Document Summary
Molarity- mole concentration of substance in g. Molarity- molecular weight in grams/liter; osmols=moles x #of particles; 1m x 2 particles = 2 osmols. Osmolarity- solute concentration per liter of solution; unit- osmols. Osmolarity depends on number of particles; 1 m=58g/liter. Structual: cellulose-> cell wall of plant cells, chitin->shell of crabs. Don"t need to know classification; only some names of aas. Smallest protein: 3 aa; trh- thyrotropin release hormone. Primary structure: # and sequence of aa. Secondary structure: chain is folded and has hydrogen bonds. Tertiary structure: highly folded, complex, many types of bonds [covalent, ionic, etc], Lipids: c h o; oxygen is low ratio. High energy released in oxidation ->36 atp. Saturated- straight chain; no double bond; solid at room temperature; animal fats. Arteriosclerosis- hardening of arteries; no elasticity; may result in ischemia. Unsaturated- double bonds; bent at double bond; liquid at room temperature; plant fats. Phospholipids- plasma membranes made of phosphate; glycogen[hydrophilic] with two fatty acids [hydrophobic]
