Performance of 2-Amino Tetraphenyl Porphyrin as Stationary Phase in RP-HPLC of Amino Acids
The search for new stationary phases has been one of the predominant concerns in high performance liquid chromatography (HPLC) in order to achieve better resolutions, longer column lives, and reduce the time of analysis. A chromatographic packing for separation of underivatized amino acids (AAs) were prepared by dynamically coating 2-amino tetraphenyl prophyrin (atpp) on a C-18 reversed-pha...
متن کاملAmino Acids in Ruminants
L-Lysine was microencapsulated by the spray-dry met.hod for improvement of the balance of alllino acids in ruminants. The rumen-bypm;s lllicrocCljJsulc was jJrqmn~d using zein or shellac as an outer coat.ing agcnt [or protection against microbial degradation in the rumen. L-Lysine was generated with a .yield of ,')0% in casp of zein microcapsules and :3:3% in shellac microcapsules and a mean pa...
متن کاملAmino Acids in Aqueous Solution
In the previous chapter, the focus was mainly on the behavior of ions in solution. The effect of concentration, solvent, as well as pH have been investigated; furthermore, alkali metal ions as well as transition metal ions have been studied. In this chapter, the investigation will be extended from ions to molecules, more specifically toward the behavior of amino acids in solution. Amino acids a...
متن کاملcx-AMINO ACIDS IN CHILDREN
The determination of the total content of free a-amino acids in urine has become routine in paediatric practice in numerous diseases. Interest in aminoaciduria has greatly increased since it became known that many congenital metabolic disorders are accompanied by an increased excretion of free oc-amino acids in the urine (Paine, 1960; Woolf, 1961). The excretion of free a-amino-N is usually exp...
متن کاملAmino acids in retinitis pigmentosa.
A survey of fasting whole blood amino acids in 65 patients with various subtypes of retinitis pigmentosa performed. Eight X-linked recessive patients showed decreased taurine and aspartate. Nineteen autosomal recessive patients, and to lesser extent 10 autosomal dominant patients, showed reduced levels of whole blood threonine and histidine. Branched-chain amino acids and arginine were present ...
