What are the three types of proteins?

The correct classification of proteins into types often emphasizes their structural properties and functions. Globular, fibrous, and membrane proteins represent distinct categories based on their shape and roles in biological systems.

Globular proteins are typically spherical and water-soluble, which allows them to function well in metabolic processes, such as enzymes and antibodies. Fibrous proteins are elongated and rope-like, providing structural support and strength, commonly found in connective tissues, hair, and fibers like collagen and keratin. Membrane proteins are embedded in or associated with cellular membranes and play crucial roles in communication, transportation, and cellular structure.

This classification highlights the diverse functions that proteins perform in biological organisms, reflecting their varied structures.
