Question

How is tertiary structure maintained?

1) via hydrogen bonding between R groups
2) via ionic bonding between R groups
3) via covalent bonding between R groups
4) all of the above

Answer 1

All three of these bonds hold the R groups of the amino acids together.

Step-by-step explanation:

The structures are stabilized by multiple interactions, specifically side chain functional groups which involve hydrogen bonds, salt bridges, covalent disulfide bonds, and hydrophobic interactions.

- Hydrogen bonding

- Salt bridges (ionic bonding)

- Covalent disulfide bonds (Covalent Bonding)

- All in R groups
