Myristic acid, also called tetradecanoic acid, is a common saturated fatty acid with the molecular formula CH 3(CH 2) 12COOH. A myristate is a salt or ester of myristic acid.
Myristic acid is named after the
nutmeg Myristica fragrans. Nutmeg butter is 75% trimyristin, the triglyceride of myristic acid. Besides nutmeg, myristic acid is also found in palm kernel oil, coconut oil, butter fat and is a minor component of many other animal fats. It is also found in [2 ] spermaceti, the crystallized fraction of oil from the sperm whale.
Myristic acid is also commonly added co-translationally to the penultimate, nitrogen-terminus,
glycine in receptor-associated kinases to confer the membrane localisation of the enzyme [. The myristic acid has a sufficiently high ] citation needed hydrophobicity to become incorporated into the fatty acyl core of the phospholipid bilayer of the plasma membrane of the eukaryotic cell. In this way, myristic acid acts as a lipid anchor in biomembranes. [ ] citation needed
isopropyl myristate is used in cosmetic and topical medicinal preparations where good absorption through the skin is desired [. ] citation needed
Reduction of myristic acid yields
myristyl aldehyde and myristyl alcohol.
