What does ASBT stand for?

Explanation:
ASBT stands for Apical Sodium-dependent Bile Acid Transporter. This transporter sits on the apical (luminal) surface of ileal enterocytes and uses the sodium gradient to move bile acids from the intestinal lumen into the cells, a crucial step in the enterohepatic circulation that recycles bile acids back to the liver. The name directly reflects its location (apical), its energy source (sodium-dependent), and its role (bile acid transporter). The other descriptions don’t match the established term—for example, there’s no such thing as an anterior, activated secondary, or anionic solute bile transporter in this context.
