Chemical Information
FooDB NameS-Allylcysteine
DescriptionS-Allylcysteine 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. S-Allylcysteine is a cooked and roasted tasting compound. S-Allylcysteine is found, on average, in the highest concentration within soft-necked garlics (Allium sativum L. var. sativum). S-Allylcysteine has also been detected, but not quantified in, several different foods, such as red onion, welsh onions (Allium fistulosum), garlics (Allium sativum), green onion, and onion-family vegetables. This could make S-allylcysteine a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on S-Allylcysteine.

immunostimulant50847 A substance that augments, stimulates, activates, potentiates, or modulates the immune response at either the cellular or humoral level. A classical agent (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contains bacterial antigens. It could also be endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Its mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy is related to its antigen-specific immunoadjuvanticity.DUKE
