Dietary glycine needs of broiler chicks.
Dietary Gly might become a limiting factor in all-vegetable diets fed to broiler chicks when low CP is formulated in combination with marginal levels of dietary Thr and Ser. A study was conducted to evaluate dietary Gly needs of broiler chicks. Day-old Ross 508 male chicks were placed in 32 floor pens (15 chicks/pen). Chicks were fed a common prestarter diet from 0 to 7 d of age and then fed a ...
متن کاملThe formation of glycine and serine; the influence of the administration of glycine, DL-serine and other compounds on levels of tissue glycine and serine.
The rates of conversion of glycine into serine and serine into glycine have been determined by administration of isotopically labelled glycine and serine (Arnstein & Neuberger, 1953; Elwyn & Sprinson, 1954; Arnstein & Keglevi6, 1956; Arnstein & Stankovid, 1956). The present investigation, which is concerned with the net synthesis of glycine from serine, and of serine from glycine, was carried o...
متن کاملEvidence for the involvement of serine transhydroxymethylase in serine and glycine interconversions in Salmonella typhimurium.
Salmonella typhimurium can normally use glycine as a serine source to support the growth of serine auxotrophs. This reaction was presumed to occur by the reversible activity of the enzyme, serine transhydroxymethylase (E. C. 2. 1. 2. 1; L-serine: tetrahydrofolic-5, 10 transhydroxymethylase), which is responsible for glycine biosynthesis. However, this enzyme had not been demonstrated to be sole...
متن کاملThe conversion of glycine into serine in the intact rat.
We have investigated this pathway by degrading liver serine isolated after the administration of glycine labeled with Cl4 in the methyl position. According to the proposed scheme the OLand p-carbon atoms of serine are both derived from the methyl carbon of glycine and should contain the isotope. Four fasted rats weighing a total of 427 gm. were given 5 rniM of glycine by stomach tube per 100 gm...
متن کاملCertain interrelationships in the metabolism of glycine and serine.
The utilization of L-serine-2,3-deuterio, 3-C4, N16 and glycine-2-C4, N15 for the biosynthesis of purines, thymine, and choline in the rat was described briefly in preliminary publications from this laboratory (1, 2). In the synthesis of the methyl groups of choline from the p-C14DaOH group of isotopically labeled serine it was later found (3) that t,he C14:D ratio was unaltered, indicating tha...
