Homologous series of alkyl phosphonic acids and alkyl sulfonic acids, along with inorganic orthophosphate and sulfate, have been identified in water extracts of the Murchison meteorite after conversion to their t-butyl dimethylsilyl (tBDMS) derivatives. The methyl, ethyl, propyl, and butyl compounds have been observed in both series. Five of the eight possible alkyl phosphonic acids and seven of the eight possible alkyl sulfonic acids through C4 have been identified. Abundances decrease with increasing carbon number as observed of other homologous series indigenous to Murchison. Concentrations range downward from approximately 380 nmol/gram in alkyl sulfonic acid series, and from 9 nmol/gram in the alkyl phosphonic acid series. Inorganic phosphate is present at about 25 micromoles/gram.
在将默奇森陨石的水提取物转化为叔丁基二甲基硅烷基（tBDMS）衍生物后，已鉴定出烷基膦酸和烷基磺酸的同系物系列，以及无机正磷酸盐和硫酸盐。在这两个系列中均观察到了甲基、乙基、丙基和丁基化合物。已鉴定出八个可能的烷基膦酸中的五个以及八个可能的C4以下烷基磺酸中的七个。正如在默奇森陨石中观察到的其他同系物系列一样，丰度随着碳原子数的增加而降低。烷基磺酸系列的浓度范围从约380 nmol/克向下递减，烷基膦酸系列的浓度范围从9 nmol/克向下递减。无机磷酸盐的含量约为25微摩尔/克。
