| Common Name | Cycloalliin |

| Description | Cycloalliin belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Cycloalliin has been detected, but not quantified in, several different foods, such as welsh onions (Allium fistulosum), onion-family vegetables, garden onions (Allium cepa), green onion, and soft-necked garlics (Allium sativum L. var. sativum). This could make cycloalliin a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Cycloalliin. |
