In proteins, the hydrogen bonding responsible for the secondary
structure of a protein generally takes place between backbone
carbonyl oxygen atoms and amide hydrogen atoms. In contrast, the
hydrogen bonding that contributes to tertiary structure generally
occurs between amino acid side chains.Two serine residues are shown below, with possible hydrogen bonds
shown in green. Which bonds depict the hydrogen bonding that occurs
between serine residues and contributes to tertiary
structure?

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...
