Photometric ninhydrin method for use in the chromatography of amino acids.

Journal of Biological Chemistry, 1948
For the investigations on the chromatographic separation of amino acids outlined in the preceding communication (1)) it was necessary to have available a suitable quantitative method for the determination of the concentration of amino acids in the ...

Exploring the interplay between kidney function and urinary metabolites in young adults: the African-PREDICT study

Amino Acids
The exposure to modifiable risk factors at young ages have been linked to premature fatal and non-fatal cardiovascular and kidney outcomes. The use of urinary metabolomics has shown strong predictability of kidney function and cardiovascular disease (CVD)

Distances and classification of amino acids for different protein secondary structures

, 2003
Window profiles of amino acids in protein sequences are taken as a description of the amino acid environment. The relative entropy or Kullback-Leibler distance derived from profiles is used as a measure of dissimilarity for comparison of amino acids and ...

In vitro and in vivo studies on exogenous polyamines and α-difluoromethylornithine to enhance bone formation and suppress osteoclast differentiation

Amino Acids
Exogenous polyamines, including putrescine (PUT), spermidine (SPD), and spermine (SPM), and the irreversible inhibitor of the rate-limiting enzyme ornithine decarboxylase (ODC) of polyamine biosynthesis, α-difluoromethylornithine (DFMO), are implicated ...

The Triplet Genetic Code had a Doublet Predecessor

, 2004
Information theoretic analysis of genetic languages indicates that the naturally occurring 20 amino acids and the triplet genetic code arose by duplication of 10 amino acids of class-II and a doublet genetic code having codons NNY and anticodons ...

Prediction of matrilineal specific patatin-like protein governing in-vivo maternal haploid induction in maize using support vector machine and di-peptide composition

Amino Acids
The mutant matrilineal (mtl) gene encoding patatin-like phospholipase activity is involved in in-vivo maternal haploid induction in maize. Doubling of chromosomes in haploids by colchicine treatment leads to complete fixation of inbreds in just one ...

Endogenous levels of reducing sugars, free amino acids and phenols during various stages of in vitro culture of cotton (Gossypium Spp.) [PDF]

, 2010
Somatic embryogenesis is widely preferred as the regeneration route for in vitro studies in cotton. However, the regeneration efficiency through this approach is low; a problem that is believed to be as a result of the biochemical properties of the ...

d-Amino acids differentially trigger an inflammatory environment in vitro

Amino Acids
Studies in vivo have demonstrated that the accumulation of d-amino acids (d-AAs) is associated with age-related diseases and increased immune activation. However, the underlying mechanism(s) of these observations are not well defined. The metabolism of d-

Sequence analysis reveals extensive polymorphism and evidence of deletions within the E2 glycoprotein gene of several strains of murine hepatitis virus. [PDF]

, 1989
Direct RNA sequence analysis of the E2 gene of wild-type MHV-4 and of neutralization resistant, neuroattenuated variants has identified a polymorphic region with respect to deletions.
