Abstract

The present invention provides a lipase substrate of the general formula: ##STR1## wherein A is an alkalene or alkenylene radical containing up to 16 carbon atoms, R and R.sub.1, which can be the same or different, each signify an alkyl, alkenyl or acyl radical containing up to 20 carbon atoms or an optionally alkyl-substituted aryl or aralkyl radical containing up to 8 carbon atoms in the alkyl moiety and wherein one of R and R.sub.1 can also be a hydrogen atom, X is the residue of an aromatic hydroxy or thiol compound, and each Y and Z, independently from each other, is --S-- or --O--, Z also --CH.sub.2 --. The present invention also provides a process and a reagent for the optical determination of lipase.
