According to the British Nutrition Foundation, most people already consume more than enough protein, but the source of this protein is a critical factor for optimal health. For this reason, understanding why it is important to choose a variety of proteins is fundamental for a well-rounded and balanced diet.

As the most abundant protein in mammals, making up 25% to 35% of total protein content, collagen provides crucial structural support for the body. However, the vast world of proteins extends far beyond this one type, answering the question: do all proteins have collagen with a resounding 'no'?

Over 20,000 different types of proteins are encoded by the human genome alone, each with a specific function. So, how are all proteins different from each other, allowing for such incredible versatility? The answer lies in their intricate molecular makeup and hierarchical structure, determined primarily by the unique sequence of amino acids coded by our DNA.

While textbooks often reference 20 standard, or proteinogenic, amino acids, the reality of protein composition is far more complex and diverse. Not all proteins contain all 20 of these standard amino acids, and some even incorporate rarer, non-standard types through special genetic mechanisms. This expanded set of possibilities is a cornerstone of biological complexity and protein function.

The human body contains over 100,000 different types of proteins, each with a unique purpose. The answer to how do proteins differ from each other in structure and function lies in the precise sequence of their amino acid building blocks, which governs every subsequent level of folding and interaction.

According to the USDA, most Americans can benefit from increasing the variety of protein sources in their diets. This practice is crucial because why should you vary your protein? It's the most reliable way to obtain a full spectrum of essential amino acids, vitamins, and minerals that support the body's numerous functions.

While there are only 20 common types of amino acids, the sheer variety of proteins in nature is nearly limitless. This incredible diversity leads to a common question: are all proteins built the same? The answer is a resounding no, and the reasons for this lie in the hierarchical organization of their structure, from simple linear chains to complex three-dimensional marvels.
