膽甾醇 的英文怎麼說
中文拼音 [dǎnzāichún]
膽甾醇
英文
cholcsterol-
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。Their clients include several major food and pharmaceutical companies which have asked for vehicles for nutraceuticals such as lycopene ( which can lower the risk of contracting prostrate or breast cancer ), phytosterol ( which helps prevent the accumulation of cholesterol ), and lutein ( which retards cataract growth )
他們的客戶包括一些大型食品及制藥公司,要求製作的"納米車"包括能降低患收縮無力前列腺癌和乳腺癌的可能性的番茄紅素,有助於防止膽固醇積累的植物甾醇,以及能阻止白內障形成的葉黃素。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。Cholesteryl carboxylic ester
膽甾醇羧酸酯There are usually some disadvantages such as more toxicity and low yield in the acetylating reaction which was used to synthesize cholesteryl ester liquid crystals
合成膽甾醇酯常用的酰氯化法存在毒性大,產率低的缺陷。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。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。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。The results showed that when hogwash oil into edible oil upwards of 10 %, the characteristic peak of cholesterol could be observed obviously
利用極性毛細管色譜柱可將油脂中的膽固醇和植物甾醇很好地分離,從而可鑒別油樣中是否混有地溝油。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。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。Preparation and study of the blood compatibility of cholesteryl liquid crystal composite membranes
膽甾醇液晶復合膜的制備及血液相容性研究For ten samples synthesized, six ones exhibit cholesteryl liquid crystal behaviors and four ones are not
合成的10個膽甾醇酯樣品中, 6個具有液晶性, 4個不具有液晶性。The research results showed that the dmap is an effective catalyst to synthesize cholesteryl ester compounds. in the reactions, improving yield and purity, reducing toxicity as well as simplifying operation process can be carried out
研究結果表明,高效酰化催化劑法是十分有效的酰化方法,在合成膽甾醇酯液晶中可較大幅度地提高產品的產率與純度、簡化操作、降低反應毒性。分享友人
