Document Summary

Definition: organic substances containing carbon, hydrogen and oxygen (much more c and h than cho) Fats are non-polymer molecules, so they don"t interact well with water. However, in heat they can be more soluble to form triglycerides. Phospholipid bilayer, lipid tail (nonpolar) phosphate group head (polar) the polar aspect interacts with the water. Insulation, adipose tissue is subcutaneous and around organs, so it provides insulation to maintain body temperature. Can regulate temperature because we have white and a little brown adipose tissue. Brown adipose tissue is more active metabolically (non-shivering temperature regulation). Brown adipose tissue produces heat and controls the temperature. Subcutaneous muscle contraction also creates heat production by shivering. Protection, a lot of fat surrounds internal organs visceral fat but excessive amounts create problems (high risk of. Shock absorber to remove stress that may be put on the organs. From fats we can mix some of the hormones, specifically cholesterol (which makes testosterone and estrogen).
