Alcohol sulfotransferase is an enzyme that catalyzes the sulfate conjugation of primary and secondary alcohols including many hormones, neurotransmitters, drugs, and xenobiotic compounds.^[1]^[2]

The chemical reaction is:

an alcohol + 3'-phosphoadenylyl-sulfate

\rightleftharpoons

adenosine 3',5'-bisphosphate + an organosulfate + H+

Family members

Human genes that encode alcohol sulfotransferases include:

SULT2A1
SULT2B1
SULT1C3
