WebIn addition, phosphorylase is an important regulatory enzyme of the pathway that responds to allosteric effectors and to phosphorylation-dephosphorylation modifications. Chapter 19 will expand on this topic. 2. Hydrolysis of α1 → 6 glycosidic bonds. This is catalyzed by α1 → 6-glucosidase, or debranching enzyme, which releases free glucose. Web3.5.1.4 Glycosides. Glycosides are composed of a glucose entity bounded to an aglycone. Glycosides are depicted by the glycone, aglycone, and the type of glycosidic bond [43, 44]. They play several imperative functions in living beings. Several floras stock substances in the form of inactive glycosides that can be triggered into active form by ...
