FREE AMINO ACIDS IN SOME AQUATIC INVERTEBRATES

Aquatic Invertebrates

Animals are important and conspicuous elements inPacifi c Island ecosystems. They are crucial to the fl ow of energy and nutrients within ecosystems and they strongly infl uence, and in some cases control, the species composition and population structure of communities. Determining which animal species are present in an area and what they do is crucial to understanding how ecosystems function a...

Free Amino Acids as Regulators of Osmotic Pressure in Aquatic Insect Larvae

Microanalytical techniques are used to show that organic molecules play an important role is osmoregulation. Changes in the inorganic ion composition of haemolymph from fourth instar larvae of Aedes aegypt} are correlated with the changes in the concentration of organic ions. Free amino acids have a significant role in regulating haemolymph osmotic pressure with respect to the osmotic pressure ...

Contents of Free Amino Acids in Mushrooms

The fruit bodies of 113 kinds of mushrooms were examined by amino acid analyzer to determine 20 free types of protein amino acids and 11 non-protein amino acids . (1) Though considerable difference was often found among species of mushroom, the average of total free amino acids was 213μ mol/g dry matter. (2) It was found that the amount of alanine, glutamic acid and glutamine was very high and ...
