Document Summary
Fats are the major form of metabolic energy storage in humans because they provide more energy (atp) per gram than any other biomacromolecules. _the highly reduced carbons are subject to three rounds of oxidation to yield. _hydrophobic structure does not require water of hydration during storage (i. e. anhydrous lipid droplets) Micelle, and lipid bilayers as structures of lipid aggregates. _ monolayer: low concentration of lipid formed at the air-water interface. _ micelle: higher concentration of lipid and wedge-shaped lipids aggregated into a lipid globule. _ bilayer: higher concentration of lipid and non-wedge-shaped lipids. The structural characteristic of glycerophospholipids and sphingolipids (in contrast to fatty acids): Cylindrical shape due to two hydrophobic tails, which gives rise to bilayer rather than micelle more favored by wedge-shaped lipids e. g. fatty acids. _dissociated from the membrane by high salt concentrations/ changes in ph. Functions of lipid membranes: (1) energy stores (in the form of atp for chemical energy) (2) biological membranes (3) signaling molecules.
