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.

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 ...

Extraction of free amino acids
American Potato Journal, 1988A solvent is percolated through the sample of freeze-dried potatoes in a column until no more free amino acids are extracted. The simple method can operate unattended and with other materials. NH3 and ARG are the last to be removed. Maillard intermediates survive.

Biochemical Systematics and Ecology, 1980
Abstract Pollens from Pinus canariensis, P. nigra, P. pinaster, P. pinea, Castanea sativa, Magnolia grandiflora, Olea sativa cv frantoio , cv itrana , cv pisciottana were examined for their free amino acid composition. A large amount of proline was found in all species; pollens of Olea also contain a large amount of serine.

[Free amino acids in calf embryos].
Bollettino della Societa italiana di biologia sperimentale, 1979In this work have been reported the research results tending to establish the free amino acidis concentration, existing in the calf embryos. The free embryonal amino acidis composition has been determined through an analysis effected with "Amino Acid Analyzer".

Coherent manipulation of free amino acids fluorescence
Physical Chemistry Chemical Physics, 2012Coherent manipulation of molecular wavepackets in biomolecules might contribute to the quest towards label-free cellular imaging and protein identification. We report the use of optimally tailored UV laser pulses in pump-probe depletion experiments that selectively enhance or decrease fluorescence between two aromatic amino acids: tryptophan (Trp) and ...
