  人钠二羧酸协同转运蛋白3(humanna~+dicarboxylatecotransporter3，hnadc3)基因的编码产物是位于多种上皮细胞膜表面的一类介导琥珀酸、枸橼酸及-酮戊二酸等三羧酸循环中间产物转运的蛋白。
• Phenyl group introducing to cholesteryl ester molecules can enhance the phase transition temperatures of the liquid crystals and their stability . an increase in the chain length for cholesteryl dicarboxylate samples reduced stability of liquid crystal phases . while coattail-like structures on the ester group of the molecules have an adverse effect to form cholesteryl liquid crystal phase
  化学结构对液晶性的影响表现为：分子中引入苯环刚性结构可以提高液晶的相变温度和稳定性；脂族二羧酸胆甾醇酯中脂肪链的长度增加会降低液晶的稳定性；而末端含有燕尾结构则对液晶态的形成产生不利影响。
