The Essential Amino Acid Requirements of Man
The experiments of W. C. Rose16 brought to a successful conclusion the work of Osborne and Mendel,12 and that of Willcock and Hopkins; the matter of the protein requirements in nutrition is fundamentally a question of the need for each of the indispensable amino acids (Sherman"9). While the present crisis has intensified the need for evaluating the approximate human requirements for these essen...
متن کاملAmino acid requirements of broiler breeders at peak production for egg mass, body weight, and fertility.
Two trials were conducted to determine the amino acid and protein requirements of broiler breeders at peak production. In trial 1, 32-wk-old Cobb 500 broiler breeders with similar BW were selected to determine the digestible amino acid requirement for daily product output (g of egg mass + g of BW gain/b/d) and feed conversion (g of feed/g of product) for Met, Phe, Arg, Ile, Lys, and CP in a 42-...
متن کاملRemoval of Cysteine (an Aliphatic Amino Acid) by Natural Clinoptilolite
Amino acids have been extensively used in several processes of the pharmaceutical and food industries. Treatments for the recovery and reuse of the wastewaters generated from these processes are few and little known. This work aims at studying the influence of different variables on the sorption of L-cysteine, contained in aqueous solutions, on clinoptilolite mineral. L-Cysteine (Cys) was s...
متن کاملPostprandial body protein synthesis and amino acid catabolism measured with leucine and phenylalanine-tyrosine tracers.
Whether phenylalanine-tyrosine (Phe-Tyr) tracers yield estimates of postprandial protein synthesis comparable to those of the widely used leucine (Leu) tracer is unclear. We measured Leu oxidation (Ox), Phe hydroxylation (Hy), and their disposal into whole body protein synthesis before and after the administration of a mixed meal (62 kJ/kg body wt, 22% of energy as protein), over 4 h in healthy...
متن کاملAmino acid requirements and amino acid supply in the sheep.
The special features of nitrogen metabolism in ruminants, which stem from the extensive breakdown and synthesis of dietary protein in the rumen (see Hungate, 1966), imply the absence of a specific dietary requirement for essential amino acids. Nevertheless, there is considerable theoretical and practical interest in defining the amino acid requirements of ruminant tissues in animals of known nu...
