Describe the term D- and L-configuration used for amino acids with examples.
Answers (1)
There are only two types of sugar present in the amino acid family: definitively configured D-Family and L-Family. The key difference in the configuration of these families is decided by the glyceraldehyde. The presence of glyceraldehyde is taken as the standard, and it can be found in two forms:
L-(-)-Glyceraldehyde configuration and the D-(+)-Glyceraldehyde. The positioning of the -OH group of the carbon adjacent to CH2OH categorises the configuration. If the group is attached to the right side, then it would be of D-configuration but the positioning of -OH group on the left makes it of L-configuration. The natural sugars present are all of D-configuration.
