Study Notes

Functions of Plasma Proteins

Albumins maintain osmotic pressure in blood plasma, regulating fluid balance between blood and tissues.
They transport various substances, including hormones, vitamins, and drugs, aiding in nutrient distribution.

Coagulation and Wound Healing

Fibrinogen, a plasma protein, confines clot formation to the area of a wound, preventing excessive bleeding and ensuring localized healing.

Health Implications of Protein Deficiency

A deficiency in circulating α1-antiproteinase can lead to unchecked enzyme activity, resulting in tissue damage, lung disorders (e.g., emphysema), and accelerated aging of tissues.

Role of Plasma Ceruloplasmin

Insufficient plasma ceruloplasmin levels can cause Wilson's disease, leading to copper accumulation in tissues, liver damage, and neurological disorders.

Function of Antithrombin

Antithrombin functions as a natural anticoagulant that inhibits thrombin and other clotting factors, regulating blood coagulation and preventing excessive clotting.
