The appearance of d‐amino acids in mammals and humans has important implications in the life sciences. d/l‐Amino acid mixtures play a key role in human physiology and pathology; thus, the introduction of artificial receptors for the real‐time quantification of both the concentration and d/l composition of amino acids is very promising for the study of biological processes and for the diagnosis and
外观d -氨基酸在哺乳动物和人类在生命科学领域具有重要意义。d / l-氨基酸混合物在人体生理和病理中起着关键作用;因此,引入人工受体来实时定量浓度和d / l氨基酸的组成对于生物学过程的研究以及疾病的诊断和治疗是非常有前途的。现在,我们报告了一种与水溶液兼容的传感检测方法,可以快速确定微摩尔浓度下的绝对构型,对映体组成和半胱氨酸的总量。该方法依赖于快速的UV和CD测量,可提供涵盖宽浓度范围和模拟体液中d / l-半胱氨酸比率截然不同的样品的准确立体化学信息。竞争实验表明,其他氨基酸和生物硫醇不会干扰半胱氨酸靶向的传感。
