Dietary polysaccharides Metabolism

Dietary polysaccharides Metabolism
Previous Image | Next Image
Description: Dietary polysaccharides are metabolized by hydrolysis to monosaccharides.

Intracellular carbohydrate stores, as glycogen, are mobilized as phosphorylated monosaccharides by phosphorolysis.

a-Amylase in saliva cleaves bonds a(14) between the maltose units of amylopectin (or glycogen).

However, it cannot cleave a(16) glycosidic bonds in the branched polymer, and a limit dextrin accumulates unless a(16)-glucosidase (debranching enzyme) is present.
