Lipofuscin, the age pigment.
Lipofuscin is the fluorescent mixture of compounds that accumulates increasingly with age in human tissues, including the pigment epithelium of the retina. A substantial component of lipofuscin has been identified in the retina as N-retinylidene-N-retinylethanolamine. This compound presumably is derived from the reaction of retinaldehyde with the membrane lipid phosphatidylethanolamine.
