Adenylate concentration and energy charge in different thallus regions and after UV radiation in brown, red and green algae ...
A method was developed to extract adenine nucleotides AMP, ADP, and ATP from marine macroalgal tissue to gain information on the cellular energy charge. Quantification was carried out by high performance liquid chromatography (HPLC). Three species from the rocky shore of the island of Helgoland (Ger...
