使用分子方法追踪生物地球化学途径提高了我们对沉积记录中碳循环和生命遗产的基本理解。为此，特定化合物的放射性碳分析有助于揭示复杂环境基质中一系列生物标志物的周转、年龄和来源。然而，尽管氨基酸对生命具有基础重要性，并且在整个地质空间和时间中无所不在，但氨基酸的生物地球化学循环在很大程度上仍未被探索。在这里，我们讨论使用氨基酸特异性放射性碳来加深我们对食物网和沉积有机碳的生物地球化学知识的潜力。
Tracing of biogeochemical pathways using molecular approaches has advanced our basic understanding of the carbon cycle and life's legacy in the sedimentary record. To this end, compound-specific radiocarbon analysis has been instrumental in shedding light on the turnover, age, and sources of a range of biomarkers embedded within complex environmental matrices. However, despite their foundational importance for life and their omnipresence throughout geologic space and time, the biogeochemical cycling of amino acids remains largely unexplored. Here, we discuss the potential of using amino acid-specific radiocarbon to deepen our knowledge of the biogeochemistry of food webs and sedimentary organic carbon.
