In chemistry, and especially in organic chemistry, chirality is a property of primary importance, because molecules such as carbohydrates, many amino acids, as well as many drugs, are chiral. Organic molecules constitute the essence of life (fats, sugars, proteins, DNA), and also permeate our everyday lives (cotton, polyester, toothpaste, plastics, etc). In the CIP system of nomenclature, each chiral center in a molecule is assigned a prefix (R or S), according to whether its configuration is right- or left-handed. As part of ⦠mojack11.
