Thesis(Ph.D.)- University of Birmingham, Department of Chemistry.
Candida antarctica: lipase B (CALB) is the most widely studied enzyme, due to its high selectivity and catalytic activity in organic and polymer synthesis. To avoid organometallic catalysts in the synthesis of biodegradable polyesters, the enzymatic ring-opening polymerization of cyclic esters can be carried out with CALB as a by: The above-mentioned biological tools, together with traditional screen73,74 are now available to the chemist to aid in the development of new enzymes for chemical by:
In chemistry, an ester is a chemical compound derived from an acid (organic or inorganic) in which at least one –OH (hydroxyl) group is replaced by an –O–alkyl group. Usually, esters are derived from a carboxylic acid and an alcohol. Glycerides, which are fatty acid esters of glycerol, are important esters in biology, being one of the main classes of lipids, and making up the bulk of. The structures of new compounds synthesized were characterized by elemental analysis and spectral data, and their in vitro antibacterial and anticancer activities against the three cancer cell.
Ester, any of a class of organic compounds that react with water to produce alcohols and organic or inorganic acids. Esters derived from carboxylic acids are the most common.
