As a kind of chemical substances, the general formula of aspartic acid determines that they have some basic properties. First of all, aspartic acid is a small molecule, and its molecular weight does not exceed 1000. In addition, the melting point of aspartic acid is above 230℃, and there is no exact melting point, and it decomposes and releases CO2； when melting. Can be dissolved in strong acid and strong alkali solution; At room temperature, aspartic acid is slightly soluble in water, hardly soluble in ethanol and ether, and soluble in boiling water. Can combine with acid to form salt, and can also combine with alkali to form salt. From the structure of aspartic acid, it can be seen that aspartic acid has optical activity because there are asymmetric carbon atoms in its molecule. At the same time, due to the different arrangement positions in space, the aspartic acid that constitutes protein is L-shaped.

Biosynthesis:

For mammals, aspartic acid is not necessary because it can be produced from oxaloacetic acid by transamination. For plants and microorganisms, aspartic acid is the raw material of several amino acids, including four essential ones: methionine, threonine, isoleucine and lysine. The conversion from aspartic acid to those amino acids begins with the conversion of aspartic acid to its "semialdehyde". Asparagine is produced by transamination of aspartic acid;

Toxicological data:

1, other multi-dose toxicity: oral LD of rats: 6063 mg/kg/7d-c;

2, causing inflammation of eyes and skin.

Ecological data:

It is slightly harmful to water. Do not let undiluted or large quantities of products enter groundwater, waterways or sewage systems.
