There are two different structures of malic acid, an L-isomer and a D-isomer. The only difference between the two is that they rotate the light shining on them in two different directions.
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 it in just the same way as it does for L-malic acid. It is part of the Krebs cycle.

Is that mean dl- malic acid and malic acid are the same thingscan you use dl- malic acid dl- hydroxysuccinic acid for gallbladder detox?
Before you do any type of gallbladder detox, you would need to speak with your doctor. DL malic acid and DL hydoxysuccinic acid are things you would want to run by your doctor for sure. Malic acid is found in fruit, but you want to make sure it doesn't interact with current medications.
What is differnece in dl-malic acid and malic acid?
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.
Is malic acid a natural product?
There are two forms of malic acid; the L-isomer is found naturally in most fruits and many vegetables in varying amounts. Of the total acid content in apples, 90-98% is L-malic acid. Malic acid can also be produced synthetically from maleic anhydride. It is impossible to choose whether natural L-malic acid or the unnatural D-malic acid isomer is formed during synthesis so a mixture of the two is formed, often called DL-malic acid. It is most likely that if malic acid is used as an additive, it is the synthetic DL-malic acid. The body metabolises the two forms in exactly the same way.
Is malic acid found in apple juice good or bad for your child?
Malic acid found naturally in apple juice will be the L-isomer exclusively. This is the natural form of malic acid. Synthetic malic acid - the acid which has been produced rather than extracted - is a mixture of the two isomers, named D-malic acid and L-malic acid. Since it is impossible to separate the two, the mixture is often referred to as DL-malic acid. Natural L-malic acid has been declared suitable for all ages. D-malic acid should not be given to very young infants because they have not yet developed the enzymes to utilise malic acid in the Krebs cycle (which is how older humans metabolise it). If the apple juice is marketed for infants, it will not have D-malic acid added to it and will therefore be safe. Malic acid which has been used as an additive will usually have the E-number 296 and is likely to be synthetic. Any malic acid can be considered as a flavour enhancer or a preservative and is neither good nor bad for your child so long as they are older than infant age and brush their teeth regularly.
What is the difference between malic acid and citric acid?
Malic acid is an acid that is tart and produced naturally in unripe fruits. Citric acid is naturally in the juice of sour fruits and commercially made. Commercial citric acid is made from fermented sugar.
Do tomatoes have malic acid?
the answer is yes. tomatoes do contain Malic acid.
Do apples contain malic acid?
Of all the acid in green apples, 90% of it will be malic acid. This naturally-occuring acid will be found exclusively in the form of the L-isomer, whereas synthetic malic acid is made up of both L- and D-malic acid
What acid is present in apple?
Malic acid, also shown as E296 when used as an additive ingredient
What fruit has the most malic acid?
Apples contain the most malic acid as a percentage of total fruit acid content. The amount of malic acid in apples as a percentage of the total acid is 94-98%
Where is malic acid found?
Malic Acid is found in mostly green apples, grapes and wine .
Is malic acid organic or inorganic?
All acids with a general formula of R-COOH are organic acids from a chemistry point of view. Malic acid can be extracted from apples or produced synthetically from butane gas. From a food legislation point of view: If the malic acid is extracted from an organic apple, it counts as organic malic acid. If the malic acid is extracted from an apple which has been treated with chemical pesticides or fertilisers, it is inorganic malic acid.
Is Malic Acid bad for you?
Nope its not. The pleasant, refreshing experience of biting into a juicy apple or cherry is partly caused by Malic acid, Malic acid is found mostly in unripe fruits. But it should not taken a lot in 1 dose!.
