Study Notes
Albumin in Blood Serum
- Blood serum contains two major protein groups: albumin and globulin
- Albumin is the most abundant circulating protein found in plasma, making up half of the total protein content in a healthy human body
Characteristics of Albumin
- Synthesized in the liver from 585 amino acids at a rate of 9-12 grams per day
- No reserve or storage of albumin in the body
- Average half-life of albumin is 21 days
Structure of Albumin
- Most plasma proteins are glycoproteins, containing either N- or O-linked oligosaccharide chains, or both
- Albumin is the major exception, being carbohydrate-free and not containing sugar residues
