Webα,β-Unsaturated carbonyl compounds featuring a carbonyl conjugated to an alkene that is terminal, or vinylic, contain the acryloyl group (H 2 C=CH−C(=O)−); it is the acyl group derived from acrylic acid.The preferred IUPAC name for the group is prop-2-enoyl, and it is also known as acrylyl or simply (and incorrectly) as acryl.Compounds containing an … WebIn glucose and galactose, the carbonyl group is on the C 1 carbon, forming an aldehyde group. In fructose, the carbonyl group is on the C 2 carbon, forming a ketone group. The former sugars are called aldoses based on the aldehyde group that is formed; the latter is designated as a ketose based on the ketone group.
