Other important examples are 1,2-benzoquinone (ortho-quinone), 1,4-naphthoquinone and 9,10-anthraquinone. The name is derived from that of quinic acid (with the suffix "-one" indicating a ketone), since it is one of the compounds obtained upon oxidation of quinic acid. [ 4 ]
Quinine is an alkaloid, a naturally occurring chemical compound. [5] How it works as a medicine is not entirely clear. [5] Quinine was first isolated in 1820 from the bark of a cinchona tree, which is native to Peru, [5] [9] [10] and its molecular formula was determined by Adolph Strecker in 1854. [11]
In the United States, the US Food and Drug Administration (FDA) limits the quinine content in tonic water to 83 ppm [8] (83 mg per liter), while the daily therapeutic dose of quinine is in the range of 500–1000 mg, [9] and 10 mg/kg every eight hours for effective malaria prevention (2,100 mg daily for a 70-kilogram (150 lb) adult).

When he was drinking, he stopped after a couple and also prioritized lighter options like wine over beer. While beer typically contains around 200 calories per serving, a small glass of white wine ...
Coenzyme Q 10 (CoQ 10 / ˌ k oʊ k j uː ˈ t ɛ n /), also known as ubiquinone, is a naturally occurring biochemical cofactor (coenzyme) and an antioxidant produced by the human body. [1] [2] [3] It can also be obtained from dietary sources, such as meat, fish, seed oils, vegetables, and dietary supplements.
