汉语拼音:diàn fěn
以葡萄糖为单 位构成的多糖,分子式(C6H12O5)n。经淀粉酶水解形成麦芽糖,用酸或酶水解形成葡萄糖等。遇碘 呈蓝色。是粮食作物的种子或块根的主要成分,米、面中淀粉含量达60%—80%。
A popcorn kernel consists of an impervious hard outer hull and a dense starch-and-protein interior surrounding a bit of water and oil.
玉米花仁包括一个不渗透的坚硬外面的船身和内部密集的淀粉和蛋白质围拢一点儿水和油。In the early 1850's Virchow was led by the appearance of the tissue deposits of amyloid to suggest that it had a polysaccharide composition.
在19世纪50年代早期,Virchow被淀粉样蛋白的组织沉积表现所启发提出了淀粉样蛋白具有多糖的成分。Amyloid beta itself might be injuring nerve cells or the plaques, made of accumulations of amyloid beta, could be the culprits.
淀粉样β蛋白本身可能损伤神经细胞或者有它聚集形成的老年斑才是罪魁祸首。Lead researcher Jennifer Emond said: 'The results show that it's not just overall carbohydrates, but particularly starch.
首席研究员詹妮弗·艾蒙德说:“这个结果显示,总的来说,并不仅是碳水化合物,而特别是淀粉增加癌症复发的风险。”The amyloplast envelope began to degrade and released starch granules into cell matrix when amyloplast was full of starch granules.
当淀粉体被淀粉粒所充满,淀粉体被膜降解消失,释放淀粉粒到细胞基质中。GLYCOGEN a polysaccharide composed of many GLUCOSE units, with a branching structure similar to that of amylopectiN.
是一种由多个葡萄糖单位组成的多糖,与支链淀粉有着相似的分支结构。Difficulties with shunts and fistulae for vascular access do not in general seem to be more frequent in patients with amyloid.
建立血透路径的分流和瘘管的困难通常似乎在淀粉样变性病患者中不会增多。The results showed that the soluble starch was easy to mix with pure pollen among the different solid medium.
结果表明:在不同的固体介质中,可溶性淀粉易与纯花粉混合。For many workers, breakfast the next day is a little rice left over from dinner, fried with a bit of garlic salt.
很多工人就是从晚饭中省出一点米饭来加点大蒜盐(大蒜粉、盐和淀粉的混合物)做第二天的早饭。淀粉是葡萄糖的高聚体,在餐饮业又称芡粉,通式是(C6H10O5)n,水解到二糖阶段为麦芽糖,化学式是C12H22O11,完全水解后得到单糖(葡萄糖),化学式是C6H12O6 。淀粉有直链淀粉和支链淀粉两类。前者为无分支的螺旋结构;后者以24~30个葡萄糖残基以α-1,4-糖苷键首尾相连而成,在支链处为α-1,6-糖苷键。直链淀粉遇碘呈蓝色,支链淀粉遇碘呈紫红色。这并非是淀粉与碘发生了化学反应(reaction),产生相互作用(interaction),而是淀粉螺旋中央空穴恰能容下碘分子,通过范德华力,两者形成一种蓝黑色错合物。实验证明,单独的碘分子不能使淀粉变蓝,实际上使淀粉变蓝的是碘分子离子(I3)。淀粉是植物体中贮存的养分,贮存在种子和块茎中,各类植物中的淀粉含量都较高。
