“Amino acids used in making a polypeptide have an amino group and carboxyl group, and these groups can be present on any carbon atoms.” Is that a correct statement? Why so? What is the basis for classification of amino acids to non-polar (but not aromatic), polar, and two oppositely charged (at physiological pH) amino acids? Provide examples with their exact name, three letter and single letter codes.

Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids
Distinguish between the different levels of protein structure, including primary, secondary, tertiary, and quaternary Question Is the following statement true? If not, explain why not: Since the secondary structure of a protein results from hydrogen bonding between components shared by all amino acids (a hydrogen on an amide N on one amino acid interacts with an oxygen on the carbonyl of another amino acid), the secondary structure does not depend on the specific amino acid groups (the R-groups) in the amino acid chain. Select...
