Apolipoprotein C-III also known as apo-CIII is a protein that in humans is encoded by the APOC3 gene.Apo-CIII is secreted by the liver as well as the small intestine, and is found on triglyceride-rich lipoproteins such as chylomicrons, very low density lipoprotein (VLDL), and remnant cholesterol.,

ApoCIII is a relatively small protein containing 79 amino acids that can be glycosylated at threonine-74.
