The metabolism and glutamic acid content of rat brain in relation to thiopentone anaesthesia

in recent years, great attention has been paid to the quality of eaten meat and its products. There have been launched a lot of promotional campaigns aimed at providing opportunities for the consumption of traditional products. Based on the experiment, a significantly higher protein content was found in sausages produced by large producers (24.73 ± 1.98%). The fat content was significantly higher in traditional ham (16.25 ± 14.47%), compared with local ham (4.38 ± 2.26%) and the mass (9.29 ± 5.25%). The samples of traditional and local ham had a significantly higher salt content (3.31 ± 0.72 and 2.90 ± 0.54%, respectively). No dye compounds were detected in any of the tested samples. There were no statistically significant differences in hydroxyproline and l‑glutamic acid content between traditional and conventional samples of meat products. Analysis of nitrate (V and III) showed a statistically significant difference in the average contents of these compounds. Significantly higher levels of nitrates were revealed only in traditional ham samples (12.60 ± 8.08 mg NaNO(V)/kg and 17.53 ± 27.91 mg NaNO(III)/kg of the product, respectively), wherein there was a large variation in the content of these compounds in the samples.

Amino Acid Component

Abstract The oocytes of the marine goby Pomatoschistus minutus were analyzed for their amino acid content. Most of the amino acids exist as protein, only a little part is free or peptide-bound. Among the protein-bound amino acids, high levels of glutamic acid, proline, alanine, aspartic acid, valine and leucine were detected. These represent more than 60% of the protein amino acids. Among the free acids, glutamic acid, serine and alanine, are dominant. There are no certain proofs of the occurrence of peptide pools in the oocytes of Pomatoschistus minutus.

Phosphate Medium

Rat brain slices respiring in a Krebs–Ringer phosphate medium were found to incorporate glycine-2-C14and DL-glutamic acid-1-C14into the protein.The addition of succinate as the substrate reduced the incorporation of glycine-2-C14into the protein of brain slices. The addition of glutamic acid, glutamine, and methionine sulphoxide into the glucose Krebs–Ringer phosphate medium inhibited the incorporation.The incorporation was also inhibited by 2,4-DNP in concentrations that do not decrease oxygen consumption.The respiration and the incorporation of glycine-2-C14were inhibited progressively with an increase in the concentration of isomytal, azacyclonol, chlorpromazine, and acetylpromazine. In the presence of succinate as the substrate these drugs did not inhibit the respiration of brain slices.
