Detailed explanation-1: -An example of tertiary structure is a single-domain globular protein. Globular proteins (6) are sphere-like proteins that are more or less soluble in aqueous solutions (the other two protein classes are membrane and fibrous proteins) (Figure 13).
Detailed explanation-2: -Globular proteins are categorized into four structural classes: all-, all-, +, and / (Levitt and Chothia, 1976).
Detailed explanation-3: -Among the most known globular proteins is hemoglobin, a member of the globin protein family. Other globular proteins are the alpha, beta and gamma (IgA, IgD, IgE, IgG and IgM) globulin.
Detailed explanation-4: -Some globular proteins have a quaternary structure, and it is formed when two or more globular protein molecules (monomer) join together and form a multimeric unit. Hemoglobin is a good example of a protein that has a quarternary structure.
