Amino Acid Transport during Muscle Contraction and Its Relevance to Exercise

摘要: The functional significance of amino acid transport in skeletal muscle has been explored by the use a variety techniques including work isolated perfused organs, incubated organs and tissue culture cells. results suggest that although there is wide systems different characteristics with responses to ionic, hormonal nervous modulation, glutamine (transported system Nm) demonstrates some unusual properties not observed acids transported other systems. Glutamine at very high rates heart both glutamate transporter appear be adaptively regulated availability glutamine. appears involved regulation number important metabolic processes (e. g., glutathione reduced/oxidised ratio protein glycogen synthesis). Furthermore, interact for volume control many features attributable changes concentration modulated via alteration cytoskeletal status.
