As you can see, these red balls have different alphabets written on them representing blood group O, A, B and AB respectively. Also, there are also hexagons with different with each unique colour representing a unique sugar; Purple hexagon represents the sugar N acetyl-galactosamine, maroon hexagon represents the sugar Fucose, blue hexagon represents the sugar N acetyl-glucosamine and the peach coloured hexagon represent the sugar, Galactose.
These groupings of different sugars to around the red blood cells from different antigens which are then classified as antigen O, A, B and AB according to the sugar combination around the red blood cell. If you look at this image again you’ll understand what I’m trying to say, the type O antigen consists of Fucose, N acetyl-glucosamine, and two Galactose. If you take a look at the Type A antigen you’ll notice that the sugar components that type O is comprised Type O are the same with type A just with something extra which is the purple hexagon that represents the sugar N acetyl-galactosamine. Type B antigen also has the same sugar composition with type O but Instead of having two Galactose like type O it has three Galactose. Type AB antigen as the name may imply, is a combination of type A and type B Antigen on one red blood cell with type A on the right and type B on the left accordingly.
If we want to change from either of these types to type O, excluding type AB as you can see in the image above would be a lot of trouble. Looking at the image the most realistic way to change type A to type O is by removing the purple hexagon which represents the sugar N acetyl-galactosamine and to change type B to type O is by adding another molecule of the sugar, galactose to the picture which would seem to cause a little problem too like the type AB. The more feasible blood group that can be conveniently changed to type O at this point is type A which requires, simply removing the purple hexagon representing N acetyl-galactosamine from the picture. This process of removing N acetyl from type A antigen is required to be done in a very conducive environment so that the red blood cell is not affected in the process. This is where the enzymes come in, as they are the naturally existing and most popular biological catalysts.

These scientists discovered that enzymes are the element to use in executing this experiment but the question was where they could find a perfect enzyme that would do for this experiment. They started to carry out research and discovered that these sugars attached to the red blood cells can also be found in the gut of humans.
The image above is a simple sketch of the human gut or the human gastrointestinal tract; In this gastrointestinal tract enzymes, sugars and bacteria are contained. These sugar structures stick to the gastrointestinal wall and the bacteria do the same and in the process, these bacteria feed on these sugar structure attached to the gut wall, as they feed these sugar structures are broken down with the help of enzymes present in the gut wall. These scientist carrying out the study thought that as these bacteria were feeding on the sugar and causing them to be broken down, these sugars were also breaking down and sticking to others which made them curious and they started testing enzymes present in the human gastrointestinal tract that helped in making that process a success. During the course of testing and experiments, they discovered a class of enzyme that was tested and proven to be as much as 30 per cent more efficient than the rest of the enzymes that they had found an tested.

His father was a type AB- minus and did not have anyone around with the perfect blood type and the local hospital he was taken to at that time was out of blood, before they could find someone or where to get his blood type, his father had already given up the ghost. Another story related to this one is of my friend who lost his sister who was O- and didn’t have anyone with her blood type to donate blood to her. The hospital she was taken to was of no use because they could not find her a donor or get from the blood bank to him on time. There are many cases and sad stories of people dying because of the scarcity of blood due to their blood type or group which could be a thing of the past if the experiment of Dr Steven Withers and his group of Medical Practitioners turns out to be a huge success.

August 20th Withers, however, said that the enzymes his team discovered could eventually be used in the clinic. It would be possible to alter blood on a bag-by-bag basis, he said.
"You could see this being put into the bag at the time of collection, just sitting there doing its job," Withers said during the press conference. The next step, though, will be investigating the enzymes for safety — a project Withers and his colleagues have already begun in collaboration with hematologists and Canadian Blood Services, the nonprofit that manages Canada's supply of donor blood.
It could be eventually used but hasn’t been tried yet. The human body is much complex and may not give us the same results gotten from the experiment in the laboratory. I hope it turns out to be a success

If this is successfully implemented and becomes widely available and acceptable, it will be a major stride forward for science.
