Thiol - Wikipedia
In organic chemistry, a thiol (/ ˈ θ aɪ ɒ l /; [1] from Ancient Greek θεῖον (theion) 'sulfur' [2]), or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent.
Thiols and Sulfides - Chemistry LibreTexts
A thiol is a compound which contains an SH functional group. The -SH group itself is called a mercapto group. A disulfide is a compound containing an -S-S- linkage.
18.7 Thiols and Sulfides - Organic Chemistry - OpenStax
Thiols, also called mercaptans, are sulfur analogs of alcohols. They are named by the same system used for alcohols, with the suffix -thiol used in plac...

2015年7月5日 · Thiols and Thioethers: Properties and Key Reactions. If you can get beyond their foul smells, thiols have a lot of similar characteristics to alcohols! Like alcohols, they can be deprotonated with base and undergo SN2 reactions with alkyl halides to give thioethers (sulfides).
Thiol | Organic Chemistry, Sulfur Compounds, Mercaptans
Thiol, any of a class of organic chemical compounds similar to the alcohols and phenols but containing a sulfur atom in place of the oxygen atom. Thiols are among the odorous principles in the scent of skunks and of freshly chopped onions; their presence in petroleum and natural gas is.
6.8: Thiols (Mercaptans) - Chemistry LibreTexts
2021年5月20日 · Thiols, which are also called mercaptans, are analogous to alcohols. They are named in a similar fashion as alcohols except the suffix -thiol is used in place of -ol. By itself the -SH group is called a mercapto group. The main physical characteristic of thiols is their pungent, disagreeable odor.
Thiols: Functions, Identification, and Applications
2024年2月28日 · What is a Thiol? A thiol, in its most fundamental definition, is a chemical compound characterized by the presence of a sulfhydryl group (-SH). This molecular arrangement comprises a sulfur atom bonded to a hydrogen atom.
3.5: Thiols - Chemistry LibreTexts
The longest continuous chain of carbon has six carbon atoms in a ring, so the stem name is cyclohexane. The parent name is obtained by adding the word thiol, to give cyclohexanethiol. The carbon that has the sulfhydryl group is assigned as C1, since any carbon in the ring can be C1.
Organosulfur compound - Thiols, Structure, Reactions | Britannica
Thiols and thiol-derived compounds have several important roles in biology. As thiolate, RS −, they can function as bases, as ligands (e.g., in the binding of metals, as in hemoglobin), and as agents for the transfer of acetyl groups (e.g., in acetyl CoA) in lipid biosynthesis.
The role of thiols in antioxidant systems - PMC
In this review, we will discuss the role of protein thiols as scavengers of hydrogen peroxide in antioxidant enzymes, use thiol peroxidases to exemplify how protein thiols contribute to redox signaling, provide an overview over the diverse set of low molecular weight thiol-based redox systems found in biology, and illustrate how thiol-based ...
