Batyl alcohol is an organic compound with the formula HOCH
2CH(OH)CH
2OC
18H
37. It is a colorless solid. Batyl alcohol is a monoether formed by condensation of stearyl alcohol with one of the two primary alcohol sites of glycerol. Together with S-selachyl alcohol and S-chimyl alcohol, S-batyl alcohol is a component of some lipid membranes.[1]
Occurrence and metabolism
It is found in the liver of the shark Centrophorus squamosus.[2] The name batyl is derived from a classification of rays, order Batoidea. Like other glyceryl ethers, those derived from batyl alcohol are not saponifiable.[3]
Batyl alcohol and related glycyl ethers are susceptible to oxidation catalyzed by glyceryl-ether monooxygenases. The net oxidation gives glycerol and the carboxylic acid:
- HOCH
2CH(OH)CH
2OC
18H
37 + 1.5 O
2 → HOCH
2CH(OH)CH
2OH + HO
2CHC
17H
35 + H
2O
Batyl alcohol and related glycyl ethers are also susceptible to dehydrogenation catalyzed unsaturases to give the vinyl ethers called plasmalogens:[3]
- HOCH
2CH(OH)CH
2OC
18H
37 + [O] → HOCH
2CH(OH)CH
2OCH=CHC
16H
35 + H
2O
