Plasma levels of amino acids in common marmosets and human.

Plasma of common marmosets including female and male marmosets (n = 50) was analyzed for amino acids by LCMS to compare with values of human plasma (H). Concentration of phenylalanine (A) and methionine (B), histidine (C) of common marmoset (CM, mean ± SD) were significantly higher than human. Arginine (D) and leucine/isoleucine (E) were significantly lower in CM than H. Lysine (F) and tyrosine (G) values of CM were not significantly different from H (Mean ± SD). * p < 0.05.

本研究采用液相色谱-质谱联用（LCMS）技术，对50只雌雄普通狨猴（common marmoset，CM）的血浆样本进行氨基酸含量分析，并与人类血浆（H）的对应检测值进行对比。结果表明，普通狨猴血浆中苯丙氨酸（A）、蛋氨酸（B）及组氨酸（C）的浓度（均值±标准差）均显著高于人类血浆；精氨酸（D）与亮氨酸/异亮氨酸（E）的浓度则显著低于人类血浆；而赖氨酸（F）与酪氨酸（G）的浓度与人类血浆无显著统计学差异（均值±标准差）。* p < 0.05。
