Biological Molecules (Carbohydrates) - As Biology 0.0 / 5 ? BiologyBiological molecules, organic chemistry and biochemistryASOCR Created by: GracieCreated on: 21-05-13 21:28 Carbohydrates are ? Large complex molecules composed of long chains of monosaccharides 1 of 18 How are the OH, placed on a alpha-glucose molecule ? below, below, above, below 2 of 18 How are monosaccharides joined ? By a glycosidic bond 3 of 18 How is a disaccharide formed ? When two monosaccharides join together 4 of 18 How is a polysaccharide formed ? When more than two monosaccharides join together 5 of 18 What is starch ? A energy storage molecule in plants 6 of 18 What two alpha-glucose polysaccharides are in starch ? Amylose and Amylopectin 7 of 18 Is amylose a long unbranched chain of alpha glucose ? True 8 of 18 What properties does Amylose have ? It is compact, meaning it is a good storage as alot can be fit into a small space 9 of 18 How is Amylopectin different to Amylose ? It is branched 10 of 18 What do branches allow in a polysaccharide ? Allows enzymes to break down the molecule, to get to the glycosidic bonds easily means it can be released quickly 11 of 18 Is starch insoluble ? True 12 of 18 What is glycogen ? It is the main energy storage molecule in animals 13 of 18 Glycogen is a polysaccharide of what glucose ? Alpha 14 of 18 Is glycogen branced ? True 15 of 18 What is cellulose ? It is the major component of cell walls in plants 16 of 18 Describe the polysaccharide chain of cellulose ? Unbranched, beta glucose 17 of 18 What bonds form between the chains of cellulose ? Hydrogen 18 of 18
