Document Summary
Study guide chapter 4: digestion and absorption of lipids (part 1: chemical structure of a fatty acid and a triglyceride. Fatty acid head (fa), triglyceride tail (3 strands) -or- phospholipid head (with phosphate groups) and glycerol tail: understand the naming of fatty acids (both delta and omega nomenclature) Omega (or n -6): (end) start @ terminal . # c"s : # double bonds : (delta /omega) #location of double bond: what are examples of essential fatty acids and what are their physiological functions. Polyunsaturated, can"t be synthesized by body (omega 3 is anti-inflammatory! Linoleic acid (6): arachidonic acid synthesis > synthesis of lipid mediators (eicosanoids) Linolenic acid (3) : membrane lipids for structure (in retina and brain) > epa (eicosapentaenoic acid??) *omega 6 & 3 can"t be interconverted, but the derived molecules later in the pathway can: know what, if any, digestion of lipid occurs in the mouth and stomach, and the enzymes responsible.
