R-SH
RSH - condensed general formula of compound CH3SH - methyl thiol
Thiol and acid chloride form thio esters and Hcl.
The s-h functional group is called a thiol group. Thiol groups consist of a sulfur atom bonded to a hydrogen atom. They are characterized by their strong odor and ability to form disulfide bonds with other thiol groups.
An alkanethiol is a simple aliphatic thiol.
Thiol.
It is used to treat skin diseases.
CH3-CH2-CH2-CH2-SH
cysteine
No, thiols do not contribute a negative charge. A thiol is characterized by the presence of a sulfur atom bonded to a hydrogen atom and has the general formula R-SH. In its neutral state, it carries no net charge; however, thiols can potentially donate a proton (H+) in certain conditions, acting as weak acids, but this does not imply they inherently contribute a negative charge.
The functional group of cysteine is a thiol group, also known as a sulfhydryl group, which consists of a sulfur atom bonded to a hydrogen atom. This thiol group is important for the formation of disulfide bonds in proteins, which play a role in the structure and function of proteins.
It will be different for different thiols.
In organic chemistry, an allenylthiol is a thiol which has an allene group.
