Variación en la concentración de aminoácidos tipo micosporinas en macroalgas de las regiones de Valparaíso y Magallanes, Chile

The synthesis and accumulation of photoprotective compounds, as mycosporine-like amino acids (MAAs), is a mechanisms of protection against UV radiation. The photoprotective compounds synthesis can be induced under different stress factors, including intensity and spectral quality: PAR or UVR. The ai...
