These groups are -COOH.
Malic acid, also shown as E296 when used as an additive ingredient
Bananas contain mainly citric acid and malic acid. However, the majority of the acid in bananas is malic acid.
Malic acid is the predominant organic acid in apples. It is responsible for the tart flavor in apples.
Malic acid is commonly found in melons, contributing to their characteristic tangy flavor.
Plums contain citric acid which is responsible for the tart flavor in the fruit.

malic
Malic acid is present in apple juice.
Two acids present in tomato are citric acid and malic acid.
Malic acid can be produced in a pure form by crystallising it out of water when it has been made synthetically from maleic anhydride, which in turn is made simply from butane gas. This reaction process leads to a mixture of the two malic acid isomers. To purify the natural form of L-malic acid, it is necessary to remove it from apples or other fruits where malic acid is present in a high concentration. This can be done by fractionated distillation. Green apples are best for this since 90% of the acid present in them is malic acid.
Malic Acid, Citric acid, Isocitric Acid, Succinic Acid and Fumaric Acid.
Ascorbic acid is present in tomatoes.Oxalic acid, though, is the main acid in tomatoes.Tomatoes contain citric, malic, oxalic, succinic, glycolic, tartaric, phosphoric, hydrochloric, sulphuric, fumaric, ascorbic, pyrrolidinonecarboxylic and galacturonic acids. The most abundant are citric and malic acids.

There are two different structures of malic acid, an L-isomer and a D-isomer. These two molecules are identical like your left and right hands. While they have the same atoms and bonds, they are not necessarily interchangeable, just as you cannot fit your left hand in a right hand-shaped hole. L-Malic acid is produced naturally in fruits. 90% of the acid in apples is malic acid. When malic acid is produced synthetically, a mixture of the two isomers is obtained which is called DL-malic acid (because it contains both D- and L-malic acid). When you eat DL-malic acid, your body digests the L-malic acid normally (it is part of the Kreb's cycle), but the D-malic acid is excreted in the urine. A 1967 study by the WHO shows evidence that D-malic acid is toxic and causes renal damage. When purchasing malic acid, if it is called "malic acid" it is likely DL-malic acid. If the natural form is desired, purchase specifically L-malic acid.
