Studies on Alginase

Abstract
Alginase obtained from liver of abalone, Haliotis discus hannai, was found to hydrolyze alginic acid to a new unsaturated diuronide, which showed ultraviolet absorption peak at 232 mµ. Some of the properties of this compound were found similar to those of the known unsaturated uronides derived from hyaluronic acid, pectin or chondroitin sulfate.
