LRAT (Lecithin Retinol Acyltransferase): LRAT is essential for the metabolism of vitamin A, catalyzing the esterification of all-trans-retinol into all-trans-retinyl esters, a storage form of vitamin A. This process is crucial for vision, immune function, and cellular differentiation. Deficiencies or mutations in LRAT can lead to retinal diseases and impairments in immune response, emphasizing its role in vitamin A homeostasis and overall health....
