Define.
- Rancidity: The unpleasant Odour, Smell and taste developed by the oils and fats due to denaturation and Oxidation.
- Biomolecule: Organic Compounds as an essential component of living Organisms.
- Decarboxylation: Removal of CO2 from Carboxylic Group and conversion of Amino Acid to corresponding amines.
- Protein Denaturation: Disruption of original structure of protein and loss of its biological activities due to change in pH, heat, organic Solvent etc.
- Waxes: Waxes are water insoluble solid esters and higher fatty acids with long chain alcohol.
- Mutaorotation: Gradual change in specific rotation of optically active compounds in aqueous solution.
- Transamination: This reaction involves the transfer of an amino group from a donor amino acid to an acceptor a-keto acid to yield the a-ketoacid of the donor amino acid and the amino acid of the original a-keto acid.
- Catabolism: Process of decomposition or breakdown of complex substances like lipid, Carbohydrates, Proteins for release of energy.
- Biomolecule: An organic compound normally present as an essential component of living organism.
- Nucleoside: A compound composed of a purine or pyrimidine base covalently linked to a pentose sugar either Ribose or deoxyribose.
- Peptide: Amino acid units are joined together through carboxylic acid(-COOH) group or amino group(-NH2) to produce the primary structure of protein.
- Gums: Any class of colloidal, water soluble substance(Chemically hemicellulose) that is exuded by or extracted from plant, gluey when wet and hardened on drying, consists of many kinds of monosaccharide units.
- Lignins: Lignin, a cell wall strengthening material, is a C6.C3 polymer. It is more abundant in wood, corky tissues and straw. Lignin imparts resistance to degradation by water and microorganisms.
- Waxes: Waxes are water insoluble substances present on the surface of plant and animal bodies. They include a variety of compounds such as hydrocarbons, alcohols, ketones, and carboxylic acids and most importantly the esters of long chain monohydroxy alcohols (24 to 28 C) with fatty acids (20 to 24 C).
- Monosaccharides: these are the simple sugar which cannot be hydrolyzed in to simple product with general formula (CH2O)n.
- Transamination: This reaction involves the transfer of an amino group from a donor amino acid to an acceptor a-keto acid to yield the a-ketoacid of the donor amino acid and the amino acid of the original a-keto acid.
