海藻糖二十碳五烯酸酯的合成与表面性能(翻译)资料
海藻糖二十碳五烯酸酯的合成与表面性能摘要:海藻糖二十碳五烯酸酯是以二十碳五烯酸乙酯和海藻糖为底物,利用微生物脂肪酶在叔丁醇中通过脂基转换合成的。
反相高效液相色谱法加上二极管阵列检测和电喷雾质谱(RPHPLC-DAD-ESI-MS)分析表明,该反应混合物中存在单酯和二酯。
采用硅胶柱色谱法预处理反应混合物,然后再用高效液相色谱法洗脱海藻糖二十碳五烯酸酯,进一步纯化。
通过ESI-MS和核磁共振(NMR)对该化合物的结构进行表征。
证实,单酯为6-O-海藻糖二十碳五烯酸单酯。
接着,我们将海藻糖二十碳五烯酸酯的表面性能进行了研究。
结果显示表面张力,γcmc 和△G o mic随着温度的升高降低,但是每个分子占据的面积略有增加。
关键词:海藻糖二十碳五烯酸酯、酯基转移反应、分离纯化、结构鉴定、表面特性介绍膳食长链脂肪酸的二十碳五烯酸(EPA,20:5n- 3)属于n-3不饱和脂肪酸(多不饱和脂肪酸),其具有多种生物活性,并有生理功能[1,2]。
一些研究表明,它可用于预防和治疗心血管疾病[3-5]。
Stulnig[6]和Li[7]报道表明EPA可以从膜筏置换酰基化蛋白质,从而调节免疫应答。
EPA也可以在各种炎症的治疗临床应用作为辅助免疫抑制剂。
西田[8]提供的研究表明,EPA可能对H2O2氧化损伤起到内源性保护作用。
Mori [9]也显示EPA可降低体内氧化应激。
哈德曼[10]发现,EPA 可以增加抗癌药物的有效性。
巴布科克[11]报道,EPA补充剂可以促进保持体重和抑制肿瘤发展。
此外,一些文章也显示出n- 3脂肪酸可以对人类癌症治疗有帮助[12-14]。
EPA也作为预防医学治疗的推荐措施。
乙基二十碳五烯酸的酯已经被用于在动脉硬化性闭塞症,高血脂的治疗[15]。
然而,EPA是不稳定的,很容易在暴露于氧或活性氧中被氧化成脂质自由基或脂质过氧自由基。
虽然,在PUFA的主体相氧化已经研究充分,也有一些研究表明该多不饱和脂肪酸的在主体相的氧化稳定性从水性体系中[16,17]显著不同,Endo等人的报道称甘油三酯的氧化含有二十碳五烯酸和二十二碳六酸取决于氧化系统和甘油三酯结构。

masslynx加和分子量
masslynx加和分子量masslynx是一种常用的质谱数据处理软件,它可以用于分析质谱数据并计算化合物的加和分子量。
质谱是一种重要的分析技术,广泛应用于化学、生物、医药等领域。
本文将介绍masslynx的基本功能和应用,并探讨加和分子量在化学研究中的重要性。
我们来了解一下masslynx的基本功能。
masslynx是由Waters公司开发的一款质谱数据处理软件,主要用于质谱仪器的数据获取、处理和解析。
它支持多种质谱仪器的数据导入,包括液相色谱-质谱联用仪(LC-MS)、气相色谱-质谱联用仪(GC-MS)等。
masslynx可以将质谱仪器获取的原始数据进行处理和解析,提取出化合物的质谱图谱和质谱峰,从而进一步分析和确定化合物的结构和性质。
在masslynx中计算加和分子量是一项常见的功能。
加和分子量是指化合物中各个原子的相对原子质量之和,它是化合物的一个重要物理性质。
masslynx可以通过质谱数据计算出化合物的加和分子量,从而帮助化学家确定化合物的组成和结构。
在使用masslynx计算加和分子量时,首先需要导入质谱数据,然后通过质谱峰的质量-荷质比和相对强度来确定化合物的分子离子峰和碎片离子峰,最后根据这些质谱峰的质量和相对强度来计算加和分子量。
加和分子量在化学研究中具有重要的意义。
首先,加和分子量是确定化合物组成和结构的重要依据。
通过计算加和分子量,化学家可以了解化合物中各个原子的相对含量和排列方式,从而推断出化合物的结构和性质。
其次,加和分子量可以用于判断化合物的纯度和质量。
纯度高的化合物通常具有较大的加和分子量,而杂质和杂质的分解产物通常具有较小的加和分子量。
因此,通过准确计算加和分子量,可以判断化合物的纯度和质量。
最后,加和分子量可以用于化学反应的计量和质量控制。
在合成化学中,化合物的加和分子量可以用于计算反应物的用量和产物的收率,从而控制化学反应的质量和效果。
