Metabolite Identification
Common NameArachidyl alcohol
DescriptionArachidyl alcohol, also known as 1-eicosanol or eicosyl alcohol, belongs to the class of organic compounds known as long-chain fatty alcohols. These are fatty alcohols that have an aliphatic tail of 13 to 21 carbon atoms. Thus, arachidyl alcohol is considered to be a fatty alcohol lipid molecule. Arachidyl alcohol is a very hydrophobic molecule, practically insoluble in water and relatively neutral.

Catalyzes the reduction of saturated fatty acyl-CoA with chain length C16 or C18 to fatty alcohols.
Gene Name:
FAR1
Uniprot ID:
Q8WVX9
Molecular weight:
59356.25
General function:
Involved in catalytic activity
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.
Gene Name:
FAR2
Uniprot ID:
Q96K12
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).
Gene Name:
AWAT1
Uniprot ID:
Q58HT5
Molecular weight:
37758.815
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.
