Document Summary

A polymer is a long molecule consisting of many similar or identical building blocks linked by covalent bonds. The smaller molecules serving as the building blocks of a polymer are called monomers. A dehydration reaction occurs when monomers are connected by a reaction in which two molecules are covalently bonded to each other with a loss of a water molecule. Hydrolysis reaction occurs when the bond between monomers is broken by the addition of a water molecule. Both reactions require a hydroxyl group and a hydrogen. Nutrients for cells monosaccharides joined by a glycosidic linkage, a covalent bond formed b/w. Polysaccharides macromolecules/polymer s with a few hundred to. Storage material thousand hydrolyzed monosaccharides joined as needed to. Starch, glycogen by glycosidic linkages provide sugar for cells; building material for structures that protect cell/organism. Disaccharides and polysaccharides are formed from monosaccharides through glycosidic linkage, a covalent bond formed b/w two monosaccharides by dehydration reaction.
