Malic acid is a dicarboxylic acid commonly found in fruits such as apples. Its chemical formula is C4H6O5. When pronounced, the first syllable is pronounced using the long "a" sound /ˈmeɪlɪk/, which is followed by the short "i" sound /ˈæsɪd/. The second syllable is pronounced with a silent "c", giving way to the long "a" sound /ˈseɪd/. Using the International Phonetic Alphabet, the word malic acid can be spelled out as /ˈmeɪlɪk ˈæsɪd/.
Malic acid is a naturally occurring organic compound with the molecular formula C4H6O5. It belongs to the class of chemicals known as hydroxy acids, having both a carboxylic acid and a hydroxyl group in its structure. Malic acid is found naturally in many fruits, particularly apples, and is responsible for their tart taste. It is also present in other fruits such as grapes, cherries, and strawberries, as well as in some vegetables.
In terms of its chemical properties, malic acid is a white crystalline solid that is highly soluble in water. It has a distinct sour taste and is often used as a food additive for its acidity and flavor enhancement. It is categorized as a non-toxic substance and is generally recognized as safe (GRAS) by regulatory authorities.
Malic acid is widely used in the food and beverage industry as a flavor enhancer, pH regulator, and preservative. It contributes to the sourness and tangy taste in various edible products, including candy, carbonated drinks, sauces, salad dressings, and jams. It is also utilized in the production of cosmetic and personal care products, as well as in pharmaceutical preparations.
Moreover, malic acid has been studied for its potential health benefits. It is believed to have antioxidant properties, which help neutralize harmful free radicals in the body. Additionally, it is involved in the Krebs cycle (citric acid cycle) - an important series of chemical reactions in cellular respiration that generates energy for the body.
Overall, malic acid is a versatile organic compound widely utilized in various applications due to its acidity, flavor profile, and potential health benefits.

The word "malic" in "malic acid" originates from the Latin word "malum", which means "apple". This is due to the fact that malic acid was first isolated from apple juice in 1785 by Carl Wilhelm Scheele, a Swedish chemist. It is the primary acid present in apples and gives them their characteristic tart taste. The acid was named "malic" to reflect its association with apples.
