FooDB Name | (±)-Cystine |
---|
Description | (±)-Cystine, also known as dicysteine or cistina, belongs to the class of organic compounds known as cysteine and derivatives. Cysteine and derivatives are compounds containing cysteine or a derivative thereof resulting from reaction of cysteine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom (±)-Cystine is found, on average, in the highest concentration within a few different foods, such as red bell peppers (Capsicum annuum), italian sweet red peppers (Capsicum annuum), and green zucchinis (Cucurbita pepo var. cylindrica) and in a lower concentration in green bell peppers (Capsicum annuum) and beer. This could make (±)-cystine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on (±)-Cystine. |
