Compounds containing sulfur. Sulfur atoms (s) are present in the chemical structure of these compounds, therefore their name. When garlic is sliced, crushed, or crushed, sulfur compounds are emitted. When alliin (an inactive, odorless molecule in garlic) comes into touch with an enzyme, it transforms into allicin, the molecule that gives garlic its distinctive scent. Allicin is then converted into diallyl sulfide, diallyl disulfide, and ajoene, among other sulfur compounds. These substances are primarily responsible for preventing certain cancer cells from growing and thereby protecting the body from possible carcinogens. It should be mentioned that allicin is destroyed during the manufacturing of garlic pills, which means that eating garlic tablets will not allow you to consume the active chemicals that are helpful to your health.
