(a) Label the acetal in salicin, a naturally occurring pain reliever isolated from the bark of the willow tree. (b) How many 1° OH groups does salicin contain?

Aspirin is an anti-inflammatory agent because it inhibits the conversion of arachidonic acid to prostaglandins by the transfer of its acetyl group (CH3CO –) to an OH group at the active site of an enzyme (Section 19.6). This reaction, called transesterification, results in the conversion of one ester to another by a nucleophilic acyl substitution reaction. Draw a stepwise mechanism for the given transesterification.
