General description

Melanin is a ubiquitous and prominent pigment responsible for color of skin, hair and eyes. Melanin is classified into eumelanin and pheomelanin. Eumelanin is black to dark brown pigment and is present in black hair and retina of the eye. Pheomelanin is yellow to reddish brown pigment present is red hair and red feathers. Melanins are high molecular weight pigments synthesized from phenolic or indolic precursors and is widely present in animals, plants and microorganisms.

Application

Melanin from Sepia officinalis has been used:
  • as a natural pigment for Raman spectroscopy measurements
  • in competitive enzyme linked immunosorbent assay (ELISA) for the characterization of phage antibodies
  • as an external standard for spectrophotometrically determining the melanin production in B16F10 cells

Biochem/physiol Actions

Melanin scavenges active chemical species and acts as a sunscreen.

Melanin pigments are broadly distributed in nature - from bacteria to fungi to plants and animals. However, many previous attempts to identify melanins in spiders were unsuccessful, suggesting that these otherwise ubiquitous pigments were lost during spider evolution. Yet, spiders

Objective measurements of melanin can provide important information for differentiating melanoma from benign pigmented lesions and in assessing pigmentary diseases.
