Concept explainers
To determine: The reason why glycine has no stereoisomers.
Introduction:
The amino acids or compounds that contain same molecular formula but different molecular structure are termed as isomers. The isomers that are differing with each other in spatial arrangements and contain the same bond formation are termed as stereoisomers.
Amino acids contain a central carbon atom, a hydrogen atom, an amino group (NH2), a carboxyl group (-COOH), and an R-group. Amino acids occur in L (laevorotatory) or D (dextrorotatory) form and L and D form are termed as stereoisomer. The two amino acids are mirror images of each other; hence they occur in two forms. D-form amino acids causes the bending of light clockwise while L-form amino acids causes the bending of light anti-clockwise

- What structural features do a triacylglycerol and a phosphatidylethanolamine have in common? How do the structures of these two types of lipids differ?arrow_forwardIn the monosaccharide derivatives known as sugar alcohols, the carbonyl oxygen is reduced to a hydroxyl group. For example, D-glyceraldehyde can be reduced to glycerol. However, this sugar alcohol is no longer designated D or L.
