Serum amyloid A

Serum amyloid A (SAA) is a group of proteins which flow in the blood. They are related to "good cholesterol". Almost all animals have SAA's. SAA's are made in and controlled by the liver. They move cholesterol to the liver. SAAs increase during inflammation. Doctors and scientists think that SAAs may be part of amyloidosis, heart disease, and rheumatoid arthritis.
