Chemical Information

FooDB Name

alpha-Lipoic acid

Description

Lipoate, also known as lipoic acid or 6,8-thioctate, belongs to lipoic acids and derivatives class of compounds. Those are compounds containing a lipoic acid moiety (or a derivative thereof), which consists of a pentanoic acid (or derivative) attached to the C3 carbon atom of a 1,2-dithiolane ring. Lipoate is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Lipoate can be synthesized from octanoic acid. Lipoate can also be synthesized into lipoamide and lipoyl-AMP. Lipoate can be found in broccoli and spinach, which makes lipoate a potential biomarker for the consumption of these food products. Lipoate may be a unique E.coli metabolite. Lipoate is a non-carcinogenic (not listed by IARC) potentially toxic compound.
