Introduction

L-methionine is an amino acid that is one of the building blocks of protein in the human body.

 

L-Methionine is a white crystalline solid that is soluble in water and alcohol-based solvents. It has a high solubility and can be dissolved and diluted under the right conditions.

 

L-methionine has many important biological functions. It is one of the amino acids necessary for the body to synthesize proteins, as well as for the synthesis of muscle tissue and other tissues in the body. L-methionine is also involved in biochemical reactions in the body to maintain normal metabolism and health.

It is used as a nutritional supplement to improve muscle growth and repair, boost immune system function and promote wound healing, among other things.

 

L-methionine can be prepared by synthesis and extraction. Synthesis methods include enzyme-catalyzed reactions, chemical synthesis, etc. The extraction method can be obtained from the natural protein.

 

When using L-methionine, the following safety information should be noted:

- Avoid contact with skin and eyes, and rinse immediately with plenty of water if contact occurs.

- Avoid ingestion and inhalation, and seek immediate medical attention if ingested or aspirated.

- Store tightly sealed and in a cool, dry place, away from fire and flammable materials.

- Follow the relevant safety procedures and measures when using, storing, and handling L-methionine.
