1. Which of the following is NOT a component of a standard amino acid?
Amino group
Carboxyl group
Phosphate group
R-group (side chain)
2. The bond formed between two amino acids is called a:
Glycosidic bond
Ester bond
Peptide bond
Hydrogen bond
3. There are common amino acids that make up proteins.
4. The unique properties of each amino acid are determined by its .
5. Amino acids are the monomers that link together to form .
6. All amino acids are chiral, meaning they have a mirror image that is non-superimposable.
True
False
7. Essential amino acids can be synthesized by the human body.
True
False
8. Describe the general structure of an amino acid, highlighting its key functional groups.
9. Explain the importance of the R-group (side chain) in determining the characteristics of an amino acid.
Use the words below to complete the sentences.
10. At physiological pH, amino acids exist as a , having both a positive and negative charge.
11. Amino acids with nonpolar R-groups are generally and tend to be found in the interior of proteins.
12. A chain of multiple amino acids linked by peptide bonds is called a .
