Which functional group is primarily involved in forming disulfide bonds between organic molecules?
Understand the Problem
The question is asking about the specific functional group that plays a key role in the formation of disulfide bonds between organic molecules. Disulfide bonds are important in stabilizing the structure of proteins and are formed through the oxidation of sulfhydryl groups.
Answer
Thiol group (–SH) of cysteine residues.
The functional group primarily involved in forming disulfide bonds is the thiol group (–SH) of cysteine residues.
Answer for screen readers
The functional group primarily involved in forming disulfide bonds is the thiol group (–SH) of cysteine residues.
More Information
Disulfide bonds are formed by the oxidation of the thiol groups of cysteine residues, creating a covalent bond between sulfur atoms. These bonds are crucial for the structural integrity and stability of many proteins.
Tips
It's important not to confuse the thiol group with other sulfur-containing groups, such as sulfates or sulfides, which do not participate in forming disulfide bonds.
