Cystein r konfiguration
WebOnly cysteine has a R configuration. The reason why most amino acids are S is because the R side group of amino acids is usually the lowest priority when assigning groups for stereochemistry. It just so happens that in cysteine, the sulfur atom is directly attached to the carbon R group, allowing it to have a higher priority leading to the R ... Webcysteine (R-configuration) Cystine.
