中文拼音 [dǎnzāichúnjī]
膽甾醇基
英文
cholesteryl-
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。Here we show that 27 - hydroxycholesterol ( 27hc ), an abundant cholesterol metabolite that is elevated with hypercholesterolemia and found in atherosclerotic lesions, is a competitive antagonist of estrogen receptor action in the vasculature
在此我們發現27 -羥基膽甾醇（ 27hc ）是一種含量豐富的膽固醇代謝產物，它的過量引起高膽固醇血癥並存於粥樣硬化病變中，在血管中是雌激素受體競爭性拮抗劑。But there ' s another compound in the blood ? 27 - hydroxycholesterol, or 27hc ? that can also attach to the same receptors but doesn ' t trigger the protective benefits for the heart, according to a study of mice published yesterday in nature medicine
昨天在自然醫學雜志上發表的對鼠的一項研究表明血液中存在另一種化合物- 27 -羥基膽甾醇，或27hc -它同樣能夠和相同的受體結合而不觸發對心臟的保護作用。
