Abstract

An aromatic substituted glycoside is disclosed of the formula ##STR1## wherein the configuration of the substituted --OR on the anomeric carbon is alpha, n is an integer of 0 or 1, and R is a substituted aromatic radical selected from the group ##STR2## where R.sub.1 through R.sub.6 are independently halogen, NO.sub.2, SO.sub.3 H, ##STR3## where R.sub.7 is lower alkyl; and includes its stereoisomers, optical isomers and geometric isomers and mixtures of the foregoing isomers. These substrates are useful as direct substrates for alpha-amylases. A process for the preparation of the substrates and related substances is also described.
