Question

In standard stereochemical nomenclature, the structural prefixes "D" and "L" are routinely applied to carbohydrates and amino acids. What explicit stereochemical property do these specific letters indicate?

Prashant Kotian · Accepted Answer

Correct answer: B. D/L nomenclature is a relative configuration system natively referenced to the arbitrary standard of Glyceraldehyde. It has absolutely no direct correlation to the absolute R/S system, nor does it reliably predict the optical rotation direction (+ or - / d or l) of plane-polarized light.
