Document Summary

Amino group (nitrogen) , carboxyl group (acid), hydrogen group and r-group (side chain) This r-group is unique in each amino acid. An amino acid that must be consumed in order to meet dietary needs. An amino acid that can be produced in the body. Made through transamination which is the transfer of nitrogen"s to create new am. A normally non-essential but due to illness or other factor the body cannot make it in ad. Therefore in this time it becomes an essential amino acid. Because proteins have a charge which creates a 3-d shape. The shape of a protein determines what other things it can bond to and therefore how it. Growth/maintenance, repair, hormones, energy, fluid balance, acid-base balance, immuni. Protein turnover can"t occur if there is a limiting amino acid. Benefits: lower risk for heart disease, lower bmi, reduced risk of cancer. Animal proteins, milk, soy , meats, egg whites.

1. Polypeptide strands is the active form of a digestive enzyme in the stomach that breaks polypeptide chains into smaller polypeptides.

2. Cleavage of proteins by pepsin in the stomach results in formation of pepsinogen which get broken down further in the small intestine.

3. An amino acid chain made up of three amino acids joined together is called a tripeptide.

4. Dipeptide describes an amino acid chain made up of two amino acids joined together.

5. The 20 different amino acids are the building blocks used for protein synthesis.

6. Amino acid pools are stockpiles found in the blood and other cells of the body that can be used to build new proteins.

7. The continual process of degrading and synthesizing protein is called protein turnover.

8. The stomach produces pepsin, which denatures protein.

9. Denaturation occurs when a protein is exposed to heat, acid, bases, or mechanical agitation resulting in unfolding of the protein, though the peptide bonds remain intact.

10. The part of an amino acid that contains nitrogen is called the amine group.

11. The acid group is also known as the carboxyl group.

12. Single amino acids that are absorbed in the small intestine travel to the liver via the portal vein.

7. What are essential amino acids? How are they different from non-essential amino acids? Do all organisms have the same set of essential amino acids? What role do essential amino acids play in human biochemistry?

8. How and why are protein molecules affected by the pH of their environment? How can the Henderson-Hasselbalch equation be used to tell us about the response of protein molecules to changes in pH?

9. Describe the use of affinity chromatography and explain why it is such a powerful technique for purifying proteins. Why is it more powerful than most other methods.

10. Many biological compounds could potentially exist as more than one stereoisomer, but only one steric form is used for a given function. Why is the selection of only one steric form a necessary feature of living organisms? What would happen to the protein product if an organism could randomly add either D- or L-amino acids during protein synthesis.
