WebFeb 13, 2015 · The thioether functional group is introduced in the last step of the biosynthetic pathway. The precursor dethiobiotin contains a methyl group at C9 derived from l-alanine and a methylene group at C6 derived from pimelic acid (9). Biotin synthase inserts a sulfur atom between these two positions. WebA thioether is a molecule with the group R-S-R. The first atom in R is a carbon. Thioether take their name from ethers. They have a sulfur instead of an oxygen atom between the two R. Thioethers can have very bad smells like thiols. They can also be called sulfides. The C-S-C bond is at nearly 90 degrees. Thioethers are important in biology.
