Studies on Free Amino Acids in the Tea

A Review on Recent Findings on Amino Acids Requirements in Poult-Studies

Amino acids (AA) are important in poultry nutrition not only for protein deposition, but also for other metabolic functions; such as improving immune and gut functions. Although, some table values are available on amino acids requirement, AA requirements may vary due to changes in dietary composition and breeding selection. Thus amino acids requirements have remained an ongoing research topic. ...

Studies on the free amino acids and related compounds in the tissues of the cat.

The present study has been undertaken to obtain information on the amino acids and related compounds of animal tissues by the chromatographic analysis of protein-free extracts on columns of sulfonated polystyrene resins (2). The nature and quantity of bound forms of amino acids have been investigated by analysis of the extracts before and after acid hydrolysis. The tissues of the cat were chose...

Influence of ingestion of single amino acids on the blood level of free amino acids.

Our studies of normal and abnormal subjects have demonstrated that the postabsorptive levels of the free amino acids of the plasma remain within rather narrow normal limits except in very extreme terminal conditions. This investigation was made to determine whether the levels of all of the amino acids in the plasma are maintained by the same mechanism and whether there are any cross-relationshi...

Studies on the unknown amino acids in normal human urine.

Studies on the crystalline lens. IX. Quantitative analysis of free amino acids and related compounds.

The concentration of all free amino acids and many related compounds in the lens of rabbits has been determined by ion exchange chromatography, and the concentration of the amino acids in the lens has been compared with those found in a previous study in aqueous and. vitreous humors. The concentration of every free amino acid in the lens was shoiun to be higher than in the aqueous of the poster...
