Document Summary
Saturation- highly saturated fats lead to the risk of heart disease. Triglycerides (3 fatty acids on a glycerol backbone) One of the fatty acids is replaced by a phosphorus component. These are not a nutrient- you make them when you need them. Involved in cell membrane structure and cell signaling. Contributes to heart disease, builds up in your arteries and eventually leads to heart attack. Need cholesterol (but not a nutrient), however, you are capable of the synthesis of cholesterol. Storage form of energy, almost all calories are stored as fat, this is not true for plants (they store calories as starch) Regular menstruation (maintaining regular estrogen), also need estrogen for your bones. We need it, we cannot synthesize it in the diet (cannot synthesize. Omega-3, 4 or 6 fatty acids, however, you can elongate them) Bile (made in the liver, stored in the gall bladder, secreted into the small intestine as needed)
