In the realm of advanced biomaterials, few substances have captured my interest as thoroughly as silk fibroin peptide. Derived from the domesticated *Bombyx mori* silkworm, this fascinating protein-based biomacromolecule has transitioned from a simple textile fiber to a cornerstone of modern material science. My journey into understanding this compound began with a curiosity about how nature-derived proteins could be manipulated for structural and functional applications.
Understanding the Source: Fibroin vs. Sericin
To apprec by S Liu·2023·Cited by 25—Silk fibroin (SF) is a protein-based biomacromolecule, which is widely used in biomedical fields and drug delivery systems. As the hydrolysate of silk fibroin, Read more iate the utility of this substance, one must first distinguish between the two primary proteins found in Fibroin has good mechanical properties with higher tensile strengthcompared to other natural fibers, and better hardness than other silk fibers [7], [8].Read more silk. Raw silk is composed of fibroin, the main structural protein, and sericin, which acts as a supportive glue. While sericin holds the fiber together in its natural state, it is the fibroin that gives silk its characteristic strength and flexibility.
When we discuss silk fibroin peptide, we are looking at small protein fragments obtained by the hydrolysis of mulberry silk protein. These fragments possess lower molecular weights compared to the original silk protein, which significantly improves their solubility and film-forming capabilities.

* Production: The material is often processed through pancreatin hydrolysis of silk fibroin active peptide to achieve the desired chain length and bioactivity.
* Composite Potential: Research into silk fibroin (SF)/polymer composite materials highlights the ongoing efforts to overcome issues related to miscibility, aiming to maintain the high tensile strength of the natural fiber.
Biological Interactions and Future Horizons
The versatility of silk fibroin proteins (SFP) extends into various experimental fields. For instance, studies have shown that SFP extracted from silk cocoons has antiproliferative effects on lung cancer cells in both *in vivo* and *in vitro* models.
