The molecule is a steroid acid that is ergosta-7,24(28)-dien-21-oic acid substituted by hydroxy groups at positions 2 and 3 and a methyl group at position 5 (the 2alpha,3beta,4alpha,5alpha stereoisomer). It has been isolated from the roots of Breynia fruticosa. It has a role as a plant metabolite. It is a 3beta-hydroxy steroid, a steroid acid and a monocarboxylic acid.
