Ancient dna from woolly mammoths revealed that their blood contained special cold-adapted hemoglobin , which researchers reproduced in bacteria this year .
The plastic product still needs to undergo biological testing , and the hemoglobin replacement polymer is not yet a total blood substitute , but it is a crucial first step .
Red blood cells are packed with hemoglobin , and each hemoglobin molecule requires four oxygen-binding iron atoms .
红细胞中充满了血红蛋白,而每个血红蛋白分子需要四个结合氧铁原子。
Some , like hemoglobin , deliver oxygen from the lungs to the far reaches of the body .
有些蛋白质像血红蛋白一样,可以把氧从肺部输送到身体各处。
When oxygen hits blood it binds itself to the hemoglobin causing the shape and appearance of blood to change .
当氧气接触到血液时会和血红蛋白结合,从而改变血液的质地和外观。
The rbc indices ( measures of size and hemoglobin concentration ) are calculated by automated cell counters calibrated for the species in question .
自动细胞计数仪计算出红细胞指数(衡量细胞大小和血红蛋白浓度)并针对物种进行校正。
The hemoglobin concentration of each rbc , measured in g / dl , is defined as the mean corpuscular hemoglobin concentration .
平均红细胞血红蛋白浓度,即每个红细胞的血红蛋白浓度,单位是g/dl。
Hemoglobin is an iron-rich protein that gives the red color to blood . It also carries the oxygen from the lungs to the rest of the body .
血红蛋白是一种富含铁的蛋白质,它使血液呈现红色,能够携带氧气从肺部运输到机体其他各个部位。
The problem is that many of the factors driving the hemoglobin switch also have other crucial roles in red blood cells and in other parts of the body ; knocking them out creates severe new problems .
