Document Summary
Cho (very little o) e. g. stearic acid: c18h36o2. Triglyceride: glycerol backbone, 3 fatty acid chains (for a triglyceride) Phospholipid: one polar head with a phosphate group, hydrophilic loves water, oriented toward the water-containing parts of the cell, ecf, icf (cytoplasm, two non-polar tails, hydrophobic hates, oriented away from the water water. Steroids: hormones (mainly sex, vitamin d vital for bone growth, cholesterol precursor of bile salts, vitamin d, steroid hormones. Polyunsaturated fats: 1+ double covalent bond between its c atoms, not completely saturated with h atoms, olive oil and peanut oil, liquid at room temperature. Phospholipids: 2+ double covalent bonds between its c atoms, corn, safflower, and sunflower oil, research: diets high in polyunsaturated fats lead to lower cholesterol in blood cell membrane (plasma membrane) Cell specialization: the tendency of a particular cell type to have a special shape or structure, related to the special functions the cell carries out, increases the efficiency of the body.
