Vitamins serve as a coenzyme. • Ascorbic Acid The coenzyme forms are sometimes produced in a cleaner and purer way than their isolated alternatives (e.g. -Biotin, like lipoic acid, is converted to its coenzyme form (called biotinyllysine or biocytin) by formation of a covalent amide bond to the nitrogen atom of a lysine residue. Vitamins can serve as precursors to many organic cofactors (e.g., vitamins B 1, B 2, B 6, B 12, niacin, folic acid) or as coenzymes themselves (e.g., vitamin C). • Pantothenic Acid (B5) -Vitamin C differs is a cofactor for certain hydroxylase enzymes, and plays a direct role in chemical reactions in the cell. It helps certain cells carry out essential functions, such as the regulation of cell growth and death. Lecturer/Researcher in Biochemistry. Higher blood levels of vitamin C and coenzyme Q10 have been associated with decreased risk of cardiovascular death. Coenzymes are non-protein organic molecules that are mostly derivatives of vitamins soluble in water by phosphorylation; they bind apoenzyme to proteins to produce an active holoenzyme. Chess tutor. Coenzyme Definition . • Cobalamin (B12) The coenzyme forms of vitamin B 12 are methylcobalamin (Figure 2) and deoxyadenosylcobalamin. maintaining some metal cofactors in reduced state. -During the liver alcohol dehydrogenase LADH reaction, the hydrogens from ethanol are transferred to NAD to produce acetaldehyde and NADH. 1. If you have any questions, ask your doctor or pharmacist.. Question 14 of 40 What vitamin acts as a coenzyme in cell respiration and is important in alcohol fermentation?
