BIOL 3210 Lecture Notes - Lecture 16: Integral Membrane Protein, Dehydration Reaction, Sodium-Potassium Alloy
Document Summary
Lipids organic molecules that are characterized by low solubility in water, hydrophobic, don"t conform to a particular structural formula. Insulation from the environment: important in other animals, like blubber. Water repellant like a waxy leaf. Buoyancy control: it"s a thing, she doesn"t know. Cofactors for enzymes signaling molecules, pigments, antioxidants. Arachidonic acid can be converted enzymatically to prostaglandins, thromboxanes, leukotrienes. Hibernation allow inactivation for a long time. Adiposites made into adipose tissue: clumped together, intracellular, adipose tissues clump and. Sorts and increases the concentrations of reactants to facilitate desirable reactions. Made possible by the weird characteristics of amphipathic (both hydrophobic and hydrophilic) lipids. Glycerol glycerides are the structural base of lipids. Fatty acids (acid and then a lot of fatty hydrocarbons: majority have an even number of carbons (14-20 is a normal length) Three fatty acids on the carboxyl ends dehydration reaction: makes and ester bond.
