Document Summary
A coiled coil: is where one helix is wrapped around another helix to get a stronger structur. Keratin has two right handed helicies wrapped in a left handed fashion. Collegian has two left handed helicies wrapped in a right handed fashion. Has two hydroxyl groups that put it through post modification. Two histamines pinch together an oxygen and a heme group. Tttt tttt rttt rrrr r(o2)r(o2)r(o2)r(o2) The fetus has fetal hemoglobin which has a slightly different sequence therefore, it has a lower a inhibitor so it can take more oxygen. When the ph drops, hemoglobin"s affinity for oxygen drops. When the co2 reacts with a water molecule, it produces a proton and a molecule of bicarbonate muscles can produce more co2 in a soluble form and increases ph in red blood cells. Lactic acid decreases the ph in muscles in anaerobic respiration. The valine buries itself in the hydrophobic pocket.
