What is the total protein content of whole blood of a normal human or mammal including blood cells?
Hey. When I read your question, I thought about the total protein. The total protein is all of the proteins that are in the blood. Determination of the level of total protein in the biochemical examination facilitates the diagnosis of many diseases. In my country, there are test standards according to which their proper concentration is 60 - 80g/l. The circulatory system of an adult human contains about 70-80 ml of blood per kilogram of body weight, so a person with an average body weight has 5 to 6 liters of blood in his body (due to the difference in size and weight, men have an average of a liter more blood than women). Assuming the average value of concentration as 70g/l and the average volume of blood in the human organism - 5.5l, multiplying this we get the result 385g of protein in the blood of the average person.
Blood proteins, also termed plasma proteins, are proteins present in blood plasma. It is approximately 7 gms/ dl
There seems to be about 7% protein in plasma, but the hemoglobin and red blood cells contain quite a bit more. Assuming a hematocrit of 50% and 50% water, that makes about 25% protein in the RBC part for a total of (12 + 7)/2 or about 9.5%. Sound reasonable?
