Chemical composition of the Antarctic starfish Odontaster validus and its reaction to glutamic and kynurenic
acids. T. Janecki, S. Rakusa-Suszczewski (Department of Antarctic Biology, Polish Academy of Sciences, Ustrzycka
10/12, 02-141, Warsaw, Poland)
The protein content in dry body mass of the starfish Odontaster validus is 30%. Amino acid composition is characterized by a very high level of glycine (27%). Glutamic acid in a concentration of 10 mmol/liter in sea water causes an
increase in metabolic rate of starved O. validus. With increasing starvation period, this reaction is enhanced. A two-hour
exposure to kynurenic acid in a concentration of 0.1 mmol/liter blocks reaction to glutamic acid. (Biologiya Morya,
Vladivostok, 2004, vol. 30, no. 5, pp. 406–408).
Key words: glutamic acid, kynurenic acid, starfish, Odontaster validus.
