eed a water molecule to make the hydroxyl group and the hydrogen that were there before cule consisting of monomers linked together by covalent bonds eaction, when two monomers or polymers bond, they make a water molecule which goes away Monomer - building blocks of polymers AP Biology Name _Adeesh Jain_____________ Chapter 5 Guided Reading Assignment Label the diagram below – identify a monomer, polymer, condensation reaction, and hydrolysis. 1. What are the three hexose monosaccharides? The three hexose monosaccharides are glucose, galactose, and fructose. 2. What is a glycosidic linkage and what do the numbers 1-4 and 1-2 relate to? A glycosidic linkage is a covalent bond which bonds two monosaccharides making a disaccharide. In this linkage, the condensation reaction takes place making water and the two monosaccharides have their carbon molecules bonded with an oxygen molecule. The numbers 1-4 and 1-2 are what carbon bonds with the other carbon. For example, in maltose, glucose’s carbon 1 has a glycosidic linkage with the other glucose’s carbon 4, making 1-4. In sucrose, carbon 1 on glucose bonds with carbon 2 in fructose making the 1-2. 3. Compare and contrast the two storage polysaccharides. The two storage polysaccharides are starch and glycogen. Plants use starch, whereas animals, like us, use glycogen. Starch is stored as granules in plastids, like chloroplasts. Animals store glycogen in the liver and muscles. Starch is simpler, having one form that is unbranched (amylase) and branched (amylopectin). Glycogen is branched several times making it complicated. Plant or animal, both starch and glycogen is stored and when needed, hydrolysis takes place breaking the polysaccharide into monomers which the plant or animal can use. 4. Compare and contrast the two structural polysaccharides.
