Sericin is a protein created by Bombyx mori (silkworms) in the production of silk. [1] Silk is a fibre produced by the silkworm in production of its cocoon. It consists mainly of two proteins, fibroin and sericin. Silk consists of 70–80% fibroin and 20–30% sericin; fibroin being the structural center of the silk, and sericin being the gum ...
Silkworms are the larvae of silk moths. The silkworm is of particular economic value, being a primary producer of silk . The silkworm's preferred food are the leaves of white mulberry , though they may eat other species of mulberry, and even leaves of other plants like the Osage orange .
Silkworms produce silk when undergoing larval to adult metamorphosis. Raspy crickets produce silk to form nests. Honeybee and bumblebee larvae produce silk to strengthen the wax cells in which they pupate. [1] Bulldog ants spin cocoons to protect themselves during pupation. [1] Weaver ants use silk to connect leaves together to make communal ...
The production of silk originated in China in the Neolithic period, although it would eventually reach other places of the world (Yangshao culture, 4th millennium BC). Silk production remained confined to China until the Silk Road opened at some point during the latter part of the 1st millennium BC, though China maintained its virtual monopoly over silk production for another thousand years.
Fibroin is an insoluble protein present in silk produced by numerous insects, such as the larvae of Bombyx mori, and other moth genera such as Antheraea, Cricula, Samia and Gonometa. Silk in its raw state consists of two main proteins, sericin and fibroin, with a glue-like layer of sericin coating two singular filaments of fibroin called brins.
Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, the caterpillar of the domestic silkmoth is the most widely used and intensively studied silkworm. This species of silkmoth is no longer found in the wild as they have been modified through selective ...
Schistosomiasis is caused by parasitic worms, picked up in infested waters, which drill through people's skin and lay eggs in their bodies.
Silk was first produced sometime during the third millennium BCE by the Chinese. By the first century CE, there was a steady flow of silk into the Roman Empire. [ 1 ] With the rise of the Sassanid Empire and the subsequent Roman–Persian Wars , importing silk to Europe became increasingly difficult and expensive.
