What protein helps carry fatty acids through the blood?

Albumin is a type of protein that plays a crucial role in the transportation of fatty acids through the bloodstream. It is the most abundant plasma protein in human blood and is primarily synthesized in the liver. Albumin has a high binding capacity for various substances, including fatty acids, which allows it to effectively transport them to different tissues and organs. This function is vital because fatty acids are essential for energy production, hormone synthesis, and cellular structure.

Globulin also carries substances in the blood, but its main role is in immune function rather than fatty acid transport specifically. Hemoglobin is responsible for transporting oxygen in red blood cells, and while it plays a vital role in respiration, it does not pertain to fatty acid transport. Collagen, on the other hand, is a structural protein found in connective tissues, skin, and cartilage, and does not have a function in the transport of fatty acids in the bloodstream.
