Freeing of Amino-acids from Proteins
Nature, 1965THE large amount of free amino-acid which surrounds haemoglobin freshly released from red blood cells cannot be dialysed away from the protein even after vigorous washing (48 h, running water). The amino-acids still released after such washing may come from (a) metabolism of bacterial contaminants, (b) cellular enzymes, (c) amino-acids secondarily ...

Free Amino Acids in Mammalian Tissue
Acta Physiologica Scandinavica, 1951Summary.1. Free amino acids in tissues form different groups. Some acids are present in high relative concentrations in blood serum as well as in all tissues investigated. Other acids are absent from blood serum but present in one or more of the tissues. Some acids are present in high relative concentrations in certain organs only.2.

Free Amino Acids in Human Saliva
Journal of Dental Research, 1973By the use of thin layer chromatographic techniques and exchange column chromatography, 20 free amino acids were found in human saliva. No qualitative or semiquantitative differences in the amino acid content were observed among caries-susceptible and caries-resistant individuals 20 to 30 years old.

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 ...

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 AMINO ACIDS IN DEVELOPING RAT RETINA
Journal of Neurochemistry, 1974Abstract—During postnatal growth the free amino acids pattern of rat retina differs at various developmental stages. The adult level for individual amino acids is reached on the 30th day of maturation. During differentiation the taurine, glutamic acid, GABA, glutamine, aspartic acid, glycine arginine, methionine and histidine levels increase while ...

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.

Free Amino-acids of Some Fungi
Nature, 1960THE nature and amounts of free amino-acids in higher plants are becoming relatively well known since the advent of paper chromatography. However, few investigations of amino-acids in the Cryptogams have been made. Fowden1 has studied the amino-acids of certain algae, Mansford and Raper2 those of Mucor mucedo, Fluck and Richle3 those of Fusarium ...

Free amino acids in germinated wheat
Journal of the Science of Food and Agriculture, 1979AbstractWheat was germinated at three different temperatures (10, 16.5 and 25°C) to examine the changes in free amino acid levels. The free amino acid content after 122 h of germination was respectively 4 x, 10x and 7x that of the sound wheat at ‘0 h ’Glutamine and proline showed the largest increases.
