Allicin is an organosulfur compound obtained from garlic and leeks. [1] When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic. [2] Allicin is unstable and quickly changes into a series of other sulfur-containing compounds such as diallyl disulfide. [3]
Diallyl disulfide and the related trisulfide are produced by decomposition of allicin, which is released upon breaking the cells of the Alliaceae plants, especially garlic. The diallyl disulfide yield is the highest for the steam distillation of garlic bulbs which contain about 2 wt.% of diallyl disulfide-rich oil. Diallyl disulfide can also be ...
Garlic cloves are used for consumption (raw or cooked) or for medicinal purposes. They have a characteristic pungent, spicy flavor that mellows and sweetens considerably with cooking. [51] The distinctive aroma is mainly due to organosulfur compounds including allicin present in fresh garlic cloves and ajoene which forms when they are crushed ...
Alliin / ˈ æ l i. ɪ n / is a sulfoxide that is a natural constituent of fresh garlic. [1] It is a derivative of the amino acid cysteine.When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic.

1. May have anti-viral effects. Garlic has long been associated with immune-boosting and anti-microbial benefits. Most of the health benefits found in garlic come from the sulfur compound allicin ...
In garlic, an alliinase enzyme acts on the chemical alliin converting it into allicin. The process involves two stages: elimination of 2-propenesulfenic acid from the amino acid unit (with dehydroalanine as a byproduct), and then condensation of two of the sulfenic acid molecules. Reaction scheme for the conversion: cysteine → alliin → allicin
The major volatile compounds responsible for garlic breath are allyl methyl sulfide, allyl methyl disulfide, allyl mercaptan, diallyl disulfide, dimethyl disulfide and methyl mercaptan, along with minor amounts of dimethyl selenide. [1] [2] [3] Various other sulfur compounds are also produced when allicin in garlic is broken down in the stomach ...
