The cysteine sulfhydryl group is nucleophilic and easily oxidized. The reactivity is enhanced when the thiol is ionized, and cysteine residues in proteins have pKa values close to neutrality, so are often in their reactive thiolate form in the cell. Because of its high reactivity, the sulfhydryl group of cysteine has numerous biological functions. WebMar 31, 2024 · Furthermore the weak bonds that are represented as a broken line, is a well known way to describe a hydrogen bond. This activity also has great accuracy because replication is clearly shown by marking down the 5’ to 3’ and 3’ to 5’ to explain that when DNA is replicated it is replicated using the 5’ to 3’ side.
