Sulfonamides are the earliest type of artificially synthesized broad-spectrum antibacterial drugs used. The minimum effective concentration in the blood is 5 mg/100 ml, and 10-15 mg/100 ml is required for severe infections. They are effective against most Gram-positive bacteria and some Gram-negative bacteria. Sulfonamides exert their antibacterial effects by competing with PABA for dihydrofolate synthetase, hindering the synthesis of folate in sensitive bacteria. Sulfonamides have no effect on already synthesized folic acid, so the effect occurs slowly. Bacteria that can utilize exogenous folic acid are not sensitive to sulfonamides. Livestock and poultry cells can directly utilize folic acid, so they are not easily affected by sulfonamides blocking folic acid synthesis.

Extract from the above information

This product is an anti-anemia drug. Vitamin B12 participates in methyl conversion and folic acid metabolism in the body, and promotes the conversion of 5-methyltetrahydrofolate into tetrahydrofolate. When it is deficient, it leads to DNA synthesis disorders and affects the maturation of red blood cells. This product also promotes the conversion of methylmalonic acid into succinic acid and participates in the tricarboxylic acid cycle. This effect is related to the synthesis of nerve myelin lipids and the maintenance of the integrity of myelinated nerve fiber function. The nerve damage caused by vitamin B12 deficiency may be related to this.

It is one of the essential amino acids for the human body and provides methyl groups in the process of synthesizing choline in the body.

It is a precursor substance for methyl groups and an important component in the synthesis of choline. It participates in the synthesis of lipoproteins by promoting the synthesis of phospholipids. Intrahepatic fat is transported to extrahepatic tissues in the form of synthesized lipoproteins for utilization or storage.
