PHYSIOL 596 Chapter Notes - Chapter 4: Unsaturated Fat, Saturated Fat, Trans Fat
Document Summary
In a hydrocarbon chain, carbon must have 4 covalent bonds (see pics in txt) Saturated : linear shape (straight w/ no kinks) easily stored and stacked solid at room temperature butter. Unsaturated : bent shape (forms kinks) body prefers to use this than store it liquid at room temperature olive oil good source of lipids is a balance of saturated vs unsaturated (more unsaturated) Legnth does not tell if healthy or not but shape does (paper stacking example) Monounsaturated: one c to c double bond. Polyunsaturated: more than one c to c double bond. C to c double bond in nature= cis. C to c double bond not in nature= trans. 3 and -6= reflect the position of the double bonds. Molecules beneficial to the cardio v. system. 3= walnuts and fish, alpha linolenic acid. Phospholipids= 2 fa, 1 glycerol, 1 chlorine. Consumption bad cause we make it ourselves (cells synthesize it)
