Document Summary
Energy provide per gram is greater than in carbs. Methyl group at one end, acid group at the other end. Usually an even number of carbons: 18-carbon fatty acids are abundant in food. Saturated fat: full of hydrogen, no double bonds. Unsaturated fat: missing hydrogen, has double bonds. Essential fatty acids: **linolenic acid (omega 3) allows body to make dha and epa (from salmon and tuna**, ** linoleic acid (omega 6) form vegetable oils and meat. Double bonds are near the methyl end of the carbon chain. Omega number represents the location of the closest double bond from methyl end: omega-3 is closest double bond is 3 carbons away from methyl end. Triglycerides the chief form of fat in your diet** Major way your body stores fat** three fatty acids attached to a glycerol formed via condensation. Usually contains a mixture of fatty acids. Provide the cells with energy ( virtually unlimited ability to store fat energy)
