Functions of fatty acid binding proteins

Summary Cytosolic fatty acid binding proteins (FABP) belong to a gene family of which eight members have been conclusively identified. These 14–15 kDa proteins are abundantly expressed in a highly tissue-specific manner. Although the functions of the cytosolic FABP are not clearly established, they appear to enhance the transfer of long-chain fatty acids between artificial and native lipid membranes, and also to have a stimulatory effect on a number of enzymes of fatty acid metabolism in vitro. These findings, as well as the tissue expression, ligand binding properties, ontogeny and regulation of these proteins provide a considerable body of indirect evidence supporting a broad role for the FABP in the intracellular transport and metabolism of long-chain fatty acids. The available data also support the existence of structure- and tissue-specific specialization of function among different members of the FABP gene family. Moreover, FABP may also have a possible role in the modulation of cell growth and proliferation, possibly by virtue of their affinity for ligands such as prostaglandins, leukotrienes and fatty acids, which are known to influence cell growth activity. FABP structurally unrelated to the cytosolic gene family have also been identified in the plasma membranes of several tissues (FABP_pm). These proteins have not been fully characterized to date, but strong evidence suggests that they function in the transport of long-chain fatty acids across the plasma membrane.     

以丙烯酸-β-羟乙酯与丙烯酸为原料制备二丙烯酸乙二醇酯

以丙烯酸（AA）与丙烯酸-β-羟基乙酯（HEA）为原料，经酯化反应合成出了二丙烯酸乙二醇酯（EGDA）。以EGDA得率为考核指标，对催化剂种类及用量、阻聚剂种类及用量等合成条件进行了实验研究与优化，发现对于该反应，环己烷是比苯更优的带水剂，反应宜采用减压降温的方法抑制聚合的发生。对比分析表明，采用该方法制备EGDA的得率比直接酯化法、酯交换法更高，且产品的品质更好。
