| Description | Kohamaic acid A, also known as kohamaate a, belongs to the class of organic compounds known as sesterterpenoids. These are terpenes composed of five consecutive isoprene units. (2e)-5-[(1s,4as,5r,8as)-2,5,8a-trimethyl-5-(4-methylpent-3-en-1-yl)-1,4,4a,6,7,8-hexahydronaphthalen-1-yl]-3-methylpent-2-enoic acid was first documented in 2003 (PMID: 12758147). Based on a literature review a small amount of articles have been published on Kohamaic acid A (PMID: 19127241) (PMID: 18997393). |
