FooDB Name

Octacosanoic acid

Description

Octacosanoic acid is a very-long-chain fatty acid found in human brain and visceral organs (PMID: 2474624) Octacosanoic acid is a higher aliphatic primary acids purified from sugar-cane (Saccharum officinarum L.) wax that has been shown to inhibit platelet aggregation induced ex vivo by addition of agonists to platelet-rich plasma (PRP) of rats, guinea pigs, and healthy human volunteers. (PMID: 5099499) Octacosanoic acid is formed from octacosanol via beta-oxidation. (PMID: 15847942) [HMDB].
