LIBRARY Starch. Computer-generated molecular model of starch, a type of carbohydrate. Carbon atoms are grey, oxygen is red, and hydrogen is white. Poly- saccharides such as starch consist of various proportions of glucose polymers, amylose and amyl- opectin joined in a chain. Starch occurs widely in plants as a store of carbohydrate and so is a major source of energy for animals. Digestion of starch ultimately yields glucose sugar.
