Succinic acid, also known as succinic acid, is widely present in all plant and animal tissues, was first extracted from amber, is an intermediate in the citric acid cycle, and plays an important role in the production of energy in cells. Succinate, or succinate, is widely used in the agricultural, food and pharmaceutical industries due to its low toxicity. Succinic acid is catalyzed by enzyme reagent to form colored substance with color developer. The maximum absorption is at 555 nm. The content of succinic acid in samples can be calculated by measuring OD value and standard curve at 555 nm.
