Chiral centers for glucose
WebWhen a molecule such as glucose converts to a cyclic form, it generates a new chiral center at C-1. The carbon atom that forms the new chiral center (C-1) is called the anomeric carbon. Anomers are special cases … WebAnswer A chiral center, or chiral carbon, is a carbon atom that is bonded to four different groups. A molecule with a single chiral center has two enantiomers, designated D and L (or in the RS system, S and R). ... A nucleotide molecule has three components: a nitrogenous organic base, a five-carbon sugar, and phosphate. Glucose is a six-carbon ...

WebC. glucose which of the following monosaccharides has a structure in which two or more chiral centers are present? A. glyceraldehyde B. dihydroxyacetone C. glucose D. more than one answer E. no answer D. more than one answer the left and right handed forms of a monosaccharide with a single chiral center are A. enantiomers B. diastereomers WebExplanation: Diastereomers are compounds that contain two or more chiral centres and are not mirror images of each other. For example, the aldopentoses each contain three chiral centres. Thus, D-ribose is a diastereomer of D-arabinose, D-xylose, and D-lyxose. Epimers are diastereomers that contain more than one chiral center but differ from ...
