Application of Additional CuO Reaction Products as Geochemical Indicators

这项工作将完成Miguel Goni关于环境样品中木质素表征的CuO方法得到的75-100个反应产物(除简单酚之外)的地球化学应用的论文研究。到目前为止，P.I.S已经在土壤和沉积物中发现了CuO反应产物混合物，其中包括来自特定氨基酸、脂肪、海带和木质素的化合物，以及一系列由木质素衍生的酚醛二聚体。现在提交了三篇描述角质蛋白工作的论文，一份关于氨基酸反应产物的地球化学性质的手稿正在准备中。P.I.S建议通过研究CuO反应产物组来结束这一项目：(A)似乎是海带独有的化合物和(B)可能携带新的地球化学信息的木质素二聚体。

The work proposed will complete the dissertation research of Miguel Goni on geochemical applications of the 75-100 reaction products (in addition to simple phenols) that are obtained from the CuO method sued to characterize lignins in environmental samples. To date, the P.I.'s have found CuO reaction product mixtures from soils and sediments to include compounds derived from specific amino acids, lipids, cutins, and kelps, along with an extensive suite of lignin-derived phenolic dimers. Three papers describing the cutin work are now submitted and a manuscript on the geochemistries of the amino acid reaction products is in preparation. The P.I.'s propose to wrap up this project by investigating the suites of CuO reaction products: (a) compounds that appear to be unique to kelps and (b) the lignin dimers, which potentially carry novel geochemical information.
