What is not a major function of the plasma proteins in the blood?
It seems there was more to this question, like some multiple choice answers. I guess the best way to approach this question is to give you a summary of the types of blood proteins and their functions. From that, you should be able to figure out your answer. Blood is made up of about 7% proteins. Some of the main types are albumin with serves to maintain osmotic balance and to help transport other molecules in blood. Globulins or immunoglobulins which are classified as alpha, beta and gamma serve a function of immunity. The third type is fibrinogen, which is the proteins involved in blood clotting.
