Document Summary
Involved in fatty acid transport (forms outer shell of chylomicrons and lipoproteins): egg yolks, soybeans, peanuts, sterols, small percentage (<2%, most famous: cholesterol, precursor to hormones (sex and cortisol), vitamin d, and bile acids. Fatty acids: (cid:120) hydrocarbon chain (4-24 carbons) (cid:120) (cid:120) (cid:120) 18:0 (cid:120) example: butyric acid (4:0) provides the flavour in butter. 2% vs skim! (cid:120) stearic acid 18:0, chocolate, meat fats, solid at room temperature. Effect of chain length: (cid:120) longer chain = more solid at room temperature (cid:120) shorter chain = more liquid at room temperature (oils) lots of saturated fats - longer chain more solid at rt. Triglycerides functions: energy source, insulation/protection, improves bioavailability and transport of other fat-soluble nutrients, flavour, texture, odour of foods. Why warming up is a good idea, gives cvs a chance to catch up! starts the hormone-driven process of breaking down fats. Muscle cell w ab carnitine (2) mito acetyl coa.
