Plant biomass represents a rich nutrient resource for microorganisms. This includes both structural chemical constituents that require degradation and directly accessible soluble compounds such as amino acids. The concentration of free amino acids in plant litter is dynamic and is significantly affected by degradation patterns and leaching.

Free Amino Acids in Tetrahymenidae
The Journal of Protozoology, 1963SYNOPSIS. Free amino acids in extracts of a number of tetrahymenid genera, species and strains of Tetrahymena pyriformis were separated by a combination of paper electrophoresis at pH 1.9 and descending paper chromatography with lutidine as solvent. Ethanol extracts of ciliates cultured at temperatures of either 15°, 25° or 35°C were used.

Free Amino-acid Content of the Lymph
Nature, 1956WE have been studying the free amino-acids of the blood and urine by quantitative paper chromatography1. This method also offered the possibility of extending our researches on lymph and of comparing the free amino-acid content of lymph and blood obtained from different areas.

Comparative Radiolability of Amino Acids of Proteins and Free Amino Acids
Radiation Research, 1964Despite considerable work in the field of radiation chemistry of amino acids and proteins, the mechanisms of radiation damage to free amino acids and amino acids of proteins are not well understood, and more knowledge of the generalities of comparative radiolabilities of free amino acids and amino acids of proteins is needed.

Free radical-mediated oxidation of free amino acids and amino acid residues in proteins
Amino Acids, 2003We summarize here results of studies designed to elucidate basic mechanisms of reactive oxygen (ROS)-mediated oxidation of proteins and free amino acids. These studies have shown that oxidation of proteins can lead to hydroxylation of aromatic groups and aliphatic amino acid side chains, nitration of aromatic amino acid residues, nitrosylation of ...

Are dissolved free amino acids free?
Microbial Ecology, 1984Microbial assimilation of 3 amino acids (glutamic acid, alanine, and ornithine) was characterized in 3 lakes and 2 marine stations using the Michaelis-Menten kinetic approach. The calculated Kt + Sn concentrations were related to chemical concentration measurements of dissolved free amino acids (DFAA) to evaluate the biological and the chemical ...

Free amino acids in the pregnant uterus
American Journal of Obstetrics and Gynecology, 1969Abstract Free amino acids in seven pregnant human uteri were quantitatively determined and compared to tissues from nonpregnant patients. Only uterine glycine and lysine were found to decline significantly. Other amino acids generally increased. Serum amino acids from pregnant and nonpregnant patients were also compared, and uterine-serum ratios ...

Free amino acids in spider hemolymph
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2008We examined the free amino acid composition of hemolymph from representatives of five spider families with an interest in knowing if the amino acid profile in the hemolymph of orb-web-building spiders reflects the high demands for small organic compounds in the sticky droplets of their webs.

Axoplasmic transport of free amino acids
Brain Research, 1973Abstract (1) Following the injection of l -[14C]proline into one eye in carp, the label appeared in the contralateral optic nerve via axoplasmic flow. As reported previously, protein-bound activity showed faster and slower axoplasmic transport. Labeled free proline appeared in nerve before labeled protein and thus did not originate from labeled ...

Free amino acids in the caiman and rat
Comparative Biochemistry and Physiology, 1966Abstract 1. 1. Free amino acids and total ninhydrin reactive compounds were determined in alcoholic extracts of the tissues of fasting and fed caimans and fasting rats. 2. 2. Total ninhydrin reactants exceeded the sum of amino acids on the chromatogram several-fold. 3. 3.
