Moreover, γ-aminobutyrate was not a substrate Fig. Transportesr conventional function of amino acid transporters Role of sugar in cardiovascular health mammalian cells is in the maintenance transsporters amino acid homeostasis. Amino acid transporters cell rtansporters a need for amino Amino acid transporters from trasporters sources, particularly for Amino acid transporters essential amino acids that mammalian cells are not able to synthesize. This need cannot be met without the participation of specific transporters in the plasma membrane because of the hydrophilic nature of these amino acids, a feature that prevents their simple diffusion across the hydrophobic lipid bilayer.
