    Study Notes

    Organosulfur Compounds

    • Organosulfur compounds are found in the Allium and Brassica families of vegetables.
    • These compounds have non-antioxidant effects as nutraceutical agents, including anti-inflammatory, antibacterial, and antiviral effects.

    Sources of Organosulfur Compounds

    • Garlic and onion are common foods that contain organosulfur compounds.
    • Cruciferous vegetables, such as broccoli and cauliflower, are also sources of organosulfur compounds.
    • Protein-rich foods like meat, fish, and poultry are dietary sources of sulfur.

    Importance of Organosulfur Compounds

    • Certain organosulfur compounds in garlic and onion have antibacterial, antiviral, and antifungal properties.
    • Organosulfur compounds can be useful in the prophylaxis and treatment of neurodegenerative diseases, diabetes, and respiratory diseases.
    • These compounds are needed as cofactors for enzymes such as glutathione peroxidase and thioredoxin reductase.
    • The mineral sulfur is a component of organosulfur compounds.

    Effects of Processing on Organosulfur Compounds

    • The levels of organosulfur compounds are affected during fermentation and packing steps, with a decrease in levels during these processes.
    • Glucosinolates in cruciferous vegetables break down to form compounds with anti-inflammatory and antioxidant effects.

    Other Facts

    • The recommended daily intake of garlic cloves is not specified.
    • Allicin, a compound in garlic, forms ajoene when extracted with oil.
