Retinol Binding Protein (RBP) is a protein that plays a crucial role in transporting vitamin A, also known as retinol, from the liver to various tissues in the body. It binds to retinol and ensures its delivery to cells where it is needed for essential functions, such as vision, immune response, and skin health. RBP is produced primarily in the liver and is essential for maintaining adequate levels of vitamin A in the bloodstream. A deficiency in RBP can lead to impaired vision and other health issues related to insufficient vitamin A, highlighting its importance in overall well-being.
