly valuable due to potentially high degrees of selectivity and yield effected by enzymes. Another tremendous benefit is that the formation of side products can be significantly lessened.
Biocatalysts (12 suppliers)
The term biocatalyst can refer to enzymes in various forms which are pure enzymes crude enzymes, immobilised enzymes, whole cell, immobilised whole cell, catalytic antibodies, designer enzymes and recently cross-linked enzyme crystals. The employment of enzymes and whole cells have been important for many industries especially for centuries in the food & drink businesses where the production of wine, beer & cheese is dependent on the effects of the microorganisms. Biocatalysis has wide applications to produce fine chemicals, especially for the pharmaceutical industry. The biggest advance in biotransformation operation has to be recombinant DNA technology. Not only is it possible to over express particular genes but it is also possible to express them in another organism, or to create unique catalysts. For example, a plasmid containing genes over expressing trehalase has been inserted into Escherichia coli. The enzyme accumulated in the periplasm of the Escherichia coli and this made it easy to extract it by osmotic shock . It is now anticipated that within a few years more than half the world's enzymes will be produced commercially using recombinant DNA technology.

Biochemical Lipids (18 suppliers)
The term lipid comprises a diverse range of molecules and to some extent is a catchall for relatively water-insoluble or nonpolar compounds of biological origin, including waxes, fatty acids, fatty-acid derived phospholipids, sphingolipids, glycolipids and terpenoids (eg. retinoids and steroids). Most lipids have some polar character in addition to being largely nonpolar. Generally, the bulk of their structure is nonpolar or hydrophobic ('water-fearing'), meaning that it does not interact well with polar solvents like water. Another part of their structure is polar or hydrophilic ('water-loving') and will tend to associate with polar solvents like water. This makes them amphiphilic molecules (having both hydrophobic and hydrophilic portions).For microbiology and food research sphingosines, ceramides, gangliosides, phosphatidyl inositol phosphates were used.
Biochemical Microparticles (Coated / Treated Surface) (14 suppliers)
Microparticles are particles between 0.1 and 100 ?m in size. Commercially available microparticles include those made of glass, latex, polystyrene, various metals (carbon, silver, copper, etc.), and various magnetic materials. Microparticles have been found to have widespread applications in medicine, biochemistry, colloid chemistry, and aerosol research. Uses include chromatographic separation media, supports for immobilized enzymes, and spacers in liquid crystal displays Monodisperse melamine resin particles are a new class of polymer particles with excellent physical and chemical properties. Polystyrene nano- and microspheres particles are typically used for calibration purposes and immunoassays (latex agglutination test, FACS). Many of the tests are based on non-covalent binding of specific antibodies, antigens or cells to the hydrophobic particle surface. Covalent attachment of proteins to surface modified particles is possible .
Biochemical Monoglycerides (5 suppliers)
Monoglycerides are amphiphatic neutral lipid molecules in which a hydrophobic fatty acid is attached via an ester bond. Despite their relatively simple chemical structure, monoglycerides can form various phases found in membrane phospholipid/water systems, namely the coagel or lamellar crystalline (Lc) phase, the lamellar gel (L) phase, the lamellar liquid-crystalline (L) phase, bicontinuous cubic phases of different symmetry, the inverted hexagonal (HII) phase, and the inverted micellar (L2) phase. The lipid organization in monoglyceride-water systems is strongly dependent on the chemical structure of the monoglyceride and on environmental conditions such as temperature, water, and salt content.The ability of monoglyceride/water systems to form different structures offers many interesting opportunities for studies on membrane structure and function, as well as for industrial applications. Being a natural emulsifier, monoglycerides are widely used in the food industry.. During fat digestion the enzymatic hydrolysis of triglycerides leads to accumulation of a large amount of monoglycerides, which may result in formation of a bicontinuous cubic phase. .
Biochemical Monosaccharides (11 suppliers)
The simplest type of carbohydrate is a monosaccharide, which among other properties contains carbon, hydrogen, and oxygen, mostly in a ratio of 1:2:1 . Glucose, one of the most important carbohydrates, is an example of a monosaccharide. So is fructose, the sugar that gives fruits their sweet taste. . Monosaccharides can be grouped into aldoses (having an aldehyde group at the end of the chain, e. g. glucose) and ketoses (having a keto group in their chain; e. g. fructose). Both aldoses and ketoses occur in an equilibrium between the open-chain forms and (starting with chain lengths of C4) cyclic forms. These are generated by bond formation between one of the hydroxyl groups of the sugar chain with the carbon of the aldehyde or keto group to form a hemiacetal bond. This leads to saturated five-membered (in furanoses) or six-membered (in pyranoses) heterocyclic rings containing one O as heteroatom
Biochemical Mucopolysaccharides (7 suppliers)
The mucopolysaccharides are a group of inherited lysosomal storage disorders of connective tissue each with distinctive phenotypes and a progressive course due to severe deficiency of an enzyme which usually catalyzes a step in the degradation of glycosaminoglycans. In general, excessive quantities of glycosaminoglycans are excreted in urine which can be analyzed. Specific enzyme analyses must be run for a definitive diagnosis. Mucopolysaccharides analysis is usually performed on urine
Biochemical Neurochemicals (22 suppliers)
A neurochemical is an organic molecule that participates in neural activity. This term is often used to refer to neurotransmitters and other molecules such as neuro-active drugs that influence neuron function Norepinephrine, dopamine, and serotonin were examples of neurochemicals. o GABA is an example of an inhibitory neurotransmitter. o Dopamine is another example of a neurotransmitter. It plays a key role in the functioning of the limbic system, which is involved in emotional function and control. o Serotonin plays a regulatory role in mood, sleep, and other areas. o Acetylcholine assists motor function.
Biochemical Neurotransmitters (8 suppliers)
Neurotransmitters - biochemicals that send nerve impulses from one region of the brain to another - cause a person to feel a given emotionThe brain is a chemical factory that constantly produces neurotransmitters throughout our lives. The raw materials are amino acids, vitamins, minerals, and other nutrients. In a healthy body, neurotransmitter levels are constantly monitored and kept in check. However, the balance of these biochemicals is subject to many forms of disruption. Because neurotransmitters are comprised of several amino acid building blocks that are supplied through proper nutrition, poor diet-or poor digestion-can rapidly deplete some neurotransmitters, thereby increasing the level of others. In addition, medications as well as illicit drugs may decrease stores, often, resulting in severely elevated neurotransmitter levels which are often evident in urine. . The hormones produced Chemical neurotransmitters relay, amplify and modulate signals between a neuron and another cell. autonomic functions

Biochemical Solvents (23 suppliers)
A solvent is a liquid that dissolves a solid, liquid, or gaseous solute, resulting in a solution.The most common solvent in everyday life is water. Most other commonly-used solvents are organic (carbon-containing) chemicals. These are called organic solvents. Biochemicals can be effective replacements for petrochemicals, but their use tends to be more knowledge intensive than the use of petrochemical solvents. Manufacturers must learn how to apply a biochemical cleaning solvent in each individual cleaning situation. Implementation of alternative cleaning methods requires that workers be trained in new cleaning techniques and educated in the handling of unfamiliar solvents
