Document Summary
Shape impacts stacking ability and fluidity: long chain saturated fa stack well to make solids at room temperature, monounsaturated and polyunsaturated not stack well because bent, liquid. Tg are major form of lipid in food and in body. Essential fa important for growth, skin integrity, fertility and structure and. 3 fa: long chains of carbon bonded to each other and hydrogen. 1 glycerol: 3-carbon alcohol, backbone of tg function of cell membranes. Symtoms: dry scaly skin, liver abnormalities, poor wound healing, growth failure in infants, impaired hearing and vision. Essential fa deficiency: omega-6 fa (main dietary source linoleic, veg oil, seed oil, nut, omega-3 fa (main dietary source alpha-linoleic) Bent because hydrogen on the same side of double bonds. Liquid at room temperate because high in unsaturated fatty acids and bent chains. Straight, difficult for body to process because hydrogen on opposite sides of double bond (similar to shape of saturated fatty acid)
