Hydrogen bonds, as well as the other types of noncovalent interactions, are very important in terms of the binding of a ligand to a protein. In section 1.3, we saw a 'space-filling' picture of an enzyme with its substrate bound in its active site.
Noncovalent Bonding. Noncovalent bonding. 1  holds the two strands of the DNA double helix together (hydrogen bonds). 2  folds polypeptides into such secondary structures as the alpha helix and the beta conformation.3  enables enzymes to bind to their substrate.4  enables antibodies to bind to their antigen.oncovalent Bonding.
