2,3 DPG, how is it produced in RBC and how does it interact with Hb; what is its relevance in altitude exposure, anemia and stored blood
糖酵解中间产物中以2,3-dpg的含量最多(动静脉血中:2,3-dpg的含量是3-磷酸甘油酸的177倍和239倍)。这是因为红细胞中存在二磷酸甘油酸(dpg)变位酶和2,3-dpg磷酸酶。这两种酶催化的反应是不可逆的。2,3-dpg生产支路如图《球棍模型》。

Ett organiskt fosfat med starka anionegenskaper som förekommer i humana röda blodkroppar i ungefär samma molarförhållande som hemoglobin. The ease with which haemoglobin releases oxygen to the tissues is controlled by erythrocytic 2,3-diphosphoglycerate (2,3-DPG) such that an increase in the concentration of 2,3-DPG decreases oxygen affinity and vice versa. This review article describes the synthesis and breakdown of 2,3-DPG in the Em … 2,3-DPG levels in the erythrocytes help regulate hemoglobin oxygenation (Figure 26.6).Unloading of oxygen at the P O 2 in tissue capillaries is increased by 2,3-DPG, and small changes in its concentration can have significant effects on oxygen release. 2,3-Diphosphoglycerate (2,3-DPG) is a special intermediate of glycolysis in erythrocytes which is rapidly consumed under conditions of normal oxygen tension. However, when hypoxia is encountered in peripheral tissues, the concentration of 2,3-DPG can accumulate to significant levels within hours.

Neonatal weight, 2,3-DPG concentration, Hct and Hb for all groups are shown in Figure 1.Erythrocyte 2,3-DPG concentration and neonatal weight increased in all groups by d 16 compared to d 9. The 2,3-DPG concentration at d 9 did not differ among the groups while at d 16 it was significantly lower in the NS group than in the C- and S groups (P
Hemoglobin is reponsible for carrying oxygen but that oxygen is no good if the transporter doesn't let go. Biochemically, we have molecules like CO2 and 2,3-
The results showed no significant relationship between smoking habits of mothers and their levels of hemoglobin, P50, and 2,3-DPG; only the hematocrit was slightly increased in smoking mothers. However, in fetal blood a significant correlation was found between the number of cigarettes smoked per day and levels of hemoglobin, hematocrit, and P50.
