* A larva repeats the casting off during the growth process as eating the mulberry leaves. It produces cocoon as generating the silk thread through the mouth to be the imago.
* That silk thread is silk. The silk mainly comprises Fibroin and Sericin. These proteins are hydrolyzed and produced as the peptide containing 18 kinds of amino acids. The silk peptide is the peptide binding of amino acids. In particular, the silk peptide of SIL-Q Two Plus mainly comprises the free amino acids.

* The dietary proteins and amino acids have impact on the body through various mechanisms in the body. Single amino acid or multiple amino acids have impact on the mechanisms including absorption in the intestines, appetite, excretion and deactivation of hormones, induction and restriction of enzymes and synthesis and decomposition of nucleid acid. It can help the sound growth and development of the body and maintenance of healthy life
