Background: Rice seed proteins are lacking essential amino acids (EAAs). Genetic engineering off ers a fast and sustainable method to solve this problem as it allows the specifi c expression of heterologous EAA-rich proteins. The use of selectable marker gene is essential for generation of transgenic crops, but might also lead to potential environmental and food safety problems...

Protein and energy are the two major components of feed that influence performance of the growing and fattening lambs. Provision of the quality of protein in the lamb’s diet does not only improve the animal performance but also ensures profitable animal production. Different vegetable protein sources are used to formulate the rations for growing and fattening lambs. These protein sources differ...

A procedure is described for the direct determination of methyl derivatives of basic amino acids in total acid hydrolyzates of proteins by the use of a Beckman amino acid analyzer operated in the high sensitivity mode with automatic integration. The conditions described permit the separation of ornithine, lysine, 5-hydroxylysine, N’-monomethyllysine, N”-dimethyllysine, histidine, N’-methylhisti...

We have studied the ability of branched chain ammo-acid enriched total parenteral nutrition solutions to improve nutritional status without stimulating tumor growth. Protein kinetics, nitrogen balance, tumor kinetics, fractional synthetic rates of individual tissues, and albumin synthesis were compared in male Sprague-Dawley rats (125-145 g) that had either s.c. Yoshida sarcoma (n = 15) or sham...

An investigation into the concentrations of amino acids in the liver and heart of Cricetomys gambianus was carried out. The most abundant amino acid was Glu (12.9-13.0 g/100 g) and Leu was the most abundant essential amino acid (6.94-7.65 g/100 g). Whilst total amino acid content was 83.491.4 g/100 g crude protein, the total essential amino acid content was 38.6-42.2 g/100 g or 46.2-46.3% with ...

Rhododendron is one of the largest shrubs and is well known as a garden plant because of their evergreen leaves and various flower colors. The present study investigated the variation in amino acids in the differently colored flowers of Rhododendron schlippenbachii. Analysis of the Rhododendron flowers revealed 22 types of amino acids. The amino acid content varied greatly depending on the diff...

this paper considers the generation of some interpretable fuzzy rules for assigning an amino acid sequence into the appropriate protein superfamily. since the main objective of this classifier is the interpretability of rules, we have used the distribution of amino acids in the sequences of proteins as features. these features are the occurrence probabilities of six exchange groups in the seque...

three experiments were conducted to evaluate the nutritional value of bitter vetch. experiment 1 was conducted to determine the metabolisable energy content of bitter vetch. sixteen adult leghorn roosters were used. forty grams of bitter vetch were precision-fed individually to 12 roosters. in addition, 4 birds were not fed and served as a control treatment in the measurement of metabolic fecal...
