英文
cholane-
A super acylation catalyst, 4 - dimethylamino pyridine ( dmap ), was prepared and used to synthesize cholesteryl ester compounds. four kinds of cholesteryl ester compounds such as cholesteryl p - alkoxyl benzoate, cholesteryl dicarboxylate, cholesteryl lumequeic ester and coattail - like cholesteryl ester were synthesized by acylation method and super acylation catalyst method. chemical structures and liquid crystal behaviors of the synthesized samples have been characterized by using element analysis, ftir, dsc and polarized microscopy with a hot stage
本文合成了高效酰化催化劑4 -二甲基氨基吡啶（ 4 - dimethylaminopyridine ， dmap ） ，採用酰氯化法和高效酰化催化劑法分別合成了對烷氧基苯甲酸膽甾醇酯、對稱脂族二羧酸膽甾醇酯、烯酸膽甾醇酯及燕尾型膽甾醇酯四類膽甾醇酯衍生物，並進行了化學結構和液晶性能的表徵。For example, previously consumers with high levels of cholesterol might have considered simply eliminating foods high in cholesterol and saturated fats. now, with greater access to information and wider food choices, choosing foods with mainly monounsaturated and polyunsaturated fat content or foods fortified with plant stanols or sterols which actively lower blood cholesterol levels, are just two examples of how consumers can expand, rather than narrow the variety of foods making up their daily diet
比如，以前高膽固醇的消費者只能考慮從食物中剔除高膽固醇和高飽和脂肪酸的部分，現在有了更多的信息和更好的教育，他們可以選擇單不飽和脂肪酸和多不飽和脂肪酸含量較高的食品，或者選擇用植物甾烷醇或甾醇強化的食品，這些食品都能夠降低血膽固醇水平。
