Laboratory Tests for the Assessment of Nutritional Status
TL;DR: The CRC Critical Reviews in Clinical Laboratory Sciences: Vol. 4, No. 3, No 3, pp 215-340 as discussed by the authors was the first publication of a comprehensive review of laboratory tests for the assessment of nutritional status.
Journal ArticleDOI
Affinity labeling of the allosteric activator site(s) of spinach leaf ADP-glucose pyrophosphorylase.
TL;DR: Comparison of this sequence with the deduced amino acid sequence of a rice endosperm cDNA clone indicates that the putative allosteric site of the 51-kDa subunit is close to the carboxyl-terminal of the subunit, suggesting that pyridoxal phosphate is covalently bound to theAllosteric activator site.

Vitamin b6 transport in the central nervous system: in vivo studies
TL;DR: Results were interpreted as showing that the entry of B6 from blood into CSF and presumably the extracellular space of brain and thence into brain cells involves one or more saturable transport and/or metabolic steps.

Transport and metabolism of vitamin B6 in rabbit brain and choroid plexus.
R Spector,L L Greenwald +1 more
TL;DR: Results show that the regulation of accumulation of nonphosphorylated B,; vitamers is one mechanism by which the intracellular vitamin B levels in brain and choroid plexus are homeostatically maintained.

Allosteric sites of the large subunit of the spinach leaf ADPglucose pyrophosphorylase.
Kathryn L. Ball,Jack Preiss +1 more
TL;DR: Comparison of the sequences of the labeled tryptic peptides with those of large and small subunits of the enzyme from other species indicate their positions in the primary structure of the spinach enzyme large subunit suggest that these lysyl residues are involved in activator binding.

Separation and determination of vitamin B6 group (pyridoxine, pyridoxal, pyridoxamine, pyridoxal phosphate and pyridoxamine phosphate). Separation by paper electrophoresis of riboflavin (riboflavin, FMN and FAD) and of nicotinamide (nicotinamide, DPN and TPN) groups.
TL;DR: The separation and determination of vitamin B 6 forms with paper electrophoresis and starch column electrophoreis and a separation of all the above compounds from one mixture has also been obtained.
