The molecule is an ergostanoid that is (22E)-ergosta-7,22-diene substituted by hydroxy groups at positions 3, 5 and 6 (the 3beta,5alpha,6beta stereoisomer). It has been isolated from the fungus, Xylaria species. It has a role as an Aspergillus metabolite. It is a 3beta-hydroxy steroid, a 5alpha-hydroxy steroid, a 6beta-hydroxy steroid and an ergostanoid.
