Although haemoglobin is a known carrier of oxygen in erythrocytes that functions to transport oxygen over a long range, its physiological roles outside erythrocytes are largely elusive1,2. Here we found that chondrocytes produced massive amounts of haemoglobin to form eosin-positive bodies in their ...

THE transformation of oxyhaemoglobin (HbO 2 ) to methaemoglobin (Hb + ) involves an electron transfer whereby the ferrous haem iron is oxidized, with the simultaneous reduction of the oxidant, oxygen. In the event of the O 2 being fully reduced (to H 2 O) in the process 1 , 1 mole ...
These results indicate that changes in the relative contents of leghaemoglobin during nodule development contribute to more effective nitrogen fixation which is mediated by changes in the capacities of oxygen transport. 展开 关键词: Leghaemoglobin heterogeneity O2-binding affinity Pea (root) Rhizobium ...
the gaseous phytohormone ethylene is rapidly accumulated in the plant submerged tissues, assuming an important regulatory factor in plant-waterlogging tolerance. In this review, we summarize recent advances in research on the mechanisms of ethylene in the regulation of plant responses to waterlogging stre...
RBCs contain haemoglobin molecules (Hb) which play the main role to transport oxygen and carbon dioxide among the lungs and tissues (Kuhn et al., 2017; Koleva et al., 2020). It's well known that using the radiotherapy with high doses to control the tumours has side effects on blood ...
The role of the distal histidine in myoglobin and haemoglobin The distal E7 histidine in vertebrate myoglobins and haemoglobins has been strongly conserved during evolution and is thought to be important in fine-tuning the ligand affinities of these proteins. A hydrogen bond between the N epsilon ...
Describe the function of iron in the body. What happens if there is an excess or a deficit of it? What is the function of haemoglobin? What is the function of hemoglobin in a body? Explain how anemia affect the electron transport chain. ...
The Separate Effects of H+ and 2,3‐DPG on the Oxygen Equilibrium Curve of Human Blood S ummary . Addition of non-saturating amounts of 2,3-DPG (2,3-diphosphoglycerate) within the red cell (2,3-DPG/haemoglobin less than I) intially reduces Hill's parameter, n. With increasing 2,...
