Document Summary
Lipids water-insoluble molecules that are highly soluble in organic solvents. Energy storage, components of membranes, signal-transduction pathways. Do not form polymers unlike other biomolecules. Simplest type; most commonly used as fuel. Fas very in hydrocarbon chain length important ramification when used as fuels and as components of membranes. Membranes lipids; consist of fas attached to a scaffold that also bears a charged phosphoryl group polar head, non-polar tail. Bound to carbs; important part of membranes. Function as hormones that control a variety of physiological functions. Most common steroid is cholesterol vital part of membrane. 11. 1 fatty acids are a main source of fuel. Fas are chains of h-bearing c atoms (hydrocarbons), w/ carboxylic acid groups at the end. Chains vary in length; may have one or more double bonds. Fats are good fuels b/c they are more reduced than carbs. C atoms are bonded to h atoms or other c atoms (not bonded to o atoms)
