Necessary in the body, but not diet. Too much in the blood can increase risk of cvd. Roles of cholesterol: synthesis of vitamin d from the sun, synthesis of testosterone and estrogen. Contain an acid group at the end of the chain. Short milk, do not harden in fridge. Medium coconut oil, solid when cold and liquid at room temp. Unsaturated fatty acids have 1 or more double bonds. Affects process in body and effect on health. The bond closest to the end of the fatty acid affects how your body uses fat. Cis = hydrogen molecules on the same side.

Turns a liquid fat into a solid fat. Trans fats are naturally found in milk, meats, cheese.
