Sericin is a globular protein isolated from silkworm cocoons. It has cognitive enhancement and pain-relieving properties. Additionally, Sericin serves as a cryoprotectant, potentially replacing fetal bovine serum or dimethyl sulfoxide (DMSO). It helps reduce oxidative stress and reactive oxygen species (ROS). Sericin aids in wound repair by promoting collagen production and exhibits activities such as antioxidant, antidiabetic, antihyperlipidemic, anti-inflammatory, moisturizing, wound healing promotion, antibacterial, and antitumor effects.
