Referring to following statements, I would like to know on what range of wavelength is strongly absorbed by hemoglobin as shown below:
Does anyone have any suggestions?
Thanks in advance for any suggestions
In medical physics, the optical window is the portion of the visible and infrared spectrum where living tissue absorbs relatively little light. This window runs approximately from 650 nm to 1200 nm.
At shorter wavelengths, light is strongly absorbed by hemoglobin in blood, while at longer wavelengths water strongly absorbs infrared light.
https://en.wikipedia.org/wiki/Optical_windowReferring to following image, I would like to know on what high molar extinction corfficient is represented on hemolglobin function as shown below, on the other words, when molar extinction corfficient is high, what happen to hemoglobin in term of their functions?
Does anyone have any suggestions?
Thanks in advance for any suggestions
"Blood consists of two different types of hemoglobin: oxyhemoglobin ( H b O 2 {displaystyle HbO_{2}} HbO_{2}) is bound to oxygen, while deoxyhemoglobin ( H b {displaystyle Hb} Hb) is unbound to oxygen. These two different types of hemoglobin exhibit different absorption spectra that are normally represented in terms of molar extinction coefficients, as shown in Figure 1. The molar extinction coefficient of Hb has its highest absorption peak at 420 nm and a second peak at 580 nm. Its spectrum then gradually decreases as light wavelength increases. On the other hand, H b O 2 {displaystyle HbO2} HbO2 shows its highest absorption peak at 410 nm, and two secondary peaks at 550 nm and 600 nm. As light wavelengths passes 600 nm, H b O 2 {displaystyle HbO_{2}} HbO_{2} absorption decays much faster than Hb absorption. The points where the molar extinction coefficient spectra of H b {displaystyle Hb} Hb and H b O 2 {displaystyle HbO_{2}} HbO_{2} intersect are called isosbestic points."
Do Fish's hemoglobin work the same as human's hemoglobin?
Does anyone have any suggestions?
Thanks in advance for any suggestions
Any difference on hemoglobins between Fish and human?
