WebThey are characterized by the general formula (CH2O)n, where n is any integer from 3 - 7 (3 to 7 carbons in length). Monosaccharides are name based on either functional group or number of carbon atoms. A monosaccharide with a ketone group is referred to as a ketose. A monosaccharide with an aldehyde group is referred to as an aldose. WebAcetoin (AC) is an important platform bulk chemical with versatile applications. It exists in two stereoisomeric forms: (3R)-AC and (3S)-AC. Both stereoisomers could be potentially applied in the pharmaceutical industry, agriculture, and in optically active α-hydroxyketone derivative synthesis. Chiral AC production has recently become a new research focus in …
