Document Summary
Precursor of both steroid hormones (testosterone, estrogen) and bile acids (fat digestion) Involved in triacylglycerol (triglyceride) transport in the blood. Part of diet (found in animal products and foods prepared with animal products, i. e. , eggs, butter, etc) Recommendation=100mg/1000 kcal but association with heart disease probably not as important as once believed (unless abnormal cholesterol metabolism: phospholipids. Similar to triacylglycerol (glycerol base and a fatty acid or two) but also a phosphate group. Chains of c,h, and o (mostly even number of c from 12-22) Component part you split off and use for energy. Mostly even numbers b/w 12-22 more c and o than glucose so a lot of energy, but to mobilize this need a lot of oxygen. Harder you go, more you rely on anaerobic energy production because demand of exercise exceeds ability to take up and deliver o2. Vary in saturation of c with h (saturated, monounsaturated, polyunsaturated) Can have saturated- 4 h for each c.
