DESCRIPTION
General description
Hemoglobin is present in the red-blood corpuscles (RBCs) of vertebrates. It is composed of a globular structure with four α-β sub-units.[1]
Application
Hemoglobin from bovine blood has been used as a supplement in tryptone yeast extract salts and glucose (TYESG) agar for performing extracellular proteolytic activity of Flavobacterium psychrophilum.[2] It has also been used as a standard in Raman spectrometry.[3]
The solubility of α-elastin has been applied to construction of elastin-mimetic biomaterials.
Biochem/physiol Actions
Oxygen transporter. The Fe2+/Fe3+ balance is a physiological indicator of blood oxygenation; deoxygenated hemoglobin accessorizes a feedback loop by reducing nitrite to NO, a vasodilator which enhances blood flow to oxygen-deprived tissues.
Packaging
1 piece contains 100 g hemoglobin powder
Caution
Since native hemoglobin is readily oxidized in air, these preparations may be predominantly methemoglobin. |
