Applications
Medicine:
L-alanine is an important raw material for the synthesis of VB6. It is one of the components of the nutrient supplement amino acid nutritional infusion.

Cysteine is mainly used in liver drugs, antidotes, expectorants and other medical drugs.

Cysteine and its derivatives can be used for detoxification of liver poisoning, antipyretic analgesia, ulcer treatment, fatigue recovery, infusion and comprehensive amino acid preparations, especially for expectorant; Treatment of bronchitis and phlegm.

Amino acid injection-800 with L-alanine as the main component is mainly used to treat liver and brain diseases, and promote the rapid recovery of patients with liver coma. At the same time, it is also a good medicine for diuresis.

Food additives:

(1) It can improve the nutritional value of food, in all kinds of food and beverages, such as bread, ice cream, fruit tea, dairy products, carbonated drinks, ice cream, etc. Adding 0.1 ~ 1% alanine can significantly improve the protein utilization rate in food and beverage. Because alanine can be directly absorbed by cells, it can quickly recover fatigue and cheer up after drinking.

(2) Improving the taste of synthetic sweetener can increase the sweetness and reduce the dosage. Adding 1 ~ 10% alanine to the compound sweetener can improve the sweetness, soften the sweetness, like the natural sweetener, and improve the taste.

Alanine is also one of the raw materials for the synthesis of high sweetness alitame (l-aspartyl-d-alanine amide, 600 times the sweetness of sucrose).

Biochemical research. Tissue culture. Liver function measurement.

Used as flavor enhancer. It can increase the seasoning effect of seasoning; It can also be used as sour correction agent to improve the sour taste of organic acids.

β- Alanine is used as an additive in electroless plating and electroplating, and also in the preparation of electroplating corrosion inhibitor.
