🧄 Allicin is often considered one of garlic’s most biologically active compounds.
But allicin isn’t where the story begins.
In fresh garlic, the predominant sulfur compound is alliin. When garlic is crushed, chewed, or exposed to the right conditions, the enzyme alliinase converts alliin into allicin, a transformation that occurs naturally and rapidly.
🔬This relationship between alliin and allicin is one of the most interesting aspects of garlic chemistry.
While allicin receives much of the attention in the scientific literature, alliin serves as the stable precursor from which allicin is formed. Understanding this pathway helps explain how garlic’s sulfur compounds interact and transform within the body, and why the alliin–allicin conversion pathway remains central to discussions around garlic standardisation.
