Fig. 3.

Concentrations of three neutral lipids on the basis of their fatty acids in germ cells and residual bodies. Pachytene spermatocytes (PtS), round spermatids (RS), and residual bodies (RB) (white, hatched, and black bars, respectively) are compared with each and with seminiferous tubules (ST, gray bars). The lipids were quantified by their fatty acids, and their concentrations are expressed on the basis of a fixed amount of lipid phosphorus (note the ten times larger scale for TAG concentration). “C₂₄ V” refers to the sum of 24:4n-6 + 24:5n-6; “C₂₆–C₃₂ V” refers to the sum of all very long chain tetraenoic and pentaenoic fatty acids having this chain length range. Values with different letters (a-d) are significantly different, P < 0.05. Abbreviations: ADG, triglyceride with an ether bond; CE, cholesterol ester; TAG, triacylglycerol; V, very long chain polyenes.
