| coenzyme q10 | <biochemistry> A substance that assists in the oxidation of nutrients within cells to create energy. It is also highly efficient at protecting internal and external cell membranes against oxidation and is sometimes proposed as a complementary therapy to combat AIDS-related conditions. (09 Oct 1997) |
| coenzyme R | <biochemistry> A prosthetic group for carboxylase enzymes. Important in fatty acid biosynthesis and catabolism and has found widespread use as a covalent label for macromolecules which may then be detected by high affinity binding of labelled avidin or streptavidin. Essential growth factor for many cells. (18 Nov 1997) |
