Valine is a branched-chain amino acid essential for protein synthesis, muscle repair, and energy production. Elevated levels may reflect metabolic disorders or excessive intake, while deficiencies impair muscle function and recovery. It is vital for maintaining anabolic processes and metabolic balance.

Urea Cycle

The urea cycle is the primary pathway for removing excess nitrogen from the body, converting ammonia into urea for excretion.

Acetyl-ornithine is a derivative of ornithine, an amino acid involved in the urea cycle, which regulates nitrogen metabolism and ammonia detoxification. Abnormal levels may indicate disturbances in urea cycle function, potentially contributing to hyperammonemia or metabolic dysfunctions in the liver. It may also reflect broader disruptions in amino acid metabolism related to malnutrition or inborn errors of metabolism.
Arginine is a semi-essential amino acid crucial for nitric oxide production, immune function, and wound healing. Deficiencies are associated with impaired endothelial function, increased cardiovascular risk, and immune suppression, while excessive levels can exacerbate certain metabolic disorders. It is vital for maintaining vascular and metabolic health.
Asparagine is a non-essential amino acid involved in protein synthesis and amino acid metabolism. Dysregulated levels may indicate hepatic or metabolic dysfunction, and its role in energy balance and stress responses makes it critical in cellular health. Alterations in asparagine metabolism are also being explored in cancer biology.
Aspartic acid is a non-essential amino acid involved in the urea cycle, neurotransmission, and energy metabolism. Dysregulation can reflect liver dysfunction or altered energy pathways, with potential implications for fatigue and metabolic disorders. It supports ammonia detoxification and cellular energy production.

Citrulline is an amino acid involved in the urea cycle and nitric oxide production. Elevated levels may indicate intestinal dysfunction or metabolic disorders, while low levels are associated with impaired nitrogen balance and urea cycle defects. It is essential for detoxifying ammonia and supporting vascular health.
