7.5.2 Outline the difference between fibrous and globular proteins, with reference to two examples of each protein type. Protein shape can be categorised as either fibrous or globular. Fibrous proteins tend to be elongated, physically tough and insoluble in water. Collagen found in the skin and ...
Proteins such as enzymes, channels, signaling molecules and adaptors carry out important functions in living organisms. Fibrous and globular proteins comprise two large groups. Long stretches of coiled coil 伪-helices in fibers and fibrils, triple helices of collagen, and globular heme binding ...
Protein - Denaturation, Structure, Function: When a solution of a protein is boiled, the protein frequently becomes insoluble—i.e., it is denatured—and remains insoluble even when the solution is cooled. The denaturation of the proteins of egg white by
observed by kinetic circular dichroism measurements at 220–225 nm for 14 different proteins are summarized, and the ellipticity values are compared with those for the final native proteins and also with the ellipticities expected from a physical theory of protein and polypeptide secondary structure. ...
Protein - Keratin, Structure, Function: Keratin, the structural protein of epithelial cells in the outermost layers of the skin, has been isolated from hair, nails, hoofs, and feathers. Keratin is completely insoluble in cold or hot water; it is not atta

Langya Henipavirus (LayV) infection is an emerging zoonotic disease that has been causing respiratory symptoms in China since 2019. For virus entry, LayV’s genome encodes the fusion protein F and the attachment glycoprotein G. However, the structural an
Protein - Isolation, Determination, Structure: Animal material usually contains large amounts of protein and lipids and small amounts of carbohydrate; in plants, the bulk of the dry matter is usually carbohydrate. If it is necessary to determine the amou
