Description: Quercetin is a flavonoid found in a wide variety of fruits, vegetables, and plants. This compound is known for its powerful antioxidant properties, which help combat damage caused by free radicals in the body. Quercetin belongs to the class of flavonoids, which are natural pigments responsible for the vibrant colors in many plants. In addition to its antioxidant capacity, quercetin has also been associated with anti-inflammatory, antihistaminic effects, and potential benefits for cardiovascular health. Its water solubility is limited, which may influence its absorption and bioavailability in the body. This flavonoid is found in foods such as onions, apples, grapes, berries, and tea, making it an important component of a healthy diet. Research on quercetin has grown in recent decades, highlighting its potential in the prevention of chronic diseases and its role in modulating various biological functions. Its relevance in biochemistry is due to its interaction with multiple metabolic pathways and its ability to influence gene expression, making it a subject of study in the fields of bioinformatics and pharmacology.
History: Quercetin was first identified in 1857 by the German chemist Johann Friedrich August von Braconnot, who isolated it from the bark of a tree. Since then, its chemical structure was determined in 1935, allowing for a greater understanding of its properties and functions. Throughout the 20th century, research on quercetin expanded, especially in the context of nutrition and health, as its potential as a bioactive compound was recognized.
Uses: Quercetin is primarily used as a dietary supplement due to its antioxidant and anti-inflammatory properties. Its use has been studied in the treatment of allergies, cardiovascular diseases, and as a complement in cancer therapy. Additionally, its potential to enhance physical performance and muscle recovery in athletes is being researched.
Examples: A practical example of quercetin use is its inclusion in supplements for individuals suffering from seasonal allergies, as it may help reduce symptoms by acting as a natural antihistamine. Another example is its use in formulations for cardiovascular health products, where its antioxidant properties are sought to improve heart health.
