The comprehensive research of Silk Fibroin

Silk fibroin is a natural protein obtained from the fibers of silkworms and spiders. It has been the subject of extensive research due to its unique properties and potential applications in various fields, including medicine, textiles, and materials science. Here’s a comprehensive overview of silk fibroin:

  1. Structure and Composition:

Silk fibroin is primarily composed of proteins, with the amino acid sequence dominated by glycine, alanine, and serine.
It consists of heavy chains (H-chains) and light chains (L-chains) linked by disulfide bonds, forming a complex structure.

  1. Production:

Silk fibroin is typically harvested from silkworms or, in some cases, produced by genetically engineered bacteria, yeast, or plants.
The process of silk production involves boiling silkworm cocoons, which allows the extraction of the fibroin protein.
