4.2: Biological Oxygen Carriers - Chemistry LibreTexts
4.2: Biological Oxygen Carriers. As noted earlier, three solutions to the problem of dioxygen transport have evolved: hemoglobin (Hb), hemocyanin (Hc), and hemerythrin (Hr). Their remarkable distribution over plant and animal kingdoms is shown in Figure 4.8. 15.

Role of the Protein in Effecting Biological Oxygen Transport. Provision of Ligands to the Metal; Protection of the Metal-dioxygen Moiety; Modulation of Ligand-binding Properties
4.1: Biological Dioxygen Transport Systems - Chemistry LibreTexts
To model such systems, chemists have prepared several synthetic oxygen carriers, especially of iron and cobalt porphyrins. In this chapter the structures and properties of biological and nonbiological oxygen carriers are described, with particular attention to the hemoglobin family.
Oxygen Transport - Regulation of Tissue Oxygenation - NCBI Bookshelf
Oxygen is carried in the blood in two forms: (1) dissolved in plasma and RBC water (about 2% of the total) and (2) reversibly bound to hemoglobin (about 98% of the total). At physiological PO2 (40 < PO2 < 100 mm Hg), only a small amount of oxygen is dissolved in plasma since oxygen has such a low solubility.
Controlled oxygen delivery to power tissue regeneration
2024年5月22日 · In this review, we explore the biological relevance of oxygen at both a cellular and tissue level, and the importance of its controlled delivery via engineered biomaterials and devices.
Synthetic oxygen carriers of biological interest

Kinetics of Formation of Biological Oxygen Carriers
Abstract. At this point in time, there are only three known types of resyijratory proteins involving only two transition elements (Chart I). 1–4 These function to transport and store oxygen and therefore play a key role in biochemical processes. They can increase by up to one hundred fold the amount of oxygen delivered to tissues.
Perfluorocarbon-based oxygen carriers: from physics to …
2020年11月3日 · Developing biocompatible, synthetic oxygen carriers is a consistently challenging task that researchers have been pursuing for decades. Perfluorocarbons (PFC) are fascinating compounds with a huge capacity to dissolve gases, where the respiratory gases are of special interest for current investigations.
