Question

Quizplus · Accepted Answer

Retinoic acid is the form of vitamin A that is involved in gene expression. It acts as a ligand for nuclear receptors that regulate gene transcription. Retinol and retinal are precursors that are converted to retinoic acid in the body, and retinol-binding protein is a carrier protein for retinol. Opsin is a protein in the retina that interacts with retinal to enable vision.
