Document Summary
Glycerol is a 3 c alcohol that is not lipid soluble. It is the backbone of a tg (carboxylic acid end = cooh) Fatty acid: chain of carbon atoms bound to hydrogen (methyl end = ch3) (obtained in the diet and made in the liver from excess glucose & protein) Chain length major names based off chain length. Degree of saturation/number of double bonds: saturated: no double bonds - every carbon is saturated with hydrogen, can pack tightly together to be solid at room temp (animal sources have more saturated fatty acids) (sources of. The hydrogen atoms at the unsaturated region can be arranged in different positions. Some trans fatty acids found naturally in foods, rest produced by hydrogenation: the addition of hydrogen atoms to unsaturated fatty acids. Converts liquid fats (oils) into a semi-solid (spreadable) or solid form. Listed on the food label as partially hydrogenated oil.
