DPPC (color elements) interacts with water molecules (transparent part) in the image. This phospholipid is found in a solid/gel phase at 37 C (at the effective temperature of the human body). Its melting point is around 41.3 C. Therefore, when the temperature is above 41 C, DPPC is no longer found in a gel phase but in a liquid one. Department of Health and Human Services. Diphenyl phosphoryl chloride. Molecular Weight: 790.15. The data reveals an influence of HA on both the macro and micro structure of the DPPC Langmuir layer, and that the strength of this effect increases with decreasing molecular weight of HA and in presence of calcium ions.
