Abstrakt: Hemoglobin and red blood cells (erythrocytes) have been studied extensively from the perspective of life and biomedical sciences. However, no analysis of hemoglobin and red blood cells from the perspective of chemical thermodynamics has been reported in the literature. Such an analysis would provide an insight into their structure and turnover from the aspect of biothermodynamics and bioenergetics. In this paper, a biothermodynamic analysis was made of hemoglobin and red blood cells. Molecular formulas, empirical formulas, biosynthesis reactions, and thermodynamic properties of formation and biosynthesis were determined for the alpha chain, beta chain, heme B, hemoglobin and red blood cells. Empirical formulas and thermodynamic properties of hemoglobin were compared to those of other biological macromolecules, which include proteins and nucleic acids. Moreover, the energetic requirements of biosynthesis of hemoglobin and red blood cells were analyzed. Based on this, a discussion was made of the specific structure of red blood cells (i.e. no nuclei nor organelles) and its role as an evolutionary adaptation for more energetically efficient biosynthesis needed for the turnover of red blood cells.
