Thiolysis
Thiolysis
Thiolysis (/θaɪˈɒlɪsɪs/; from the Greek words thio meaning "sulfur" and lysis meaning "loosening" or "breaking down") is a biochemical process involving the cleavage of chemical bonds by the addition of a sulfhydryl (SH) group.
Etymology
The term "thiolysis" is derived from the Greek words thio which means "sulfur" and lysis which means "loosening" or "breaking down". It refers to the process where a sulfhydryl (SH) group is added to cleave chemical bonds.
Process
In thiolysis, a coenzyme A (CoA) molecule, which contains a sulfhydryl group, is used to cleave a biochemical bond. This process is a key step in fatty acid oxidation, where it breaks down long-chain fatty acids into two-carbon units. Thiolysis also plays a crucial role in the Krebs cycle, a series of chemical reactions used by all aerobic organisms to generate energy.
