Metabolite Identification

Common Name

Pantoic acid

Description

Pantoic acid (along with beta-alanine) is used to synthesize pantothenic acid (vitamin B5) in most microorganisms and plants. Pantothenic acid is a structural component of coenzyme A (CoA) which is involved in essential biological processes such as the citric acid cycle (TCA cycle) and the synthesis of carbohydrates, proteins, and fat. Pantothenic acid is found widespread in foods but especially in egg yolk, offal, fish, whole-grains, legumes, mushrooms, avocados, broccoli, and royal jelly (from bees).
