B)in their heavy chain structure

Question

Quizplus · Accepted Answer

The different classes of antibodies differ from each other in their heavy chain structure. IgM has a pentamer structure, while IgG, IgA, and IgD have a monomer structure, and IgE has a dimer structure. Each class of antibody also has a slightly different function and is produced by different types of cells. However, these differences are not as significant as their heavy chain structure. Antigenic determinants are recognized by the variable regions of the antibody, which are similar across all classes, and the number of carbohydrate subunits is also not a significant difference between the classes.
