Document Summary
Just 11 elements make up 99% of body. Fats 20%; water 60 %, protein 20% Body first wants to consume sugar, then fats, then muscle. Promote growth and development: proteins, lipids, some vitamins, some minerals, water. Regulate body processes: proteins, some lipids, some vitamins, some minerals, water. Movement of muscle depends on chemical reaction. Without water nothing is transported and reacts. Macromolecule degradation > cell building blocks > oxidative respiration >ultimate metabolic products (nh3 (ammonia), h20, co2) Enzymes called lipases hydrolyze triacylglycerols into mono and diacyl glycerol. Fatty acids ch3(ch2)16cooh (very long chain of ch2) Saturated vs unsaturated: saturated has single bonds connecting carbons and has as many hydrogens as possible. Omega-3 (double bond at the end of the chain) alpha-bond in the beginning of chain. Trans fats: actually unsaturated fat, but normal oils have a bend at double bond while trans fat remains in straight line. Unsaturated fats are naturally liquid in form.
