Metabolite Identification
Common NameIsopropyl hexadecanoate
Description, also known as isopal or deltyl, belongs to the class of organic compounds known as fatty acid esters. These are carboxylic ester derivatives of a fatty acid. Thus, is considered to be a fatty ester lipid molecule. exists as a liquid and is considered to be practically insoluble (in water) and relatively neutral. has been detected in multiple biofluids, such as saliva and urine. Within the cell, is primarily located in the membrane (predicted from logP) and cytoplasm. exists in all eukaryotes, ranging from yeast to humans. can be biosynthesized from hexadecanoic acid. has a bland, fat, and oily taste.
