WebCysteine contains a thiol (-SH) group and can form covalent bonds with other cysteines. ... Peptide bond formation is not an acid-base reaction. Peptide bonds are covalent bonds that form through dehydration (loss of a water molecule). Biological acid-base reactions typically involve transfers of hydrogen ions (aka protons or H⁺). WebMar 16, 2024 · Significance The development of K-Ras G12C covalent inhibitors suggests that this strategy could lead to therapeutic agents directly targeting Ras. Unfortunately, the overwhelming majority of Ras mutants and all Ral proteins do not have an accessible cysteine residue.
