Two 3β-carboxy-24-ethylcholestanes (24R and 24S) have been isolated as a mixture from a carbonated sediment and characterised by comparison of their mass spectrometric and 1H NMR spectroscopic data with those of synthetic standards; their origin is still unknown, since their carbon skeleton has not yet been reported in living organisms.
从碳酸盐沉积物中分离出两种3β-羧基-24-乙基胆甾烷(24 R和24 S)的混合物,并通过将其质谱数据和1 H NMR光谱数据与合成标准品进行比较来表征。它们的起源仍是未知的,因为尚未在活生物体中报道其碳骨架。
