Lysosomal pool of free-amino acids
Biochemical and Biophysical Research Communications, 1981Abstract Free (non-protein) amino acids were measured in whole rat liver and in unmodified lysosomes which were prepared from rat liver by the technique of free-flow electrophoresis. Significant intralysosomal pools of threonine, serine, valine, cystine, methionine, isoleucine, leucine, tyrosine, phenylalanine, lysine and arginine were found.

Free Amino Acid Content of Perilymph
Archives of Otolaryngology - Head and Neck Surgery, 1971The free amino acid content of horse perilymph, cerebrospinal fluid, and blood serum was comparatively studied. The results obtained show clear-cut differences between the three fluids, and suggest that perilymph may be considered as a biological fluid with its own specific characteristics, probably correlated to the metabolism of its secreting ...

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.

The free amino acids in Trichomonas foetus
Experimental Parasitology, 1962Abstract The free amino acid content of protoplasmic extracts of Trichomonas foetus was determined by unidimensional polychromatic and two-dimensional paper chromatography to include cystine-cysteine, aspartic acid, glycine, serine, glutamic acid, threonine, alanine, tyrosine, leucine-isoleucine, ornithine, lysine, arginine, valine, methionine ...

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.

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 ...

Peptides (Bound Amino Acids) and Free Amino Acids
1955The term “peptide” as distinct from “protein” has come to be reserved for compounds having molecular weight less than, at most, 10,000 or, if of higher molecular weight, having unusually simple amino acid composition. Natural compounds so far shown unequivocally to belong to this class do not exhibit denaturation in its usual sense or, particularly ...

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-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.
