As the most abundant free amino acid circulating in human blood, L-Glutamine is often discussed in the fitness and health communities. Understanding what is L-Glutamine made of reveals its fundamental chemical structure and how the body naturally produces this critical nutrient, primarily from glutamate and ammonia.

In the world of amino acids, proline is an unusual protein building block because its side chain is covalently bonded to its own backbone, forming a distinctive cyclic structure. This unique arrangement is central to understanding what does proline contain and why it functions differently from other amino acids in protein structures. Proline is composed of carbon, hydrogen, nitrogen, and oxygen, arranged in a specific five-membered ring that imparts rigidity and influences protein folding.

A staggering 95% of the body's creatine is stored in skeletal muscles, but despite being derived from amino acids, creatine is not an amino itself. This article clarifies the fundamental distinction between creatine and amino acids, detailing how they function uniquely to support athletic performance.
