Did you know?
WebThe general formula for determining the maximum number of stereoisomers of a molecule is 2 n, where n is the number of chiral centers present in the molecule. IN the case of glucose, carbons 2, 3, 4, and 5 are chiral centers. Therefore, there are 2 4 = 2 x 2 x 2 x 2 = 16 stereoisomers of the molecule. 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 …
