Document Summary

Research projects: 3 resources, 2 = academic/scholarly journals, bibliography. Sodium: hydrogen, magnesium* (least abundant, carbon, nitrogen, oxygen, phosphorous, chlorine. Bonds important in biology: covalent, polar: h-o (oxygen electronegative - hydrogen bonding, nonpolar: h-h. Explains protein folding: weak interaction (beating vinegar/water can destroy interaction, van der waals interaction, nonpolar molecules are also attracted to each other via relatively weak attractions called van der waals forces (transient dipoles, weak. Strength: van der waals < hydrophobic < ionic*/hydrogen < covalent. Ionic = the one occurring on the inside of proteins (not the same as salt crystal) Chemical reactions: rule: must balance, *matter is neither created nor destroyed. Molarity: atomic mass = atomic weight = molecular weight, 1 mol = amount of substance in grams whose weight = molecular weight, 1m solution is 1 mole of compound dissolved in water to make on liter.
