8,11,14-Eicosatriynoic Acid, as an inhibitor of prostaglandin, leukotriene biosynthesis, and arachidonic acid induced platelet aggregation, blocks human 12-lipoxygenase (12-LO), cyclooxygenase (COX), and 5-lipoxygenase (5-LO) with IC50 values of 0.46 μM, 14 μM, and 25 μM, respectively. Also, it inhibits the actions of slow-reacting substance of anaphylaxis with an IC50 value of 10 μM [1,2].
Lipoxygenases are found widely in fungi, plants, and animals in high levels. 12-LO is involved in a number of significant disease states and may play a role in oxidative glutamate toxicity. COX enzymes play elaborate roles in human physiology and pathology, involving neuronal, immune, renal, cardiovascular, gastrointestinal, and reproductive systems. COX enzymes are blocked by aspirin and a wide variety of other non-steroidal anti-inflammatory drugs, which makes them important clinically [3]. 5-LO is involved in cancer pathobiology. It is expressed by a variety of cancer cells including colon, lung, breast, and prostate and promotes cancer cell growth and neo-angiogenesis.
In vitro: Up to now, in vitro study of 8,11,14-Eicosatriynoic Acid is still in the development stage.
In vivo: Up to now, in vivo study of 8,11,14-Eicosatriynoic Acid is still in the development stage.

20种蛋白质氨基酸都是α氨基酸。
其中除了甘氨酸外,其他氨基酸都具有旋光性,旋光性是由分子的空间构象引起的,你可以理解成像你的手掌一样,左右手的指头位置不同导致左右手的区别。根据旋光性分为L型(左型)和D型(右型)两种。
组成生命的氨基酸基本上都是L型。
在一些解热镇痛药注射剂中,为避免药物发黄变色,又加入了氨基酸抗氧化剂(除了亚硫酸氢钠外)。氨基酸抗氧化剂有哪些呢,常用的。查了一下,含S的抗氧化剂有甲硫氨酸(Met)和半胱氨酸(Cys),是这些吗?还是有其他常用的呢?
氨基酸的结构通式:氨基酸是指一类含有羧基并在与羧基相连的碳原子下连有氨基的有机化合物。
人体所需的氨基酸约有22种,分非必需氨基酸和必需氨基酸(须从食物中供给)。另有酸性、碱性、中性、杂环分类,是根据其化学性质分类的。
1、必需氨基酸(essential amino acid): 指人体(或其它脊椎动物)不能合成或合成速度远不适应机体的需要,必需由食物蛋白供给,这些氨基酸称为必需氨基酸。共有10种其作用分别是:
(一) 赖氨酸(Lysine ):促进大脑发育,是肝及胆的组成成分,能促进脂肪代谢,调节松果腺、乳腺、黄体及卵巢,防止细胞退化;
(二) 色氨酸(Tryptophane):促进胃液及胰液的产生;
(三) 苯丙氨酸(Phenylalanine):参与消除肾及膀胱功能的损耗;
(四) 蛋氨酸(又叫甲硫氨酸)(Methionine);参与组成血红蛋白、组织与血清,有促进脾脏、胰脏及淋巴的功能;
(五) 苏氨酸(Threonine):有转变某些氨基酸达到平衡的功能;
(六) 异亮氨酸(Isoleucine ):参与胸腺、脾脏及脑下腺的调节以及代谢;脑下腺属总司令部作用于甲状腺、性腺;
(七) 亮氨酸(Leucine ):作用平衡异亮氨酸;
(八) 缬氨酸(Viline):作用于黄体、乳腺及卵巢。
(九) 组氨酸(Hlstidine):作用于代谢的调节;
(十) 精氨酸(Argnine):促进伤口愈合,精子蛋白成分。
2、非必需氨基酸(nonessential amino acid):指人(或其它脊椎动物)自己能由简单的前体合成,不需要从食物中获得的氨基酸。例如甘氨酸、丙氨酸等氨基酸。
各位,有没有做过附件中的比对分析,用什么软件来完成的
只有9个氨基酸,分子量1KD左右,想免疫小鼠制备单抗,有没有前辈做过这方面的东西?想了一些方法,但价值不大,请前辈们指教,不甚感激。
