WebDec 10, 2014 · Dec 10, 2014. The D and L prefixes refer to the side of the highest-numbered chiral centre in a Fischer projection. The prefix "D" comes from the Latin word dexter. It means "on the right side". The prefix "L" comes from the Latin word laevo. It means "on the left side". We usually see the terms D and L when talking about sugars and amino acids. WebVideo transcript. - [Lecturer] In the last video, we looked at a Fischer projection of a compound that had only one chirality center. This molecule has two, and our goal is to determine the configuration of each chirality center, so at the intersection of these lines here, we know that this is a chiral center and then we have another one down ...
