Document Summary
Biological molecules soluble in organic solvents but only sparingly soluble in water: not polymers, aggregation e. g. bilayers (membranes, greatest structural variation of major biomolecules. Intercellular: amphiphilic/amphipathic, usually esterified form in nature. Saturated and unsaturated: usually even number of carbon atoms. Increased fluidity: constitute ~90% of dietary lipid, major form of metabolic energy storage in humans. 2-3 month energy supply versus <1 day for glycogen. Thermal insulation: not components of biological membranes. Soluble in lipid bilayer e. g. coenzyme q/ ubiquinone. Biological membranes: organized assemblies of lipids, proteins and small amounts of carbohydrates, regulate composition of intracellular medium by controlling flow of nutrients, waste products, ions, etc. in and out of cell. Stable purification: manipulate internal content, delivery fusion with plasma membrane. Peripheral or extrinsic proteins and integral or intrinsic proteins: catalysis of chemical reactions (electron transport and oxidative. Signaling (hormone receptors e. g. glucagon or insulin)
