Batyl alcohol is an organic compound with the formula HOCH₂CH(OH)CH₂OC₁₈H₃₇. 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:

HOCH₂CH(OH)CH₂OC₁₈H₃₇ + 1.5 O₂ → HOCH₂CH(OH)CH₂OH + HO₂CHC₁₇H₃₅ + H₂O

Batyl alcohol and related glycyl ethers are also susceptible to dehydrogenation catalyzed unsaturases to give the vinyl ethers called plasmalogens:^[3]

HOCH₂CH(OH)CH₂OC₁₈H₃₇ + [O] → HOCH₂CH(OH)CH₂OCH=CHC₁₆H₃₅ + H₂O
