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.

The human body contains albumin as the most abundant protein in blood plasma, highlighting its fundamental biological importance. An albumin ingredient is simply a processed, concentrated form of this globular protein, derived from sources like egg whites, milk, or plants, for use in a variety of commercial applications.

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.

According to the scientific community, the final folded structure of a polypeptide chain is generally the one in which the free energy is minimized, resulting in a single stable conformation. This folding process leads to what is known as a compact protein, a term with distinct meanings in molecular biology and the commercial nutrition industry.

According to the National Institutes of Health, proteins carry out the duties specified by the information encoded in genes. An excellent example of a type of protein is hemoglobin, a complex molecule in red blood cells that plays a vital role in transporting oxygen from the lungs to the rest of the body.

Accounting for about 50% of the proteins in human blood plasma, albumin is the most abundant protein in the bloodstream. But beyond its high concentration, have you ever wondered, what is albumin made up of and how does its composition dictate its many critical roles?
