Abstract

The protein content in the dry body weight of the starfish Odontaster validus is 30%. The composition of amino acids is characterized by a very high level of glycine (27%). Glutamic acid (Glu) in a concentration of 10 mM/liter in seawater causes an increase in the metabolic rate of starved O. validus. As the period of starvation increases, this reaction is enhanced. A two-hour exposure to kynurenic acid (Kyn) in a concentration of 0.1 mM/liter blocks the reaction to glutamic acid.
