“All animals with vertebrates have hemoglobin that makes the blood red. Blood without hemoglobin does not have color, ”the school books say. Why should hemoglobin be in our blood? What other colors shouldn’t there be? This is a very interesting question.
There is a fish called Ice-Fish that lives in the coldest waters of the South Pole Antarctica. These are much more delicate than ordinary fish; The bones are transparent. The blood of these fish, like a glass doll, is completely white. This ice-fish is the only living creature with no red blood in its spine. There are no red cells or hemoglobin in their blood. This unique fish draws oxygen from its large gills and slick skin.
How is it possible to live without hemoglobin? At what stage of hemoglobin biosynthesis does organisms join? Such questions were raised in ice-fish scientists! Scientists have got some exciting answers.
Scientists first noticed the genetic structure of ice-fish. No significant differences were observed when comparing ice-fish with the genetic structure of other fish with red blood. However, some enzymes were high in icefish, which could carry oxygen to cells and prevent the risk of free-oxygen. That is, hemoglobin-producing genes were inactive in ice-fish. Scientists thought this might be the case with other species. Hemoglobin-producing genes were also found in several primary organisms that lacked spinal cord and red blood cells. Some organisms, such as crab, have a substance called hemocyanin, which turns blue into the blood instead of hemoglobin. Such organisms also had genes that could produce hemoglobin! It is the scientists’ curiosity as to which genes should produce the unwanted substances.
Scientists who set out in search of answers have reached the beginning stages of biogas. Monocytes, such as amoebae, also have several chemical processes using oxygen. Microorganisms have added a unique chemical called par-fyrene to retain oxygen. When a mineral such as iron or copper is incorporated into the par-fyrene ring, the oxygen retention power increases. Such a mineral-par-ferrin compound increased oxygen consumption in monolayers. This mineral-par-fyrene compound must have played a large role in the formation of multicellular organisms over time. But the work of the par-fairens was somehow unstable, releasing free oxygen and placing it in the cell. As such, the protein wall grew around the par- fairin. Hemoglobin is one such compound. There is a wall of protein called globin, surrounded by an iron-par-fibrin called heme. Hemoglobin molecules combine with one another to further support the oxygen supply. Nature should have thought that this was a useful compound from the beginning of biogas. Scientists estimate that hemoglobin-producing genes should be preserved in all kinds of organisms without destroying nature.
As the evolution of multicellular organisms, several layers of cells grew. The direct contact of the atmosphere to the lining cells was then lost. The hemoglobin came to the aid of such a case. The oxygen-filled hemoglobin in his lap carried it to the cells of the lining, like the postage. As the oxygen problem was solved, the number of cells and layers increased; The organs raised; Multicellular organisms have become multi-organisms over time.
Hemoglobin work capacity is good only when oxygen is abundant. If there is less oxygen, it works! In octopus-like organisms where oxygen levels are low, hemoglobin instead of hemoglobin is directly soluble in the blood. Like many insects, these build up the ducts into the body, delivering oxygen to the organs!
Hemoglobin is a dangerous compound, however beneficial for organisms! Par-ferrine is not originally a natural chemical. The utility of the nature par-fairin has been incorporated into a single cell. Thus, leaving the par-faerine free can hurt the body’s organs. That is why our bodies surrounded the globin fort with para-fyrin and bound the hemoglobin into the red blood cells. Red blood cells work for about 120 days. When they break, the hem and the globin become different. Since free heme is dangerous, the liver binds the heme with a special chemical called haptoglobin, turning it into a green chemical called biliverdin. Free heme can lead to a number of health problems if this work can fluctuate. Thus, the design of nature, which binds the useful but dangerous heme into the protein wall and secured it in a red blood cell, is astonishing; Like a magic wand that kept the demon in its line!
Blood color of some lizards in New Guinea Province Biologists have found that biliverdin is replaced by hemoglobin in their blood. This bilivardin is not capable of carrying oxygen! However, it is not known why biliverdin is retained by their bodies! It is estimated that biliverdin probably protects those lizards from something in the area.
Altogether, scientists who had been on the verge of hemoglobin in the Antarctic ice-fish blood had to go on a biopsy. However, the question of no hemoglobin in ice-fish has yet to be answered. Probably at some point in the evolution of genetic hazards, the process of producing hemoglobin in ice-fish may have been disrupted. However, the coldest water in the area has more oxygen than usual. Thus, ice-fish should be able to enlarge the gills, make the skin more absorbent, and direct oxygen through them. The mission of nature is to deliver oxygen to the organism. It needed the help of a dangerous compound called heme. In this case, the supply of oxygen without the hinge of the ice-fish hem must have been natural. Ice-fish further adds to the scientists’ argument that nature chooses less risk between high-risk hazardous processes and low-efficiency tasks. However, nature does not hide the hemoglobin-producing genes from their bodies. The idea of nature can be understood by a human being; But it is impossible to fully grasp its immense potential!
