The most abundant protein in the human blood plasma is:
Correct Answer:
Albumin
Explanation:
Albumin is the most abundant protein in human blood plasma. It’s produced by the liver and makes up roughly 60% of the total plasma protein, at concentrations around 35–50 g/L in healthy adults. Its main job is to maintain colloid osmotic pressure, keeping fluid inside the blood vessels and preventing edema. Albumin also acts as a versatile carrier, binding and transporting many substances such as fatty acids, bilirubin, hormones, electrolytes, and various drugs. Fibrinogen and the globulin fraction are present but at lower levels; fibrinogen is mainly a clotting factor, and globulins include various transport proteins and immunoglobulins. Hemoglobin is contained within red blood cells, not in plasma. Hence, albumin is the correct answer.
