What is Thioester?
[[Image:Thioester-2D-A.svg|thumb|right|150px|General structure of a thioester]] A '''thioester''' is a [[molecule]] with a [[functional group|group]] C-S-CO-C. They are like [[ester]]s, but with a [[sulfur]] atom instead of an [[oxygen]] one. Like esters, they can be made from [[carboxylic acid]]s. In the synthesis, a [[thiol]] is used instead of an [[alcohol]]. Thioesters are very important in [[biochemistry]]. They are made in the body during [[chemical reaction|reactions]] that make [[fatty acid]]s. They are also important [[intermediate]]s in the production of ATP, which is the molecule that gives [[energy]] to the body. In [[chemistry]], thioesters can be also used as [[electrophile]]s. They are more reactive than esters and [[amide]]s. They can also do [[aldol reaction]]s. {{functional group}} [[Category:Functional groups]] [[Category:Organosulfur compounds]]
