What does malic mean?
Malic is an adjective used primarily in chemistry and biochemistry to describe malic acid, its derivatives, or processes involving it. Malic acid is a naturally occurring organic acid present in many fruits, especially apples, and is responsible for part of their sour or tart taste. Because of this association, the term is sometimes used in food science when discussing fruit acidity and ripening. In biological contexts, “malic” can refer to enzymes and metabolic pathways that create, break down, or transport malic acid. The word comes through French from Latin malum, meaning “apple,” reflecting the acid’s historical association with fruit. Although malic acid is familiar to many people through its presence in apples, the adjective itself belongs mainly to technical and scientific vocabulary rather than everyday speech.
adjectiveRelating to or derived from malic acid, an organic acid found especially in apples and other fruits. In biochemical contexts, it may also refer to substances or processes involving malic acid.
- Relating to malic acid or its salts and esters.
- In biochemistry, relating to the metabolism or conversion of malic acid.
"The concentration of malic acid contributes to the tartness of the fruit."
"Malic acid gives apples much of their characteristic tartness."
"The malic enzyme helps regulate metabolism in living cells."
Malic is the word behind the tartness of a green apple: malic acid is one of the main acids responsible for its distinctive sour flavor.

Where does malic come from?
The word is an English borrowing from French malique, which was used in the expression acide malique, “malic acid.” The French adjective ultimately derives from Latin malum, meaning “apple,” reflecting the acid’s presence in fruit. The related Latin malus meant “apple tree,” while malate refers chemically to a salt or ester derived from malic acid.
