Description | Alliin, also known as (S)-S-allyl-L-cysteine sulfoxide or (S)-3-(allylsulphinyl)-L-alanine, is a member of the class of compounds known as L-alpha-amino acids. L-alpha-amino acids are alpha amino acids which have the L-configuration of the alpha-carbon atom. Alliin is soluble (in water) and a moderately acidic compound (based on its pKa). Alliin can be found in a number of food items such as red rice, mandarin orange (clementine, tangerine), ceylon cinnamon, and olive, which makes alliin a potential biomarker for the consumption of these food products. Garlic has been used since antiquity as a therapeutic remedy for certain conditions now associated with oxygen toxicity, and, when this was investigated, garlic did indeed show strong antioxidant and hydroxyl radical-scavenging properties, it is presumed owing to the alliin contained within. Alliin has also been found to affect immune responses in blood . |
