process of deriving
adenosine triphosphate (ATP; the energy currency that runs the body) from food.
Where is it found?
Malic acid is found in a wide variety of fruits and vegetables, but the richest source is apples, which is why malic acid is sometimes referred to as “apple acid.”

Who is likely to be deficient?
A deficiency in humans is unlikely, since the body can produce malic acid.
