To define plant 'nutritional quality' for aphids, the causal basis of the variation in aphid performance between host plants of different developmental ages was explored using the aphids Myzus persicae and Macrosiphum euphorbiae on potato plants (Solanum tuberosum). Both aphid species performed better on developmentally young ('pre-tuber-filling') plants than on mature ('tuber-filling') plants....

The protein quality of the liquid diet Two Cal HN was evaluated by plasma amino acid (PAA) ratio and by chemical score. The PAA test was performed in young healthy men, elderly healthy men, and elderly institutionalized, tube-fed men. In all three groups the PAA ratio for tryptophan was negative, indicating a deficiency of this amino acid in the formula's protein. But the amino acid score for t...

Amino acid composition of the whole body tissue of Axillary seabream (Pagellus acarne) was determined. Fish was catched from Dardanelles (April 2013) via fishing line. The most abundant amino acid was Glutamic Acid (11.0 g/100 g crude protein) and Valine was the most abundant essential amino acid (6.2 g/100 g crude protein). The total essential amino acid content was 32.3 g/100 g crude protein ...

  Eviscerated sea bass, Dicentrarchus labrax were irradiated by Cobalt-60 at commercial irradiation facility at dose of 2.5 and 5 kGy at 2–4°C. The influences of the irradiation on proximate, fatty acid and amino acid composition in cultured sea bass were investigated. Significant differences (P < 0.0.5) were found between non-irradiated and irradiated sea bass in terms of moisture, protein, fa...

Amino acids are important sources of soil organic nitrogen (N), which is essential for plant nutrition, but detailed information about which amino acids predominant and whether amino acid composition varies with elevation is lacking. In this study, we hypothesized that the concentrations of amino acids in soil would increase and their composition would vary along the elevational gradient of Tai...

The proximate composition of pen shell adductor muscle (PSAM) was determined, and its nutrition value was evaluated. Proximate composition analysis indicated that PSAM contained 91.07% (w/w) protein, 5.77% (w/w) ash, and 2.46% (w/w) fat. Calcium was the predominant mineral followed by zinc and then iron. The amino acid profile was in accordance with the recommended pattern of FAO/WHO except for...

INTRODUCTION Genomic base composition ranges from less than 25% AT to more than 85% AT in prokaryotes. Since only a small fraction of prokaryotic genomes is not protein coding even a minor change in genomic base composition will induce profound protein changes. We examined how amino acid and codon frequencies were distributed in over 2000 microbial genomes and how these distributions were affec...
