BIOL 1201 Lecture : BIOL 1201 Lecture 1
Document Summary
Pre-class: moodle: quizzes 3&4b open after class closes thursday. Acyl chains: require lower temp to be solid. Carb storage in animals: as glycogen: tail avoids water. 1g of glycogen stored with 2-5 g of water. Disadvantage: not as rapidly mobilized as carbs. Lipids only metabolized in the mitochondria in presence of o2. Cq: glucose: hydroxyl groups (polar) dissolve in water. Cq: hump of a camel filled with lipid. Up to 20% body mass is fat when food plentiful. Nucleic acids: nitrogenous heterocyclic bases, pentose sugar: (carb, phosphoric acid: Proteins vary in terms of # of aa & sequence of the different kinds of aa. 5. 15b: aa, the monomers, 20 kinds, central carbon. Carboxyl group: characteristic of an acid what makes aa an acid: hydrogen: simplest r group, r group! Figure 5. 16a: 20 aa of proteins: nonpolar. Nonpolar- no partial charges on the r group.
