Fig. 1: Overview of plasma membrane amino acid transporters.
From: Quantitative modelling of amino acid transport and homeostasis in mammalian cells

Symporters are shown in green, antiporters in blue, and uniporters in red. Common names and solute carrier number are listed for each transporter. The substrate specificity of each transporters is indicated by color code (green = neutral, red = anionic, and blue = cationic). Specific amino acids are labeled as indicated.
