BIOCHEMISTRY OF THE MOLECULES OF LIFE READ CH. IN TEXT: Review the characteristics of the biological molecules - carbohydrates, proteins, and lipids. Biological Molecules Inorganic compounds 1. Usually lack carbon 2. Generally dissolve in water or dissociate to produce ions 3. Smaller in size than organic compounds 4. Usually held together by ionic bonds 5. Inorganic substances common in cells are water, oxygen, carbon dioxide, inorganic salts. Organic compounds 1. Contain carbon atoms 2. Most do not dissolve in water, those that will do not release ions 3. Large complex compounds 4. Covalent bonds 5. Include carbohydrates, proteins, lipids Carbohydrates 1. Contain carbon, hydrogen, oxygen with 1:2:1 ratio of C:H:O 2. Three types: monosaccharides, disaccharides, and polysaccharides 3. Monosaccharides (simple sugars) a. Contain 3 to 6 carbons b. Examples: glucose (6C), ribose (5C) 4. Disaccharides a. Consist of 2 monosaccharides b. Examples: sucrose, lactose 5. Polysaccharides a. Composed of many monosaccharides
