Starch function and structure
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 ...
