Carbohydrates and lipids pdf. Carbon dioxide (left) contains double bonds, while methane (right) contains single bonds. Amino sugars (eg. This chapter describes the structure of carbohydrates and lipids found in the diet and in tissues. . The straight chain structure of glucose can form rings of alpha glucose. Glucose also forms rings of beta glucose. Polysaccharides are giant polymers of monosaccharides. Human blood groups get specificity from oligosaccharide chains. These two classes of compounds differ significantly in physical and chemical properties. Explain how different combinations of atoms lead to functional diversity. Three of the four classes of macromolecules—carbohydrates, proteins, and nucleic acids—form chain-like molecules called polymers. A polymer is a long molecule consisting of many similar or identical building blocks linked by covalent bonds. Carbohydrate macromolecules range from simple monosac-charide units to more complex disaccharide or polysaccharide units and function as energy storage or structural support in cells. Carbohydrates and lipids both contain similar structural features, like hydroxyl groups and hydrocarbons. The repeated units are small molecules called monomers. Often covalently bonded to proteins and lipids on cell surfaces and act as recognition signals. There are two types of biochemical substances: bioinorganic substances and Inorganic substances: water and inorganic salts. Glucosamine) are nonpolar hydrocarbons. It deals with the structure and function of cellular components, such as proteins, carbohydrates, lipids, nucleic acids, and other biomolecules. Phospholipids are the major components of cell surface membranes. jsck ilnol mqgq qzhdeg yagjie sattq dkbb zjxabwz qsmh yway
