Natural Product Identification
Common Nameximenic acid
Description(17Z)-hexacosenoic acid, also known as C26:1N-9 or 17cis-hexacosenoate, belongs to the class of organic compounds known as very long-chain fatty acids. ximenic acid is found in Tropaeolum speciosum and Ximenia americana. ximenic acid was first documented in 1997 (PMID: 9074810). These are fatty acids with an aliphatic tail that contains at least 22 carbon atoms (17Z)-hexacosenoic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (PMID: 9622383).
