Uses:
1. Applications in biomedicine.
In terms of medicine, L-Homocystine has a wide range of detoxification effects against poisons such as formic acid, acetic acid, carbon tetrachloride, and alcohol because of its cohesion in vivo, and can maintain the activity of thiolase in keratin production. L-Homocystine hydrochloride has Uses that can restore liver function, and also has a certain therapeutic effect on serum sickness, antimony and radiopharmaceutical poisoning.
Derivatives of L-Homocystine hydrochloride can be used in medicine, such as acetyl L-Homocystine hydrochloride is a respiratory soluble expectorant, through its special SH group, can quickly make the mucin in the spot fluid Breaking, the viscosity of the mucus drops rapidly, so that the sputum can be quickly coughed or aspirated in just a few minutes. Because of its function, it can quickly treat acute and chronic bronchitis, asthma, dilation, tuberculosis, pneumonia, emphysema, etc. caused by thick sputum, breathing difficulties and other diseases. At the same time, L-Homocystine hydrochloride and its derivatives have anti-inflammatory, analgesic, and inhibitory effects on bacterial and cancer cell growth.
2. Application in the food industry
In the food industry, co-heating L-Homocystine with five-carbon or six-carbon sugars can produce the aroma of meat, while adding hemicarpalamic acid to processed corn products can increase the aroma of corn by 10-40 times. Therefore, hemibrachiine is widely used in meat products, dairy products, bread and other products, which can enhance food stability, improve the stability of ascorbic acid and slow down the auto-oxidation of fat, so it has positive effects on food storage and aroma. Impact.
Adding L-Homocystine to natural juice can prevent the oxidation of vitamins and prevent the juice from turning brown, and prolong the storage time of natural juice. Japan often adds L-Homocystine to milk to prevent milk powder from spoiling. Regular drinking can prolong life.
3. Application in physical cosmetics
L-Homocystine has the function of preventing biological aging. The introduction of L-Homocystine into cosmetics can prevent skin aging, make the skin rosy, and as a hair conditioner, it can make hairstyles long-lasting.
