血红蛋白(HBG)是人体内含量最多的蛋白质之一,主要集中于血液的红细胞中。是第1个被纯化和确定有特殊生理功能的蛋白质。成熟红细胞中血红蛋白占红细胞内蛋白质总量的95%,是血液运输O2和CO2的重要载体物质,血液中每克血红蛋白可以携带1.34 ml氧气。正常成年男性含量为120~160g/L,成年女性含量为110~150g/L,70岁以上老年人相对降低,但是对于长期吸烟者而言血红蛋白明显增高。
Hemoglobin (HBG) is one of the most abundant proteins in the human body and is mainly concentrated in the blood’s red blood cells. Is the first protein purified and identified to have specific physiological functions. Hemoglobin in mature erythrocytes accounts for 95% of the total protein in erythrocytes, which is an important carrier substance for blood transport of O2 and CO2. Hemoglobin in the blood can carry 1.34 ml of oxygen. Normal adult men’s content of 120 ~ 160g / L, adult women’s content of 110 ~ 150g / L, 70-year-olds are relatively lower, but for long-term smokers, hemoglobin was significantly higher.
