Question

Serum albumin is the main protein in the blood. It serves as a carrier in the blood for molecules which are not totally soluble in water. Albumin also helps maintain the fluid balance in the body. Sometimes, it is also measured in blood samples as an indicator of overall protein status. Based on your knowledge of protein turnover, suggest at least one reason why albumin is used as an indicator of protein status that is better than measuring amino acid concentrations in the blood.

Answer 1

1. The amino nitrogen of blood filtrate varies than the normal.
2. The quantittative analysis of amino acids in blood is quit difficult compared to blood serum albumin.
3. Turner used the method of vividiffusion to isolate the crystalline amino acid from blood stream for the first time.
4. The quantity of amino acid present in the blood give different test results with different analytical method used (amino acids are more concentrated than blood serum)
5. Human serum albumin is the most abundant protein found in blood plasma (55%)
6. A total serum test give result of total amount of blood protein present ( albumin & globulin)
