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.

What is the monomer of the polymer silk?
Silk is actually a polymer made by protein complexes in the repeating fashion.
Is silk a noun?

Does silk shrink in the dryer?
no because it has protein and fiber made by a silk worms cacoon, so it does not shrink..
What is a silk protein?
Protein found in silk,a strong,soft,lustrous fibre made of fibroin, a structural protein consisting almost entirely of stacked antiparellel beta plated sheets.
Why silk smells like burning hair?
Silk is made from natural protein fibers, similar to human hair. When silk is burned, it releases a scent that is similar to burning hair due to the breakdown of the protein structure.
