WebChirality is an important concept for stereochemistry and biochemistry. Most substances relevant to biology are chiral, such as carbohydrates ( sugars, starch, and cellulose ), … WebAn enantiopure drug is a pharmaceutical that is available in one specific enantiomeric form. Most biological molecules (proteins, sugars, etc.) are present in only one of many chiral forms, so different enantiomers of a chiral drug molecule bind differently (or not at all) to target receptors. Chirality can be observed when the geometric ...
