Sericin

 

(also silk gum), a viscous protein of natural silk constituting approximately one-third of the silk’s weight. It is characterized by a high content of the amino acid serine (up to 40 percent). Sericin cements the filaments of fibroin, the other protein of silk. In contrast to fibroin, sericin is soluble in hot water and alkaline solutions.
