Natural Product Identification
Common Nameophirasterol
DescriptionOphirasterol belongs to the class of organic compounds known as stigmastanes and derivatives. These are sterol lipids with a structure based on the stigmastane skeleton, which consists of a cholestane moiety bearing an ethyl group at the carbon atom C24. Thus, ophirasterol is considered to be a sterol. ophirasterol is found in Topsentia ophiraphidites. ophirasterol was first documented in 2004 (PMID: 15013687). Based on a literature review very few articles have been published on Ophirasterol.
