Answers

1.   Amino Acids/Proteins, Carbohydrates, Lipids, and Nucleic Acids

2.   Amine and Carboxyl groups attached to the same group.

3.   2—Dipeptide; 3—Tripeptide; 4—Tetrapeptide; etc.

4.   Polymers made up of amino acids.

5.   1st level—sequence of amino acids; 2nd level—coiling of the peptide/protein; 3rd level— twisting of the coil

6.   Proteins that catalyze (speed up) chemical reactions. If you want to learn more check out Can mutations in sex cells be inherited?

7.   No, because they are on opposite sides.

8.   Carbon that is “hydrated” or has what attached.

9.   Monosaccharaides, Disaccharides, Polysaccharides

10. Monosaccharides cannot be split into smaller carbohydrates by hydrolysis; Disaccharides  can be split into 2 smaller carbohydrates by hydrolysis; Polysaccharides are carbohydrate  polymers Don't forget about the age old question of How does historical criticism affect the writing of history?

11. Lipids are biological molecules that are soluble in non­polar solvents. Fatty acids are long chains of carboxylic acids (add to glycerine to get a fat).

12. Hexagonal shaped molecules that enhance body by releasing hormones. 13. Pentose, Amine Base, and Phosphate 

14. DNA is a double stranded nucleic acid with deoxyribose in both the cell nucleus and  mitochondria. RNA is a single stranded nucleic acid with ribose that is both a messenger  and transfer of genetic information

15. Nucleotides are monomers of Nucleic Acids (they make up Nucleic Acids).

16. The mapping of all Human genes to find the estimate of how many are in the body  (>30,000).

17. Energy and building material (biological molecules).

18. Carbohydrates 

19. Nutrients that prevent diseases of proficiency. There are Water­soluble and Fat­soluble. 20. Fatty acids and amino acids that are not made by the body directly and so have to be  ingested (eaten) to be obtained.

21. Improve nutritional content, Alter color, Prevent spoilage, and Enhance flavor

22. Measure of how fast a source of glucose (carbohydrate) is converted to blood glucose  where glucose has the value of 100.

23. French people had lower indexes of mortality due to high blood cholesterol as compared  to U.K. and U.S. If you want to learn more check out What is tacit collusion in oligopoly?
If you want to learn more check out What does peak load mean?

24. Dose, Chemical nature of substance, How you are exposed

25. Lethal Dose for 50% of Test Population; measurement of how much one would need to  take for a substance to be lethal.

26. Metals of large atomic masses (ex. Mercury, lead, copper)

27. Carcinogens are toxins that can cause cancer. Mutagens are toxins that cause mutations in DNA. Teratogens are toxins that induce birth defects. 

28. Nerve poisons that interfere with neurotransmission.

29. Toxins that break down peptides and Proteins, leaving a chemical burn.

30. Manufactured drugs by altering the chemical substance of narcotics, stimulants, and other drugs to make them produce similar effects.

31. It contains basic information about the characteristics, limits, and potential  hazards of a chemical.
