Name a substance that digests glycogen.

Explanation:
Glycogen can be digested by an amylase-type enzyme, and in histology the term diastase refers to this amylase activity used to digest glycogen in tissue sections. Diastase hydrolyzes the alpha-1,4 glycosidic bonds in glycogen, removing glycogen from the sample. This is why diastase digestion is used in PAS-D staining to distinguish glycogen-containing material from other PAS-positive substances. Hyaluronidase targets hyaluronic acid, proteases break down proteins, and while amylase can act on glycogen as well, diastase is the specific enzyme referenced for glycogen digestion in this laboratory context.
