For the specific determination of pancreatic alpha -amylase in the presence of salivary alpha -amylase in body fluids by reaction with a system for detecting alpha -amylase with the addition of an inhibitor for salivary alpha -amylase, the substrate used is a compound with the general formula I n<IMAGE>n in which R1 is a straight-chain or branched alkyl or alkoyl group with 1 to 6 C atoms, a cycloalkyl group or cycloalkoyl group with 3 to 6 C atoms, a benzoyl, benzyl or phenyl radical, in each case optionally with hydrophilic substituents, and R2 is a hydrogen atom, or in which R1 and R2 together form a methylene bridge whose H atoms can, independently of one another, each be replaced by an alkyl group with 1 to 5 C atoms or a phenyl group, Gluc is a glucose molecule, n is an integer from 1 to 3, and X is a radical which can be determined optically. |
