Starch glycosidic bonds
WebbDextrin. Dextrin or dextrins are a group of low-molecular-weight polymeric carbohydrates produced by the hydrolysis of starch or glycogen. (Dextrans, although smilar in structure to dextrins, are branched glucans of microbial origin having glycosidic bonds predominantly α- (1→6)). Dextrins are mixtures of polymers of d -glucose units linked ... WebbStarch is constructed from two different polysaccharides: Amylose (10 - 30% of starch) Unbranched helix-shaped chain with 1,4 glycosidic bonds between α-glucose molecules. The helix shape enables it to be more compact and thus it is more resistant to digestion. Amylose – one of the two polysaccharides that is used to form starch (the storage ...
