    Lemons and other citrus fruits contain amounts of different chemicals and are thought to have some health benefits. They contain a terpene called limonene which gives their characteristic lemon smell and taste. Lemons contain significant amounts of citric acid; this is why they have a low pH and a sour taste. They also famously contain Vitamin C (Ascorbic acid) which is essential to human health. 100 milliliters of lemon juice contains approximately 50 milligrams of Vitamin C (55% of the recommended daily value) and 5 grams of citric acid.

    Some sources state that lemons contain unique flavonoid compounds that have antioxidant and anti-cancer properties.[3] These may be able to deter cell growth in cancers. Limonins found in lemons could also be anti-carcinogens.

    Because of its high Vitamin C content, lemon has been touted in alternative medicine as a tonic for the digestive system, immune system, and skin.[citation needed]

    according to the paragrah above

    lemon juice is mainly cosist of water(H2O), citric acid(C6H8O7) and vitamin C(C6H8O6)
