The Sodium-Dependent Neutral Amino Acid Transporter (SNAT) is a protein that helps transport neutral amino acids across cell membranes. It relies on sodium ions (Na+) to facilitate this process, meaning that the transport of amino acids is coupled with the movement of sodium. This mechanism is essential for maintaining amino acid levels in cells, which are crucial for various biological functions. SNAT plays a significant role in nutrient absorption in the intestines and the reabsorption of amino acids in the kidneys. By efficiently transporting amino acids, SNAT contributes to protein synthesis and overall metabolic health. Dysfunction in this transporter can lead to various health issues, including metabolic disorders.
