Plasma proteins : 3 major types

[SaintJude]

Plasma protein--3 major types

1. Albumin (responsible for maintaining blood osmolarity)
2. Fibrinogen- (important in blood clot formation)

3. Globulins...do what?

They carry stuff. Hormones like steroids that are not soluble in blood.

What's with all the bloody questions today!

Hemoglobin -> carry oxygen

Hemoglobin -> carry oxygen

Hemoglobin is not a plasma protein. It's inside RBCs.

Globulins include a bunch of different proteins with various functions. You're probably most familiar with immunoglobulins, aka antibodies

Hemoglobin is not a plasma protein--at least in the sense that these are proteins that are solely in the plasma and cannot diffuse across capillary walls.

Red blood cells contains hemoglobin proteins. So hemoglobin is actually an erythrocyte protein

edit: Ah, kaushik replied right before me. Thanks for verifying--you definitely know more about this than I do.

Oops. terribly bad at this.

I think most of the globulins in plasma are immunoglobins (antibodies).
