Serine Unit Converter

Serine is a non-essential amino acid, meaning your body can produce it on its own. It is one of the building blocks used to make proteins.

A plasma amino acid test measures the concentration of serine circulating in your blood. Beyond protein synthesis, serine plays important roles in brain function, cell membrane formation, immune support, and one-carbon metabolism.

Serine is also a precursor for glycine, cysteine, sphingolipids, phospholipids, and the neurotransmitter D-serine, making it central to many metabolic processes.

Serine is synthesized primarily in the liver and kidneys from glycine, and in the brain from the glycolytic intermediate 3-phosphoglycerate via astrocytes. It is also obtained from dietary sources such as soybeans, nuts, eggs, lentils, meat, and fish.
