Composition and content of free amino acids of sublittoral red algae from Murmansk coast of the Barents Sea.

Data on the content of free amino acids (FAA) in four species of red algae are presented. The content of 20 amino acids was determined in the composition of FAA of the studied species. The largest amounts contained glutamic and aspartic acids, alanine, proline and taurine. The studied algae do not differ in the qualitative composition of protein amino acids, but differ in the presence and content of nonprotein ones. The content of most of the FAA and their summ was the highest for Phycodrysrubens, and in Palmaria palmatathe smallest.
