Malicacid (Malicacid), also known as hydroxysuccinic acid, because there is an asymmetric carbon atom, there are three kinds of malic acid: L-malic acid, D-malic acid, DL-malic acid.
L-malic acid is a product of the tricarboxylic acid cycle in the human body, so the human body can only metabolize L-malic acid. L-malic acid occurs naturally in apples, grapes, lemons and other fruits. Such as extraction from the fruit, low content, high cost, can not be industrialized mass production.
The catalytic synthesis of fumaric acid (fumaric acid) can only produce DL-malic acid, because the human body can not metabolize DL-malic acid, so although DL-malic acid is allowed as a food additive in Europe and the United States, people always feel unsafe. The malic acid produced by microbial methods is all L-malic acid, so the malic acid used now is all produced by microorganisms, and the malic acid used in food, medicine, etc., basically replaces DL-malic acid with L-malic acid.
