Verified step by step guidance

Understand the context: Human plasma is the liquid component of blood that contains water, electrolytes, nutrients, hormones, and various proteins. Proteins found in plasma typically serve functions such as immune defense, clotting, and maintaining osmotic balance.

Review the listed proteins: Immunoglobulin G (IgG) is an antibody involved in immune defense, fibrinogen is a clotting factor, and albumin helps maintain osmotic pressure and transport substances. These are all normal components of plasma.

Consider hemoglobin: Hemoglobin is a protein responsible for oxygen transport in red blood cells. It is not typically found in plasma under normal conditions because it is confined within red blood cells.

Clarify the distinction: Hemoglobin may appear in plasma only under pathological conditions, such as hemolysis (rupture of red blood cells), but it is not a normal component of plasma.

Conclude: Based on the information, hemoglobin is the protein that is NOT normally found in human plasma.
