Albumin and the SkinAlbumin Molecular Structure

Although albumin is the principal blood protein, it is also located in every tissue and bodily secretion with approximatley 50% of the body's total albumin located outside the circulatory system (extravascular).  The skin is the largest body organ comprising 19% of the total mass, but suprisingly, contains almost 50% of the extravascular albumin.  Clearly, albumin plays many important roles in this specialized organ.
