Natural Product Identification
Common Name7-keto-8-aminopelargonic acid
DescriptionPolyethylene glycol, also known as KAPA or 8-amino-7-oxononanoate, belongs to the class of organic compounds known as medium-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 4 and 12 carbon atoms. Thus, polyethylene glycol is considered to be a fatty acid lipid molecule. 7-keto-8-aminopelargonic acid is found in Ailuropoda melanoleuca and Apis cerana. Polyethylene glycol is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
