1. With silk from feed silkworm as raw materials, refined through biological process to get the amino acid mixture (fine silk), more than 85% of whose content are alanine, serine and glycine, is a functionally prominent nutrient with higher nutritional value.
2. Not only can glycin and serine be used as the essential materials of synthesizing protein in organism, but also as the predecessor of synthesizing the glutathione (GSH, SSG), which has certain preventive action on heart disease and cancer. Meanwhile, the glycin also has the detoxication effects for some aromatics which can cause cancer. The rich alanine also helps promoting the metabolism of alcohol in human body and protecting liver. Moreover, tyrosine has obvious effect on preventing the old from Alzheimer disease.
3. Silk protein is very easy to permeate the derma layer of skin and get absorbed, nurturing skin as well. Due to its action in the enzyme metabolism, silk amino acid can keep and adjust moisture, prevent skin from ultraviolet radiation, restrain splash generation, facilitate anti-aging for skin.
