The human body relies on just 20 standard amino acids to build the proteins essential for life, though over 500 exist in nature. Categorizing these fundamental building blocks is key to understanding their roles in protein structure, cellular function, and human nutrition.

Most amino acids are soluble in water, a property that is crucial for all life on Earth. The question of whether amino acids will dissolve in water depends heavily on their specific chemical structure, particularly the variable 'R' group, as well as the pH of the surrounding environment. This fundamental characteristic of amino acids allows them to function as the building blocks of proteins within the aqueous environment of cells.
