 Application characteristics: 1. With silk from feed silkworm as raw materials,refined through biological process to get the mixed amino acid(silk essence), more than 85% of whose content are alanine, serineand glycin, is a functionally prominent nutrient with highernutritional value. 2. Glycin and serine can not only be used as theessential materials of synthesizing protein in organism, but alsobe used as the predecessor of synthesizing the glutathione (GSH,SSG), which has certain preventive actions on heart disease andcancer. Meanwhile, the glycin also has the detoxication effects forsome aromatics which can cause cancer. The rich alanine also helpspromoting the metabolism of alcohol in human body and protectingliver. Moreover, tyrosine has obvious effect on preventing the oldfrom Alzheimer disease. 3.  Silk amino acid is very easy to permeate the dermalayer of skin and get absorbed, nurturing skin as well. Due to itsaction in the enzyme metabolism, silk amino acid can keep andadjust moisture, prevent skin from ultraviolet radiation, restrainsplash generation, facilitate anti-aging for skin.
