Identification
Name: 4-Phosphopantothenoylcysteine
Description:4-Phosphopantothenoylcysteine (PPC) is an intermediate in the biosynthetic machinery (pathway) that converts pantothenate (vitamin B5) into coenzyme A (CoA). The enzyme Phosphopantothenoylcysteine decarboxylase catalyzes the decarboxylation of PPC to 4'-phosphopantetheine. Coenzyme A is the principal acyl carrier and is required for many synthetic and degradative reactions in intermediary metabolism, and is an essential cofactor in all living systems.
