Mycosporine-Like Amino Acids: Potential Health and Beauty Ingredients [PDF]

, 2017
Human skin is constantly exposed to damaging ultraviolet radiation (UVR), which induces a number of acute and chronic disorders. To reduce the risk of UV-induced skin injury, people apply an additional external protection in the form of cosmetic products

Survey of ultraviolet radiation-absorbing mycosporine-like amino acids in adult females of planktonic copepods

Annals of Tropical Research, 2002
The presence of UV-absorbing rnycosporine-like amino acids (MAAs) from nine planktonic calanoid copepod species were investigated. MAA concentrations from methanol extracts of adult females were analyzed by High Performance Liquid Chromatography (HPLC).

Complementary UV-Absorption of Mycosporine-like Amino Acids and Scytonemin is Responsible for the UV-Insensitivity of Photosynthesis in Nostoc flagelliforme

Marine Drugs, 2010
Mycosporine-like amino acids (MAAs) and scytonemin are UV-screening compounds that have presumably appeared early in the history of life and are widespread in cyanobacteria.

Multiple Roles of Photosynthetic and Sunscreen Pigments in Cyanobacteria Focusing on the Oxidative Stress

Metabolites, 2013
Cyanobacteria have two types of sunscreen pigments, scytonemin and mycosporine-like amino acids (MAAs). These secondary metabolites are thought to play multiple roles against several environmental stresses such as UV radiation and desiccation.

Photochemistry and photophysics of mycosporine-like amino acids and gadusols, nature's ultraviolet screens [PDF]

, 2015
Mycosporine-like amino acids (MAAs) and related gadusols are among the most prominent examples of metabolites suggested to act as UV-sunscreens. This review illustrates how experimental and theoretical studies on model MAAs and gadusol offer a helpful ...

Exploitation of microalgae for the production of biomolecules with emphasis on mycosporine like amino acids (MAA)

Τα μικροφύκη αντιπροσωπεύουν φωτοσυνθετικούς μικροοργανισμούς με υψηλή προσαρμοστικότητα και σημαντικό δυναμικό για τη βιώσιμη παραγωγή βιοδραστικών ενώσεων υψηλής αξίας. Μεταξύ αυτών, τα αμινοξέα που oμοιάζουν με μυκοσπορίνη (MAAs) αποτελούν μια ομάδα δευτερογενών μεταβολιτών χαμηλού μοριακού βάρους, διαλυτών στο νερό, με ισχυρές ιδιότητες απορρόφησης
