Name(R)-Pantothenic acid
SpeciesSaccharomyces cerevisiae
StrainBaker's yeast
DescriptionR-Pantothenate (vitamin B5) is the amide between (R)-pantoate and beta-alanine. It is a precursor for the synthesis of the 4'-phosphopantetheine moiety of coenzyme A (CoA) and acyl carrier protein in bacteria and eukaryotes. Only plants and microorganisms (including some eukaryotic microbes, such as S. cerevisiae) can synthesize pantothenate de novo - animals require a dietary supplement.
