Polysaccharides are polymers of sugars, where hundreds or thousands of monosaccharides are joined together by glycosidic linkages.
A glycosidic linkage is a covalent bond that is formed between two monosaccharides by a dehydration reaction — the removal of a water molecule (H + OH).
Polysaccharides are used for:
1. Storage
In plant cells, excess made by photosynthesis is turned into starch.
In animal cells, excess eaten is stored as
