Metabolite Identification
Common Name1-Hexadecanol
DescriptionCetyl alcohol, also known as 1-hexadecanol and palmityl alcohol, is a solid organic compound and a member of the alcohol class of compounds. Its chemical formula is CH3(CH2)15OH. At room temperature, cetyl alcohol takes the form of a waxy white solid or flakes. It belongs to the group of fatty alcohols. With the demise of commercial whaling, cetyl alcohol is no longer primarily produced from whale oil, but instead either as an end-product of the petroleum industry, or produced from vegetable oils such as palm oil and coconut oil. Production of cetyl alcohol from palm oil gives rise to one of its alternative names, palmityl alcohol.

General function:

Specific function:
Catalyzes the reduction of fatty acyl-CoA to fatty alcohols. The preferred substrates are C16, C18, C18:1 and C18:2 but low activity can be observed with C10-C14 substrates.

Molecular weight:
59437.92
General function:
Involved in transferase activity, transferring acyl groups other than amino-acyl groups
Specific function:
Acyltransferase that predominantly esterify long chain (wax) alcohols with acyl-CoA-derived fatty acids to produce wax esters. Wax esters are enriched in sebum, suggesting that it plays a central role in lipid metabolism in skin. Has a preference for arachidyl alcohol as well as decyl alcohol, demonstrating its relatively poor activity using saturated long chain alcohols (C16, C18, and C20).

General function:
Involved in transferase activity, transferring acyl groups other than amino-acyl groups
Specific function:
Acyltransferase that predominantly esterify long chain (wax) alcohols with acyl-CoA-derived fatty acids to produce wax esters. Wax esters are enriched in sebum, suggesting that it plays a central role in lipid metabolism in skin. Has no activity using decyl alcohol and significantly prefers the C16 and C18 alcohols. May also have 2-acylglycerol O-acyltransferase (MGAT) and acyl-CoA:retinol acyltransferase (ARAT) activities, to catalyze the synthesis of diacylglycerols and retinyl esters; however this activity is unclear in vivo.
