Research progress of amino acid metabolism in chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease(COPD)is a complex and heterogeneous disease,and it often merges with multiple extrapulmonary manifestations,including malnutrition and amino acid metabolism disorders.Recently,amino acid metabolomics has been extensively studied in the pathogenesis,treatment and prognosis of COPD.Thus,deeply understanding the role of amino acid metabolism in COPD and exploring the application of amino acid supplements are instructive for the systemic management of COPD.Therefore,this review addressed the role of amino acid metabolism in COPD.
