中文拼音 [shēngzāichún]
生甾醇
英文
biostearin-
The main physiological function of phytosterol is its lowering cholesterol content effect, which is effective through two mechanisms, inhibiting the adorption of cholesterol and effecting the metabolism of cholesterol
植物甾醇的生理功能主要為降膽固醇效果，目前認為通過二種機制而起作用：抑制膽固醇的吸收和影響膽固醇代謝。This paper reviewed the progress of structure - activity relationship and chemosynthetic methods of brassinosteroids in recent years
摘要綜述了油菜甾醇內酯類植物生長調節劑的結構與活性關系及近年來的化學合成方法。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。They were then prescribed a diet that included more specific foods, such as raw almonds, tofu and other soy foods, viscous fibers such as oatmeal, barley, okra and eggplant, and plant sterol - enriched margarine
如生杏仁豆腐和其他一些豆製品粘性纖維食品，如燕麥大麥秋葵和茄子富含植物甾醇的人造黃油等。They were then prescribed a diet that included more specific foods, such as raw almonds, tofu and other soy foods, viscous fibers such as oatmeal, barley, okra and eggplant, and plant sterol - enriched margarine. after a year, the group who stuck faithfully to the new eating plan lowered their cholesterol by an average of 29 percent
詹金斯為他們制定的新飲食計劃中包括：一些特別的食物，如生杏仁豆腐和其他一些豆製品粘性纖維食品，如燕麥大麥秋葵和茄子富含植物甾醇的人造黃油等。Microbial transformation of soybean sterol
大豆甾醇側鏈的生物降解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
化學結構對液晶性的影響表現為：分子中引入苯環剛性結構可以提高液晶的相變溫度和穩定性；脂族二羧酸膽甾醇酯中脂肪鏈的長度增加會降低液晶的穩定性；而末端含有燕尾結構則對液晶態的形成產生不利影響。On the basis of anal zing structure - activity relationship, the key points and solving methods of synthesizing brassinosteroids are introduced from the synthesis of matrix - cycle and introducing side chain
在分析油菜甾醇內酯類植物生長調節劑結構與活性關系的基礎上，從母環的合成和側鏈的引入兩個方面詳細介紹了該類化合物的合成關鍵及解決方法。This enzyme is industrially important and useful for the clinical determination of total or free serum cholesterol by coupling with related enzymes, the determination of the steric configuration of 3 3 - hydroxysteroids and the preparation of hormone
膽固醇氧化酶是膽固醇代謝的關鍵酶之一，它催化膽固醇氧化及異構反應，生成膽甾- 4 -烯- 3 -酮和過氧化氫。分享友人
