Over 10,000 different types of proteins are found in the human body, from our organs and muscles to our skin and hair. These complex molecules, constructed from amino acids, perform an array of vital functions that assist our body in growth, maintenance, and defense.

Protein is a crucial macronutrient present in every single cell of the human body, forming about 20% of total body weight. Though often associated with muscle building, its responsibilities are far more extensive, as countless different proteins perform a wide array of specialized jobs. So, what are the three roles of proteins that are fundamental to life itself?

By definition, a lipoprotein is a biochemical assembly whose primary function is to transport hydrophobic lipid molecules, such as fats and cholesterol, through the aqueous environment of the bloodstream. These particles are essential for delivering lipids to cells throughout the body for energy, cell building, and hormone production. Without lipoproteins, the body's fat-based molecules would be unable to travel safely and efficiently through the water-based blood plasma.

Proteins are complex macromolecules found in every living cell, responsible for driving nearly all biological processes. This guide explains which are the functions of proteins 4 points, detailing their critical roles as catalysts, structural components, messengers, and transporters in the human body.

According to the National Kidney Foundation, the recommended dietary allowance (RDA) for protein is 0.8 grams per kilogram of body weight. Understanding what are the three roles of proteins in the body is fundamental to grasping why this macronutrient is so vital for maintaining life, from building tissues to catalyzing metabolic reactions and transporting essential molecules throughout the body.

As the most abundant protein in human blood plasma, comprising about 50–60% of total plasma protein, albumin is indispensable for health. Understanding **what is the main function of albumin?** reveals its critical role in maintaining bodily homeostasis through diet and nutrition.
