Sericin, Firbroin
Silk emitted by the silkworm consists of two main proteins, sericin and fibroin, fibroin being the structural center of the silk, and serecin being the sticky material surrounding it. Fibroin is made up of the amino acids Gly-Ser-Gly-Ala-Gly-Ala and forms beta pleated sheets. Hydrogen bonds form between chains, and side chains form above and below the plane of the hydrogen bond network.
The sericin is dissolved in hot water leaving the fibroin to be made into thread, either by unravelling and winding many strands into a thread or the entire cocoon is shredded and the fibers spun into thread.
