Proteins are one of the most abundant and diverse organic molecules in all living systems, performing a vast array of functions. To truly understand what category does a protein come under, one must look beyond a single label, as these vital molecules are classified in multiple ways depending on their structure, function, and composition.

The human body is composed of thousands of different proteins, all assembled from the same 20 amino acids but folded into unique three-dimensional shapes to perform a vast array of biological tasks. These essential macromolecules are broadly categorized into three main classes based on their structure, function, and solubility.

Over 50% of the dry weight of a typical cell is composed of proteins, highlighting their immense importance to life. So, what does protein look like on a molecular scale? The answer is far from simple, as its appearance changes dramatically depending on its structural complexity.

Proteins are fundamental macromolecules involved in nearly every cellular process, from structural support to cellular signaling. To understand their diverse functions, it's essential to know what are two types of proteins distinguished primarily by their molecular shape and solubility: fibrous and globular proteins.
