Figure 2From: Unsaturated phosphatidylcholines lining on the surface of cartilage and its possible physiological rolesIn this figure, the three bars represent the mean osmotic pressure difference (ΔP) generated by three SAPL "membranes", two of which were made with synthetic USPC ie POPC and PLPC, and one with synthetic SPC ie DPPC. There was no significant difference of ΔP between PLPC and DPPC 'membranes' was found (p < 0.05) though a significant difference was noticed between POPC and DPPC 'membranes' (p > 0.05).Back to article page
