2. Oxygen–hemoglobin dissociation curve - Wikipedia

   en.wikipedia.org/wiki/Oxygen–hemoglobin...

   The T state has a lower affinity for oxygen than the R state, so with increased acidity, the hemoglobin binds less O 2 for a given P O2 (and more H +). This is known as the Bohr effect . [ 4 ] A reduction in the total binding capacity of hemoglobin to oxygen (i.e. shifting the curve down, not just to the right) due to reduced pH is called the ...

3. Hemoglobin - Wikipedia

   en.wikipedia.org/wiki/Hemoglobin

   The Bohr effect favors the T state rather than the R state. (shifts the O 2-saturation curve to the right). Conversely, when the carbon dioxide levels in the blood decrease (i.e., in the lung capillaries), carbon dioxide and protons are released from hemoglobin, increasing the oxygen affinity of the protein.

4. Bohr effect - Wikipedia

   en.wikipedia.org/wiki/Bohr_effect

   In the R state, the ionic pairings are absent, meaning that the R state's stability increases when the pH increases, as these residues are less likely to stay protonated in a more basic environment. The Bohr effect works by simultaneously destabilizing the high-affinity R state and stabilizing the low-affinity T state, which leads to an overall ...

5. Bleeders (film) - Wikipedia

   en.wikipedia.org/wiki/Bleeders_(film)

   Bleeders (also known as Hemoglobin) is a 1997 Canadian horror film directed by Peter Svatek and based upon H. P. Lovecraft's story "The Lurking Fear". It premiered at the Fantastisk Film Festival Lund in Sweden on September 14, 1997, and was released direct to video the following year. [ 1 ]

6. Near-infrared window in biological tissue - Wikipedia

   en.wikipedia.org/wiki/Near-infrared_window_in...

   The near-infrared (NIR) window (also known as optical window or therapeutic window) defines the range of wavelengths from 650 to 1350 nanometre (nm) where light has its maximum depth of penetration in tissue. [1] Within the NIR window, scattering is the most dominant light-tissue interaction, and therefore the propagating light becomes diffused ...

7. Monod–Wyman–Changeux model - Wikipedia

   en.wikipedia.org/wiki/Monod–Wyman–Changeux_model

   In the historical model, each allosteric unit, called a protomer (generally assumed to be a subunit), can exist in two different conformational states – designated 'R' (for relaxed) or 'T' (for tense) states. In any one molecule, all protomers must be in the same state. That is to say, all subunits must be in either the R or the T state.

8. Methemoglobin - Wikipedia

   en.wikipedia.org/wiki/Methemoglobin

   For example, a methemoglobin concentration of 1.5 g/dL may represent a percentage of 10% in an otherwise healthy patient with a baseline hemoglobin of 15 mg/dL, whereas the presence of the same concentration of 1.5 g/dL of methemoglobin in an anemic patient with a baseline hemoglobin of 8 g/dL would represent a percentage of 18.75%.

9. Heme B - Wikipedia

   en.wikipedia.org/wiki/Heme_B

   Heme B or haem B (also known as protoheme IX) is the most abundant heme. [1] Hemoglobin and myoglobin are examples of oxygen transport proteins that contain heme B. The peroxidase family of enzymes also contain heme B. The COX-1 and COX-2 enzymes (cyclooxygenase) of recent fame, also contain heme B at one of two active sites.
