Melanins and melanogenesis: methods, standards, protocols
Despite considerable advances in the past decade, melanin research still suffers from the lack of universally accepted and shared nomenclature, methodologies, and structural models. This paper stemsExpand
Current challenges in understanding melanogenesis: bridging chemistry, biological control, morphology, and function
Melanin is a natural pigment produced within organelles, melanosomes, located in melanocytes. Biological functions of melanosomes are often attributed to the unique chemical properties of theExpand
Direct chemical evidence for eumelanin pigment from the Jurassic period
Melanin is a ubiquitous biological pigment found in bacteria, fungi, plants, and animals. It has a diverse range of ecological and biochemical functions, including display, evasion, photoprotection,Expand
Ultrastructural organization of eumelanin from Sepia officinalis measured by atomic force microscopy.
Atomic force microscopy is used to investigate the structural organization of eumelanin isolated from the inks sacs of the cuttlefish Sepia officinalis. Deposits of eumelanin on mica reveal a rangeExpand
Ion-exchange and adsorption of Fe(III) by Sepia melanin.
Sepia eumelanin is associated with many metal ions, yet little is known about its metal binding capacity and the chemical nature of the binding site(s). Herein, the natural concentrations of metalExpand

Metal chelation is often invoked as one of the main biological functions of melanin. In order to understand the interaction between metals and melanin, extensive studies have been carried out toExpand
Neuronal pigmented autophagic vacuoles: lipofuscin, neuromelanin, and ceroid as macroautophagic responses during aging and disease
The most striking morphologic change in neurons during normal aging is the accumulation of autophagic vacuoles filled with lipofuscin or neuromelanin pigments. These organelles are similar to thoseExpand
Insights into melanosomes and melanin from some interesting spatial and temporal properties.
Melanosomes are organelles found in a wide variety of tissues throughout the animal kingdom and exhibit a range of different shapes: spheres of up to approximately 1 mum diameters and ellipsoids withExpand
