Abstract
It is assumed that genetic diseases affecting the metabolism of cysteine and the kidney function lead to two different kinds of pathologies, namely cystinuria and cystinosis whereby generate l-cystine crystals. Recently, the presence of l-cysteine crystal has been underlined in the case of cystinosis. Interestingly, it can be strikingly seen that cystine ([–S–CH2–CH–(NH2)–COOH]2) consists of two cysteine (C3H7NO2S) molecules connected by a disulfide (S–S) bond. Therefore, the study of cystine and cysteine is important for providing a better understanding of cystinuria and cystinosis. In this paper, we elucidate the discrepancy between l-cystine and l-cysteine by investigating the theoretical and experimental infrared spectra (IR), X-ray diffraction (XRD) as well as Raman spectra aiming to obtain a better characterization of abnormal deposits related to these two genetic pathologies.
