Biochemistry

2. Breaking down complex molecules (polymers) by the chemical addition of water. Used in digestion
6. "Compound containing carbon, hydrogen, and oxygen in the approximate ratio of C:2H:O
9. Water-fearing"; pertaining to nonpolar molecules (or parts of molecules) that do not dissolve in water
11. Monomer of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base
12. compound a covalently bonded compound that contains carbon
15. A substance that speeds up the rate of a chemical reaction
16. energy The minimum amount of energy needed to start a chemical reaction
18. Class of nutrients made up of amino acids. They are needed to build and repair body structures, and to regulate processes in the body
20. A molecule of any compound that can react with other molecules of the same or different compound

1. A large molecule composed of repeating structural units
2. "water-loving"; pertaining to polar or charged molecules (or parts of molecules) that are soluble in water
3. acid A biological macro-molecule (DNA or RNA) composed of the elements C, H, N, O, and P that carries genetic information.
4. Bond created by the weak attraction of a slightly positive hydrogen atom to a slightly negative portion of another molecule
5. A very large molecule (as of a protein, nucleic acid, or carbohydrate) built up from smaller chemical structures
7. A protein that makes a reaction happen QUICKER; decreases activation energy of a reaction.
8. a simple carbohydrate molecule
10. synthesis A chemical reaction in which two molecules covalently bond to each other with the removal of a water molecule
13. Attraction between molecules of the same substance
14. a large carbohydrate molecule
16. An attraction between molecules of different substances
17. Organic molecules made of carbon, hydrogen, and oxygen and store food energy until needed (Fats)
19. acid Building blocks of protein
