Proline Unit Converter

Proline is a nonessential amino acid, meaning your body can produce it from other amino acids (mainly glutamate). It is one of the 20 standard amino acids used to build proteins.

Proline makes up about 10% of all amino acids in collagen, the most abundant protein in the body. This makes it essential for maintaining the structure and strength of connective tissues such as skin, bone, cartilage, tendons, and blood vessels.

A plasma proline test measures how much proline is circulating in your blood. It helps clinicians evaluate how your body produces, uses, and breaks down this amino acid.

Proline is synthesized primarily in the liver from glutamate. It is also obtained from dietary sources rich in collagen and protein, such as meat, bone broth, dairy, and eggs.
