sericin การใช้

• It consists mainly of two proteins, fibroin and sericin.
• Sericin has also been used in medicine and cosmetics.
• The cocoons are first boiled to loosen the sericin holding the filaments together and remove the silkworm.
• Sericin C also contains the amino acids present in B, along with the addition of proline.
• Sericin C is the innermost layer, the layer that comes closest to and is adjacent to fibroin.
• They spin their cocoon around themselves by extruding liquid silk that's covered with a tacky sealant called sericin.
• There are also three different types of sericin, which make up the layers found on top of the fibrin.
• Sericin B, composed the middle layer and is nearly the same as sericin A, but also contains tryptophan.
• Sericin B, composed the middle layer and is nearly the same as sericin A, but also contains tryptophan.
• Liquid silk is coated in sericin, a water-soluble protective gum, and solidifies on contact with the air.
• Also insoluble in water, sericin C can be separated from the fibroin via the addition of a hot, weak acid.
• The presence or sericin increases hydroxyproline in the stratum corneum, which in turn, decrease skin impedance, thus increasing skin moisture.
• Sericin has not been completely removed from raw silk threads, which will give a rougher texture to the fabric at the end.
• A special manufacturing process removes the outer irritant sericin coating of the silk, which makes it suitable as non-absorbable surgical sutures.
• Due to its elasticity and tensile strength, along with a natural affinity for keratin, sericin is primarily used in medicine for wound suturing.
• Sericin has a high hydroxy amino acid content which is important for the water-binding capacity which regulates the skin's moisture content.
• When used in cosmetics, sericin has been found to improve skin elasticity and several anti-aging factors, including an anti-wrinkle property.
• The cocoon, produced after the fourth moult, is covered with a continuous filament of the silk protein, fibroin, gummed together with sericin.
• When in the amorphous coil, sericin can also be easily be converted into a ?-sheet conformation, via repeated moisture absorption and mechanical stretching.
• Using gamma ray examination, it was determined that sericin fibers are composed typically of three layers, all with fibers running in different patterns of directionality.
