01.11.2008 BI 212 Lab #1 Questions III. Chemical Bonding Models 3. O H H 4. Covalent bonds are formed. This is shown by single and double lines, double lines represent double bonding. O H H 5. H H H C H H C H H H 6. Carbon can bond four times, oxygen can bond twice, and hydrogen bonds once. V. Carbohydrates 2. Glucose, C 6 H 12 O 6 , ratio is 1:2:1. Monosaccharides compose most of the major nutrients found in a cell. 3. Their formulas are C 6 H 12 O 6 the structure differs. These two compounds are hexose sugars. 4. The reaction is a dehydration reaction, creating a glycosidic linkage. Water is also produced in addition to sucrose. 5. Dehydration reactions form polysaccharides. Polysaccharides store sugar for use by cells. 6. Consumed. Hydrolysis occurs. VI. Lipids 1. Fats are large molecules assembled by smaller molecules by dehydration reactions, also triglycerides. Fats store energy, and add cushioning to organs. Fatty acid. Lipids consist of H, C, and O. Double bonding in
