Pathological Conditions

Abstract Free amino acids in the tonsils of 20 individuals were measured column chromatographically. Those always found in readily detectable amounts included O-phosphoserine, taurine, O-phosphoethanolamine, aspartic acid, hydroxyproline, threonine, serine, glutamic acid, proline, glycine, alanine, α-amino-n-butyric acid, valine, cystine, methionine, isoleucine, leucine, tyrosine, phenylalanine, ornithine, γ-amino-butyric acid, lysine, histidine, and arginine. Results were compared for three clinical pathological groups and for four age groups. Some abnormal values may result from the pathological conditions.

Partial Sterilization

1. An investigation has been made into the changes that take place in the free amino-acid pattern when kale-water slurries are allowed to ferment under conditions of (a) aeration, (b) anaerobiasis and (c) partial sterilization with sulphur dioxide.2. It has been found that, with aerated mixtures, the loss of free amino-acids is virtually complete within 2 weeks, while there is only a slight loss with the anaerobic mixtures. With mixtures containing sulphur dioxide no loss of amino-acids occur.3. The formation of α-amino butyric acid possibly from threonine has been noted.

Protein Amino Acids

The free and protein amino acid patterns present in the leaves of the species of the genus Gossy pium were determined. The presence or absence of the free amino acids except for glycine and γ-amino butyric acid did not appear to be of value for separation of the species. However, the patterns of the protein amino acids varied between the genomes, and seemed to separate the species. These patterns were separated into groups similar to those found for the DNA-base ratios and the cytotaxonomic grouping of the species.

Applied Nitrogen

Needles of grand fir, Abiesgrandis (Dougl.) Lindl., were analyzed to determine: (1) how various forms of nitrogen fertilizer affect amino acid composition, and (2) whether amino acids in the needles differ from those in stem bark (determined in a previous study). Young grand fir were grown in a shadehouse and free amino acids were analyzed four times from May to August, using thin-layer electrophoresis and chromatography. The effects of foliar-applied nitrogen fertilizer on needle amino acids depended on the form of nitrogen. Urea or ammonium nitrate promoted large increases in arginine, glutamine, alanine, lysine, and γ-amino butyric acid, whereas calcium nitrate caused smaller increases. The occurrence of several trace amino acids also varied with the form of nitrogen. Comparison of needle amino acids with those in the stem of unfertilized trees revealed that levels of total amino nitrogen, arginine, glutamic acid, and glutamine were much greater in the stem bark than in the needles, but levels of γ-amino butyric acid and alanine were higher in needles. Traces of aspartic acid, ornithine, and tyrosine were found in the needles, but not in the stem.

The haemolymph of eight ages during larval development of the two female castes of the honeybee, Apis mellifera L., were examined for free amino acids. Twenty-seven identified free amino acids and three unidentified ninhydrin-positive compounds were detected in both castes by the technique of thin-layer chromatography described. The amino acids identified were aspartic acid, cystine, glutamic acid, asparagine, glycine, serine, taurine, ornithine, threonine, lysine, alanine, arginine, histidine, gtutamine. β-alanine, hydroxyproline, proline, methionine, methionine sulphone and (or) sulphoxide, α-amino-n-butyric acid, γ-amino-n-butyric acid, tyrosine, tryptophan, valine, phenylalanine, leucine, and isoleucine.The general trend in both castes was for the total amino acid concentration first to increase and then, around the third day in workers and the fourth day in queens, to undergo a steady decrease with age.Aspartic acid concentration varied so greatly between the two castes that it is suggested as a criterion of dimorphism.The significance of these results is discussed in relation to female dimorphism.
