25
Functions of lipids
* reserve energy * insulation * protection
26
Polyunsaturated fats
Oily
27
Saturated fats
Harder
28
Fats are
Not healthy, cardiovascular disease
29
Hard fats
Clog arteries, thrombosis
30
Must include fats in diet
Omega 3 fatty acids, normal metabolic reactions, some vitamins are fat soluble, phospholipids
31
Cholestrol
Essential for forming of cell membrane, too much can lead to plaques in blood vessels
32
Steroids
Formed from fats
