Detailed explanation-1: -Some examples of fibrous proteins include: Keratin, Myosin, collagen etc. Then we have globular proteins when the polypeptide chains coil around to give a spherical shape, the formation of globular proteins takes place. Such proteins are soluble in water and some examples include: Haemoglobin, Albumin, Insulin etc.
Detailed explanation-2: -There are seven types of proteins: antibodies, contractile proteins, enzymes, hormonal proteins, structural proteins, storage proteins, and transport proteins.
Detailed explanation-3: -Insulin and Albumin are the common fibrous proteins.
Detailed explanation-4: -Insulin is a small globular protein containing two chains, A (21 residues) and B (30 residues) (Fig. 2.1A).
Detailed explanation-5: -keratin is a class of tough, fibrous proteins that are the main structural component of hair, nails, horns, feathers, and hooves. Keratins are rich in sulfur-containing amino acids, especially cysteine, thus it lacks globular proteins.
