Toxicity of Margarine on liver Enzymes (Aspartate amino transferas and Alanine amino transferase) in Rats
Background: Margarine contain trans fatty acids as major sources of dietary free radicals, and oxidative stress. Effect of oral administration of margarine on hepatic enzyme was investigated in Wistar rats. Methods: Thirty six (36) adult Wistar rats were uniformly divided into three groups of control , margarine 15% and 20%, twelve rats in each groups (6males & 6 females). Margarine was add...
متن کاملAvailability of amino acids for 10- to 20-kilogram pigs: lysine and threonine in soybean meal.
The availabilities of lysine and threonine in soybean meal for 10- to 20-kg pigs were determined in two experiments using slope-ratio methodology. In the first experiment, a basal diet formulated to contain 6 g of lysine/kg, but adequate in all other amino acids, was supplemented with 1, 2, or 3 g of lysine/kg from either soybean meal or L-lysine-HCl. Each of the seven diets was available on an...
متن کاملOptimum ratio to lysine of threonine, tryptophan, and sulfur amino acids for finishing swine.
Forty-eight crossbred (PIC line 26 x Camborough 15) pigs were used in two finishing trials to compare the ideal ratios of threonine (Thr), tryptophan (Trp), and sulfur amino acids (SAA) to lysine (Lys) determined for young pigs to a proposed ratio of these amino acids for finishing pigs. Trial 1 involved 20 barrows and 20 gilts that were self-fed in sex groups of two. Trial 2 was a Latin square...
متن کاملTheoretical Thermodynamic Study of Solvent Effects on Serine and Threonine Amino Acids at Different Temperatures
The thermodynamic functions such as enthalpy (H), Gibbs free energy (G) and entropy (S) of Serineand Threonine amino acids were theoretically studied at different condition (solvents andtemperatures) by using Gussian o3, software. First, the structural optimization of isolated Serine andThreonine were done in the gas phase by using the Hartree-Fock (HF) level of theory with 3-21G, 6-31G and 6-3...
متن کاملPhotosynthetic formation of the aspartate family of amino acids in isolated chloroplasts.
The metabolism of (14)C-labeled aspartic acid, diaminopimelic acid, malic acid and threonine by isolated pea (Pisum sativum L.) chloroplasts was examined. Light enhanced the incorporation of [(14)C] aspartic acid into soluble homoserine, isoleucine, lysine, methionine and threonine and protein-bound aspartic acid plus asparagine, isoleucine, lysine, and threonine. Lysine (2 millimolar) inhibite...
