Document Summary
Hygrogen and carbon together through non-polar covalent bonds. Triglycerides: glycerol + 3 fatty acids: saturated: all carbons linked by single covalent bond. High melting point, solid at room temp: unsaturated: cabon carbon double bonds. Liqiud at room temp: trans fat: unsaturated fats. Hydrolysis of trigcerides releases fatty acids from glycerol fatty acid = metabolize = energy energy from c h c oh. Fats store more energy cushion organs, insulation etc . Phospholipids: hydroxyl group of glyercol linked to phosphate group. Not very water soluble (non-polar: cholestrol: biosynthesis to fat metabolism. Can be converted to other steroids by modifying side gorups: hormones: type of steroid estrogen and testosteron different side groups. Waxes: very non-polar, repel water, long hydrocarbon structures resemble fatty acids. Ion channels: movements of charged molecules across plasma membrane. Amino acids: building blocks: amino group + charge, carboxyle group charge, zwitterion: neutral molecule positive and negative. Amino acids formed by linking carboxyl grop: peptide bond: 4 levels of organization.
