About Malic Acid
Malic acid, also known as 2-hydroxysuccinic acid, has strong hygroscopicity and is easily soluble in water and ethanol. It is mainly used in the food industry and the pharmaceutical industry.
Since there is an asymmetric carbon atom in the malic acid molecule, there are two stereoisomers. In nature, it exists in three forms, namely D-malic acid, L-malic acid and DL-malic acid.
Naturally occurring malic acid is L-shaped, and it is present in almost all fruits, with the most in pome fruit.
Its chemical formula is C4H6O5, and CAS number is 6915-15-7.
MS-based technical means can realize the qualitative and quantitative analysis of malic acid.

Technical Route of Targeted Metabolomics of Malic Acid
|Plants, yeasts, microorganisms, etc.|
Serum, plasma, urine, bile, bile acid, etc.
Cells, liver, brain tissue and other animal tissues and feces, etc.
There is no restriction on plant varieties. For varieties with special requirements or rare varieties, please contact our staff for more information.
|Plant root / stem / leaf / fruit / seed > 200 mg fresh weight, freeze-dried sample > 0.5 g|
Cells / microorganisms / cell supernatant / culture medium supernatant: the number of cells or bacteria > 107, supernatant > 2 ml
Serum / plasma / urine / ruminal fluid / cerebrospinal fluid / amniotic fluid and other homogeneous liquid samples > 200 µl.
(Hemolysis should be avoided. Cerebrospinal fluid can be as low as 100 µl.)
Animal tissue / feces related samples > 200mg / sample
For other sample types, please consult technical support or sales.
|Sample mixed and repeat|
|In order to ensure the accuracy of the samples and reduce systematic errors during sampling, it is necessary to select more than 3 materials with the same condition for each sample. |
※ The same condition refers to the same period, basically the same phenotype, and the same part.
It is recommended that prepare more than 6 biological replicates.
|Storage and transportation|
|Quick-frozen preservation with liquid nitrogen can minimize the leakage time of plant samples at room temperature, and store it at -80℃.|
Dry ice transportation (about 3~4 kg dry ice is consumed every day, please use sufficient dry ice for transportation).
