Glycerol that surrounds a cell virus is like having a body that is unable to rid itself of high cholesterol. When there is too much cholesterol, most often it gets deposited into the arteries and that is when people develop heart disease due to arteries in which plaque restricts blood flow. Also plaque can cause blood clots and limit the supply of oxygen to the brain. So, when you think of this and the effects of glycerol surrounding a cell virus, this means that the virus or plaque in this instance builds up and causes the immune system to be surrounded by a virus that it cannot respond to because it breaks down healthy cell membranes and lymphocytes in the body, because the body's immune system is no longer able to recognize the disease of build antibodies against it. Just as too much cholesterol causes plaque and problems in the heart, brain and liver ect. Cholesterol plaque does not have a cholesterol immunity that prevents it from becoming too high or too low so that it does not develop into an instance of excess plaque buildup. Glycerol functions the same way in that it binds itself to receptors in the body and thus, damages the immune system and it's function because the body does not regulate it on it's own.
Glycerol may be of some good in this world but not when it is a phospholipid surrounding a virus.
What can be done to remove the glycerol component that surrounds a virus? Perhaps ionic solvents can be used as a way to remove the lipid bilayers from a cell virus so that the body's immune system will be more adept to respond to a virus by removing it from the body. Or who knows, one day there may be glycerol inhibitors, used to prevent virus invasion and mechanism for cell rescue in the body!
