However 80% of cholesterol made by our bodies. Consumption in north america and europe: more fish (lvled off in 2006) and poultry, less beef. To raise chickens, more methionine is needed (aa in food) used as feed supp. To make methionine: need methy mercaptan (foul smelling gas (cid:271)ut is (cid:373)ade i(cid:374)to li(cid:395)uid form) ch3-s-h add with acrolein, h-cn, h20 methionine. 10 billion chickens (consumed in us) = 100 million lbs methy mercapton needed to feed the chickens. Chicken feathers (2. 5 billion lbs) = mostly protein makes mulching film, anti-hurricane roofing, biodegradable plates, etc. Fish becoming less due to overfishing eat for omega 5 (double bond of unsat 5 c from the end of the c chain)
