Albumin

Most abundant plasma protein (~35–50 g/L); 66.5 kDa, 585 aa, 3 α-helical domains; synthesised by hepatocytes (~12–14 g/day, t½ ~20 days). Provides ~80% of oncotic pressure; transports FAs, bilirubin, drugs, hormones. Hypoalbuminaemia → oedema, ascites.

Also known as: serum albumin, HSA, human serum albumin, ALB