除了计算加和分子量,masslynx还具有其他重要的功能。
Masslynx操作说明简介
Masslynx操作说明简介开机步骤1. 分别打开质谱、液相色谱和计算机电源,此时质谱主机内置的CPU会通过网线与计算机主机建立通讯联系,这个时间大约需要1至2分钟。
2. 等液相色谱通过自检后,进入Idle状态,依照液相色谱操作程序,依次进行操作。
(具体根据液相色谱不同型号来执行,下面以2695为例)。
a. 打开脱气机 (Degasser On)。
b. 湿灌注(Wet Prime)。
c. Purge Injector。
d. 平衡色谱柱。
3. 双击桌面上的 MassLynx4.1图标进入质谱软件。
注:如果进入Masslynx软件时出现提示:“The embedded system is not responding, The system will run in standalone mode”,则说明质谱内置的CPU(EPC)与电脑主机的通讯联系还未建立,此时无法控制质谱,请稍等后再进入软件,如果打开软件仅为处理数据则没有关系(质谱主机电源未开时进入软件也会有同样提示)。
4. 检查机械泵的油的状态(每星期),如果发现浑浊、缺油等状况,或者已经累积运行超过3000小时,请及时更换机械泵油。
5. 点击质谱调谐图标(MS Tune)进入质谱调谐窗口。
6. 选择菜单“Options –Pump”,这时机械泵将开始工作,同时分子涡轮泵会开始抽真空。
几分钟后,质谱仪就会达到真空要求,质谱仪前面板右上角的状态灯“Vacuum”将变绿。
7. 点击真空状态图标,检查真空规的状态,以确认真空达到要求。
8. 确认氮气气源输出已经打开,气体输出压力为90 psi。
9. 设置源温度(Source Temp)到目标温度。
质谱调谐窗口各项参数设定电喷雾电离源(ESI)1. 在质谱调谐窗口选定要使用的离子模式。
2. 点击进入下面Source界面,设定Source界面里的各项参数。
Capillary(KV) 加在ESI源内毛细管上的高压,正离子模式一般是在2.5-3.75KV 之间优化,负离子模式一般是在2.0-3.0KV之间优化。
不同烘焙温度下核桃壳挥发性成分分析
不同烘焙温度下核桃壳挥发性成分分析吴恒;吴雨松;刘劲芸;徐世涛;张虹娟;阴耕云【摘要】用体积分数75%的乙醇为提取液,采用热回流的方式获得不同烘焙温度下的核桃壳提取物,利用气相色谱-质谱联用技术(GC-MS)分别对挥发性成分进行分析,并以面积归一化法测定各个成分的相对含量.经不同烘焙温度处理后核桃壳的挥发性成分及含量差异较大,其中许多是重要的香料物质.160℃烘焙后6种主要香料成分为愈创木酚、香兰素、香草酸、丁香醛、4-羟基-2-甲氧基肉桂醛和3,5-二甲氧基-4-羟基肉桂醛的相对含量分别为1.97%、3.03%、5.08%、9.11%、31.42%和25.64%,总和高达76.25%;而不烘焙时对应成分的相对含量分别为0.91%、1.66%、2.03%、0.62%、3.07%和1.59%,总和只占9.88%.经烘焙后核桃壳中的主要香料物质的相对含量明显升高,显示了烘焙后的核桃壳在食品添加剂领域具有一定的利用价值,因此可将核桃壳烘焙后用于生产高附加值的香精香料.【期刊名称】《食品与发酵工业》【年(卷),期】2014(040)009【总页数】5页(P157-161)【关键词】核桃壳;烘培;挥发性成分;气质联用【作者】吴恒;吴雨松;刘劲芸;徐世涛;张虹娟;阴耕云【作者单位】云南中烟新材料科技有限公司,云南昆明,650106;云南中烟新材料科技有限公司,云南昆明,650106;云南中烟新材料科技有限公司,云南昆明,650106;云南中烟新材料科技有限公司,云南昆明,650106;云南中烟新材料科技有限公司,云南昆明,650106;云南中烟新材料科技有限公司,云南昆明,650106【正文语种】中文核桃壳是核桃取仁后的副产物,数据显示,2008年中国核桃年总产量为8.3×105t,按取仁率55%计算,中国每年产生核桃壳高达3.735×105t。
核桃壳质地坚硬,在加工核桃仁的过程中作为废弃物弃掉或焚烧,不仅利用价值低还会造成资源浪费和环境污染[1-2]。
