Mycosporine-like amino acids have biological activities in human cells and animals involving gene regulation and activation of signaling pathways in addition to UV-protective activity.
Because harmful irradiation induces oxidative stress through radical-propagating processes, mycosporine-like amino acids are expected to play an additional role in antioxidant systems, and the review focuses on MAAs with radical scavenging activities.
Mycosporine-like amino acids are utilized in a wide variety of organisms including prokaryotic and eukaryotic microorganisms inhabiting aquatic, terrestrial, and marine environments.
Mycosporine-like amino acids are water-soluble molecules that absorb UV-A and UV-B radiation and disperse the energy as heat.
Mycosporine-like amino acids exhibit broad structural diversity with molecular weights spanning 188 to 1050 Daltons.
The review presents mycosporine-like amino acids as stable and fundamental molecules that allow organisms to live under UV irradiation and as primary sunscreens that reduce short-wavelength light.
