Document Summary
Definition: the chemical composition and reaction of living matter. Bio compounds: inorganic, water, salts, acids, bases, organics, contains carbon, can interact with covalent bonds, the important one we look at today: carbs, proteins, lipids, nucleic acids. Important inorganic compounds: water, a lot of properties that make life possible, properties, high heat capacity: water is resistant to changes in temperature. It is good to have something in our bodies to resist changes: high heat of vaporization: to change from water to vapor requires a lot of energy, universal solvent. It if can ionize, it will dissolve in water. Virtually all reactions that take place inside of the body, take place in water: hydrolysis/condensation. We get more energy (about 10x) from fat than carbs: it protects and insulates (especially kidneys, neutral fats are triglycerides, glycerol component and three fatty acids. Animals produce more saturated fats than plants, often called animal fats. Double bond between any of the carbons.
