Applications
- Mixed amino acids, a kind of highly practical nutrient substance with higher nutritive value, is produced through biochemistry technology which adopts the raw material of mulberry silk in which alanine, serine and glycine account for more than 83%.
- Glycine and Serine of silk essence are raw materials to synthesize protein in organisms, and are also precursors for synthesis of glutathione, which has a preventive effect on cardiovascular diseases, cancer and aging; Glycine also has an antidotal action on the detoxication of aromatic compounds which can cause cancer; alanine promotes the alcohol metabolism, protects the liver and prevents people from being drunk; tyrosine has a good effect on preventing senile dementia.
- Silk essence can easily impenetrate into the dermis layer of skin, be quickly absorbed by the skin, and takes part in enzyme activities, which obtains the actions of humidity, moisturizing, UV radiation, inhibiting melanin production, preventing skin aging and nourishing the skin.
