    It is an important biologically active substance in the organism, and an important intermediate product in the process of biochemical metabolism from L-tyrosine to catechol or melanin. It has a diphenolic structure and is unstable in nature. It is easily oxidized and deteriorated by oxygen in the air. Its aqueous solution will turn black after being stored for a long time, and high temperature and other factors can accelerate its change. Dopamine is an important neurotransmitter. Levodopa can pass through the blood-brain barrier and decarboxylate to form this substance in the brain tissue, thereby increasing the content of dopamine in the brain tissue for the purpose of treatment. Our company uses microbial enzymatic technology to convert different substrates into levodopa using enzymes in the metabolic pathway.
