Sulphur amino acid requirement of young pigs

Zeitschrift für Tierphysiologie Tierernährung und Futtermittelkunde, 1983
ZusammenfassungDer Bedarf an S‐haltigen Aminosäuren beim jungen wachsenden Schwein Mit Hilfe eines Wachstumsversuches von 144 Schweinen in Einzelfütterung und in einem Gewichtsabschnitt von 12–35 kg wurde der Bedarf an S‐haltigen Aminosäuren festgestellt.Die Tiere waren in sechs Gruppen mit je 12 weiblichen und 12 männlichen kastrierten Tieren ...

Sulphur Amino Acids

2013
The conversion of methionine to organic sulphate involves the formation of homocysteine involving transmethylation followed by transsulphuration. Several inherited enzyme deficiencies within this pathway have been described. Those causing hypermethioninaemia may be confused with the many known secondary causes of increased methionine demanding ...

Requirement of the hen for sulphur‐containing amino acids

British Poultry Science, 1978
The sulphur amino acid requirements of White Leghorn-type laying hens were determined in two 52-week experiments using diets based on maize and soyabean meal providing from 5.0 to 6.5 g sulphur amino acids/kg, 12.35 MJ ME/kg and 8.6 to 8.8 g lysine/kg. There were six replicates of 15 individually-caged hens each per treatment. 2.

PHOTOCHEMISTRY OF SULPHUR CONTAINING AMINO ACIDS AND PEPTTDES

Photochemistry and Photobiology, 1962
SummaryThe action of ultraviolet light (wavelength 2537Å) on cysteine, cystine, methionine, reduced and oxidized glutathione, and reduced insulin has been studied. Special attention is focussed on the influence of pH and of oxygen tension upon all reactions. On irradiation disulphides in acid medium, reductive cleavage of S‐S bonds dominates.

Amino-Acids of Red Sulphur Bacteria

Nature, 1959
THE growth of autotropic unicellular organisms in purely inorganic medium is of great interest in biological studies. The production of amino-acids by such organisms is intimately connected with this growth. In the case of unicellular green algae, the production of amino-acids have been investigated by Fowden1, Pearsall and Fogg2 and Eny3.

The Sulphur-Containing Amino Acids in Jaundice

Nature, 1944
WE have read with interest the letter from Peters et al. on "The Sulphur-containing Amino Acids in Jaundice"1. The authors would appear to have misunderstood the statements made in our previous note2 concerning the value of methionine treatment. We said only "that results would appear to show that the clinical course is influenced beneficially and the ...

Sulphur-containing Amino-Acids in the Rumen Bacteria of Sheep

Nature, 1949
As part of the investigations proceeding in this laboratory on the physiology and nutrition of sheep, the cyst(e)ine (cystine plus cysteine, calculated as cystine) and methionine contents of two large samples of mixed rumen bacteria were determined. The samples Were obtained from slaughterhouse rumens selected to represent sheep from ‘dry' and ‘green ...

Sulphur-amino acid metabolism in Aphis fabae

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1974
Abstract 1. 1. The trans-sulphuration of cysteine-35S to methionine-35S by Aphis fabae is shown to occur only when methionine is absent from the diet. 2. 2. Methionine is not metabolized to cysteine by the aphid. 3. 3. The inclusion of 0·01% chlortetracycline-HCl in a methionine-deficient diet incorporating cysteine-35S does not ...

Two new sulphur-containing amino acids in man

Biological Mass Spectrometry, 1981
Two unusual sulphur-containing amino acids have been isolated from urine of a baby who died with major physical malformations and failure of growth and development. Sensitive mass spectrometric methods were used to identify the nanomole quantities of the compounds available as S-(2-carboxypropyl)-cysteine and S-(2-carboxypropyl)-cysteamine.

Availability of sulphur amino‐acids in protein foods. I.—Total sulphur amino‐acid content in relation to sulphur and nitrogen balance studies with the rat

Journal of the Science of Food and Agriculture, 1964
AbstractFor a series of seven fish, meat and whale meals, there was no correlation between their sulphur content (expressed per 16 g. of N) and their net protein utilisation for rats although the quality of the protein was limited by the sulphur‐containing amino‐acids.
