Metabolic Significance

By using the automatic amino acid analyzer (model 120 B, Beckman) the free ninhydrin-positive components in the methanol extracts of Drosophila melanogaster were fractionated. Compared to the conventional paper partition chromatography the great advantage of this technique is the distinct separation of such amino acids like leucine, isoleucine, phenylalanine, valine, methionine, γ-amino-butyric acid as well as the basic components ornithine, lysine, histidine and arginine. Furthermore, the occurrence of phosphoserine, tyrosine phosphate, ethanolamine, phosphoethanolamine and glycerophosphoethanolamine was identified. The metabolic significance of these substances is discussed.

Amino Acid Analyzer

The contents of free amino acids(FAAs) in Parapenaeopsis hardwickii, Penaeus vannamei and Macrobrachium nipponensis was analyzed by using the automatic amino acid analyzer in this study. The results show that the sequence from the highest to the lowest in total amount of FAAs is Parapenaeopsis hardwickii, Penaeus vannamei and Macrobrachium nipponensis. SPSS(19.0) results indicate that except for Cys, Lys and Thr, FAAs in these three shrimps are significant different (p<0.05), and all of them have a high concentration of Arg, Gly and Pro and a low concentration of Asp and Cys. The content of Gly in shrimp is higher than that of crab and oyster. Both Arg and Gly significantly contribute to the taste of the three shrimps, Glu and Pro play an important role in the flavor of Parapenaeopsis hardwickii and Penaeus vannamei, while not as significant as in the taste of Macrobrachium nipponensis. Composition modes of FAAs which make major contributions to flavor in marine shrimps, Parapenaeopsis hardwickii and Penaeus vannamei, are similar, but different from freshwater shrimp, Macrobrachium nipponensis.

Introduction. Ischemic heart disease is the leading nosology calunit in the structure of cardiovascular diseases interms of disability and mortality among the population of Ukraine. The purpose. To improve the treatment of patients with stable angina by studying the effect of L-arginine on the balance of essential amino acids in blood plasma. Material and methods. It was examined 85 patients with stable angina. They were divided into two groups: group Ipatients received antianginal basic therapy, group II patients received basic antianginal therapy and L-arginine. The amino acid spectrum of patients' blood plasma was studied by ion-exchange liquid column chromatography, using an automatic amino acid analyzer T-339 Microtechna (Czech Republic, Prague). Results and discussion. In patients with stable angina who received basic therapy and L-arginine, in contrast to patients who received only basic therapy, plasma levels of arginine became normalized, which probably contributes to the synthesis of NO. The level of valine, leucine and isoleucine, which provide the synthesis of acyl-CoA and succinyl-CoA, became also normalized.Conclusion. Administration of L-arginine to patients with stable angina together with antianginal therapy helps to correct plasma amino acid imbalances, which is likely to effectively affect the course of the disease and prognosis.
