Grouped or individual amino acids from two diets were deleted to evaluate the effects of amino acids on larvae and adults of the Mediterranean fruit ßy, Ceratitis capitata (Wiedemann). Larvae died when fed with diets free of 10 exogenous essential amino acids (arginine, isoleucine, leucine, lysine, histidine,methionine, phenylalanine, threonine, tryptophan, and valine) or containing nine exogen...

In this series, we herein present our research on the physiology and usefulness of Branched-Chain Amino Acids. As often presented in the preceding issues of the journal, of the nine essential amino acids, valine, leucine and isoleucine, which have branched side chains, are called Branched-Chain Amino Acids (BCAAs). BCAAs play important roles, particularly during exercise and in the maintenance ...

Approximate analyses of mushroom protein (Pleurotus sp.) revealed that it contains 2.78% protein and 0.14% nonprotein nitrogen on a fresh-weight basis. A total of 17 amino acids, including all the essential amino acids, were qualitatively identified. Quantitative estimation of essential amino acids showed that, except for methionine and phenylalanine, all are in fairly high concentration. From ...

Essential amino acids such as methionine have been increasingly included into diets of lambs. However, few studies have determined the effects of methionine supplementation in the general performance and economic returns of lamb production. To address this question, 21weaned male Rahmani lambs were allotted to 3 dietary treatments: control diet (C), control diet plus 3.30 g of methionine/kg con...

The objective of the study was to determine the crude protein content and amino acid composition in bee-collected pollen from selected areas of Poland, South Korea and China. A total of 27 samples of pollen were examined after collection by bees. The dry substance, crude protein and amino acids were investigated in the study material. Amino acids were determined by ion exchange chromatography u...

Amino acid mixtures corresponding to either casein or egg yolk protein when fed to rabits ina low fat, cholesterol-free semipurified diet, produced the same degree of hypercholesterolemia as the proteins themselves. Amino acid mixtures corresponding to soy protein isolate or sunflower protein gave low plasma cholesterol levels, but not as low as those obtained with the intact proteins. Experime...

Background: Given the important role of amino acids in regulating many metabolic pathways of the body and considering the scarcity of markers for the diagnosis of inflammatory bowel disease (IBD) and its differentiation, we aimed to investigate the status of serum amino acids chromatography in children with IBD. Materials and Methods This case-control study was conducted among children with pri...

Background: Addition of amino acids to the culture medium is beneficial for embryonic development in many species. Objective: The objective of this study was to investigate the effects of amino acids on the in vitro maturation and embryonic development of the bovine oocyte. Materials and Methods: Bovine ovaries were collected from a local abattoir and brought into laboratory. Cumulus-oocyte com...

Protein utilization was determined by assay with low-protein diets limiting in one of nine essential amino acids. The diets contained 50 g protein/kg and the amino acid score of the protein was 0.50. Protein utilization was found to be related to the particular limiting essential amino acids present. The usefulness of Bender's (1965) standard amino acid requirement for the estimation of amino a...

Cu BA, T. Serum and Urine Amino Acid Analysis in Children with Biliary Atresia. Tohoku J. exp. Med., 1983, 139 (1), 61-66 Serum and urine amino acid levels were measured preoperatively and at varying time following successful hepatic portoenterostomy. All of the essential amino acids measured returned to normal levels during the late postoperative period over five years, whereas many of the non...
