The amide-linked fatty acids of the sphingolipids of Acholeplasma axanthum S743 are predominantly hydroxy acids. These acids were shown by gas-liquid chromatography, mass spectrometry, and polarimetry to be the d(-)3-hydroxy fatty acids. The predominant component of the mixture was 3-hydroxyhexadecanoate (beta-hydroxypalmitate, hydroxy [h] 16:0) followed by h 20Delta (Delta = unsaturated), h14:0, h12:0, and h18Delta in decreasing order of concentration. The fatty acid profile indicates that these beta-hydroxy acids possibly arise from elongation of the fatty acids supplied in the growth medium.
无胆甾原体S743鞘脂类的酰胺连接脂肪酸主要是羟基酸。通过气液色谱法、质谱分析法和旋光测定法表明，这些酸是d(-)3-羟基脂肪酸。混合物的主要成分是3-羟基十六烷酸（β-羟基棕榈酸，羟基[h]16:0），其次是h 20Δ（Δ=不饱和）、h14:0、h12:0和h18Δ，浓度依次降低。脂肪酸谱表明，这些β-羟基酸可能来自生长培养基中提供的脂肪酸的延长。
