Skin Care - Definition of Coenzymes

A coenzyme is a small molecule (not a protein but sometimes a vitamin) essential for the activity of some enzymes.

In biochemistry, it is an organic non-protein molecule, frequently a phosphorylated derivative of a water soluble vitamin, that binds with the protein molecule (apoenzyme) to form the active enzyme (holoenzyme).

Coenzymes are necessary for the conversion of linoleic acid into GLA, required for epidermal synthesis of PG-1 and PG-2 (prostaglandins), necessary for smooth skin texture.
