Document Summary
Water insoluble). also made of cho, but more. C and h in proportion to o -> can supply more energy than carbs. Triglyceride: glycerol x 1, fatty acids (carbon chains) x 3. Fatty acids 1-24 c long (only even #). Can be saturated or not (mono or poly) polyunsat. Important ones are those with first point of unsaturation next to 3rd or 6th c (omega 3 or 6) (count from methyl end) -> linolenic, linoleic acid -> regulate blood clotting, pressure, etc. Fatty acids: organic acid, c chain with cooh acid group one end and methyl on other end. 18 c long fatty acids are abundant in food. Mufa: (mono) missing two h because of double bond, usually omega-9 group (oleic acid, olive oil) Pufa: (poly) missing four or more h (double bonds). Double bond is point of unsaturation, each one displace 2 h, is one degree of unsaturation.
