                                According to scientific studies, proline constitutes approximately 10% to 17% of the total amino acid composition in collagen, a crucial structural protein in the body. However, when considering its post-translationally modified form, hydroxyproline, this figure increases significantly, making it one of the most abundant amino acids in the protein. This high concentration is essential for giving collagen its signature triple helix shape and immense strength.
