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.

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.

[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".

γ-Amino-butyric Acid and Other Free Amino-acids in the Coconut
Nature, 1956γ-AMINO-BUTYRIC acid has been described as present in the aqueous and alcoholic extracts of a number of plant and animal tissues1–7. In the course of studies on the nitrogenous constituents of coconut (Cocos nucifera) endosperm using paper chromatography, I have found this amino-acid to be present in amounts apparently larger than any other amino-acid ...

FREE AMINO ACIDS OF FETAL BRAIN
Journal of Neurochemistry, 1969Abstract— Injection of each of the branched chain amino acids into maternal rats from the 14th to 21st day of pregnancy resulted in increased levels of these compounds in fetal serum. Furthermore, these amino acids were found in high concentration in fetal brain.
