Definition for Mevalonic acid
From Biology Forums Dictionary
Mevalonic acid is a precursor in the biosynthetic pathway, known as the mevalonate pathway, that produces terpenes and steroids. Mevalonic acid is the primary precursor of isopentenyl pyrophosphate (IPP), that is in turn the basis for all terpenoids. Mevalonic acid is chiral and the (3R)-enantiomer is the only one that is biologically active.
