Its beneficial widespread effect on health is attributed to sulphur compounds and particularly to thiosulfinates. Odorless and stable, alliin is the most abundant sulfur compound in whole, unbruised Garlic. When the clove of garlic is cut or crushed, the enzyme alliinase is released from its compartment and transforms S-allyl-L-cysteine sulfoxide or alliin into diallyl thiosulfinate allicin, the characteristic compound of garlic flavor. This very unstable thiosulfinate is rapidly degraded to related organosulfur compounds. Allicin is often thought of as the "active ingredient" in Garlic, and has been the subject of numerous scientific studies, but its a fairly unstable compound that likes to react with itself.

蒜氨酸(S-烯丙基-L-半胱氨酸亚砜，alliin)是完整、未受损大蒜里面含量最丰富的硫化物，并且非常稳定，它存在于大蒜的细胞质里；当细胞受损时，蒜氨酸酶从细胞液向细胞质释放，蒜氨酸和蒜氨酸酶接触被迅速转化为一系列新的化合物—蒜辣素及其相似物，蒜辣素(双烯丙基硫代亚磺酸酯，allicin)被认为是大蒜中最重要的活性成分，但它相当不稳定，易于自身反应。

Considering our present advanced state of culture, and how the Torch of Science has now been brandished and borne about, with more or less effect, for five thousand years and upwards; how, in these times especially, not only the Torch still burns, and perhaps more fiercely than ever, but innumerable Rushlights, and Sulphur-matches, kindled thereat, are also glancing in every direction, so that not the smallest cranny or dog-hole in Nature or Art can remain unilluminated,--it might strike the reflective mind with some surprise that hitherto little or nothing of a fundamental character, whether in the way of Philosophy or History, has been written on the subject of Clothes.

考虑到我们现在的文化先进的国家，如何科学的火炬已经挥舞并承担有关，有或多或少的影响，为五千年及以上；如何，特别是在这些时候，不仅是火炬仍在燃烧，并也许比以往更激烈，但无数Rushlights和硫火柴，点燃了会场，也是在各个方向瞥了一眼，使不上最小的狗或裂隙中自然或艺术孔可以保持unilluminated，-它可能罢工的反思一些惊喜，到目前为止很少或根本没有字符，不论是哲学还是历史的方式，心，一直写在服装的主题。
