<jats:title>Abstract</jats:title> <jats:sec> <jats:title>Background</jats:title> <jats:p>Type 2 diabetes mellitus (T2DM) is a global health problem. Early identification of those at risk is necessary to prevent its onset through lifestyle and pharmacologic interventions. T2DM is characterized by metabolic abnormalities, including protein metabolism. Evaluation of the amino acid profile might be beneficial for early assessment.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods</jats:title> <jats:p>Liquid chromatography-mass spectrometry was performed to separate and quantify plasma amino acids from two groups of Thai individuals, patients with T2DM (n=103) and healthy individuals (n=104). Multivariate analysis was applied to compare free amino acid levels between groups. Subgroup analyses of patients with T2DM were performed to assess the association between amino acid profiles and important T2DM clinical characteristics.</jats:p> </jats:sec> <jats:sec> <jats:title>Results</jats:title> <jats:p>The multivariate analysis showed that glutamic acid was significantly associated with T2DM (OR 1.113, 95% CI 1.006 to 1.231) and results from the subgroup analyses showed that this correlation was significant in all subgroups of patients (p&amp;lt;0.05).</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions</jats:title> <jats:p>This finding needs to be confirmed in larger groups of patients with T2DM to explore glutamic acid as a biomarker for early prevention in particular at-risk groups. An in-depth understanding of the involvement of glutamic acid in T2DM could enhance our understanding of the disease and potentially provide novel interventions.</jats:p> </jats:sec>
