What is the chemical formula for a sulfhydryl or thiol group?

The chemical formula for a sulfhydryl or thiol group is represented by R-SH. In this formula, "R" represents a hydrocarbon chain or a functional group that is attached to the sulfur atom (S). The "SH" part specifically indicates the presence of a sulfur atom bonded to a hydrogen atom, which is characteristic of thiol groups. Thiols are known for their strong and distinct odors and are important in various biochemical processes, including the formation of disulfide bonds in proteins, which can influence protein structure and function. The presence of the sulfhydryl group in biomolecules makes it a key functional group in biochemistry.
