Shikimic Acid

Shikimic acid is a cyclohexenecarboxylic acid that is cyclohex-1-ene-1-carboxylic acid substituted by hydroxy groups at positions 3, 4 and 5 (the 3R,4S,5R stereoisomer). It is an intermediate metabolite in plants and microorganisms. It has a role as a Saccharomyces cerevisiae metabolite, a plant metabolite and an Escherichia coli metabolite. It is a cyclohexenecarboxylic acid, a hydroxy monocarboxylic acid and an alpha,beta-unsaturated monocarboxylic acid. It is a conjugate acid of a shikimate. — ChEBI
