Study Notes
Plasma Proteins
- The approximate concentration of total proteins in human plasma is around 60-80 g/L.
- The main function of plasma proteins related to osmolarity is to attract and hold water in the blood vessels.
Synthesis of Plasma Proteins
- The liver primarily synthesizes all types of plasma proteins except gamma globulins.
Carrier Proteins
- Many plasma proteins act as carrier proteins for lipids, hormones, and vitamins.
Synthesis of Gamma Globulins
- B-lymphocytes (B-cells) are responsible for synthesizing gamma globulins.
Functions of Plasma Proteins
- One function of plasma proteins is to regulate osmotic pressure.
- One function of plasma proteins is to transport lipids, hormones, and vitamins.
- One function of plasma proteins is to provide defense against infection and disease.
- The function of plasma proteins does NOT include platelet aggregation.
Plasma Composition
- The approximate percentage of water in the plasma of blood is 92%.
- The liver is primarily responsible for synthesizing most types of plasma proteins.
- Inorganic matters in plasma solids include electrolytes, such as sodium, potassium, and chloride, but do NOT include oxygen.
