Eumelanin-driven production of molecular hydrogen: A novel element of skin defense?
1University of Novi Sad, Lovcenska 16, 21000 Novi Sad, Serbia.
Abstract:
Molecular hydrogen (H2, dihydrogen) has been recognized as a unique cell protectant. Dihydrogen protects tissues against oxidative injuries by selectively reducing reactive oxygen species (ROS). It seems that melanin, natural pigment of skin and hair, might produce endogenous hydrogen. The protective role of skin melanin (eumelanin) could be due to its capacity for molecular hydrogen production. An effective pooling of dihydrogen by eumelanin should be considered as a novel element of skin defense system against oxidative stress-related disorders.

Pigmentation
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Introduction to the Integumentary System
The skin, which is the primary organ of the integumentary system, consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous tissue). The epidermis is the...
Cells of the Epidermis
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...
