Lipids
2003-2004
Large biomolecules that are made mostly
of carbon and hydrogen with a small
amount of oxygen (sometimes
Phosphorous).

Lipids
Function:Stores energy
very concentrated (pure)2 times as much as carbohydrates
Cell membraneForms protection (ex. Waterproofing) insulates body

Structure of Fat
2003-2004
not a chain (polymer) = just a “big fat molecule”

Lipids ExamplesSteroids-structure is a series of connected hexagonal rings. Cholesterol, hormone, cortizone.
Triglyceride- glycerol with 3 fatty acids; fats in food, associated with cholesterol.
Phospholipid- glycerol with 2 fatty acids; make up cell lipid bilayer membrane.
Fats: insulates, stores energy, solid at room temperture
Oils- liquid at room temp.

Saturated fatsMost animal fats
solid at room temperature
Limit the amount in your diet
contributes to heart disease deposits in arteries

Unsaturated fatsPlant, vegetable & fish fats
liquid at room temperature
the fat molecules don’t stack tightlytogether
Better choice in your diet
