Can cysteine form hydrogen bonds
WebTwo cysteine residues can form hydrogen bonds. Side chains that can form hydrogen bonds are located on the outside of a protein, where they can stabilize tertiary structure by forming hydrogen bonds with water. Hydrogen bonds stabilize quaternary protein structure by holding together several protein strands. WebJan 30, 2024 · Intramolecular hydrogen bonds are those which occur within one single molecule. This occurs when two functional groups of a molecule can form hydrogen bonds with each other. In order for this to …
