A mutation in amino acid permease AAP6 reduces the amino acid content of the Arabidopsis sieve elements but leaves aphid herbivores unaffected [PDF]

open access: yes, 2010
The aim of this study was to investigate the role of the amino acid permease gene AAP6 in regulating phloem amino acid composition and then to determine the effects of this altered diet on aphid performance.

A Modified GC-MS Analytical Procedure for Separation and Detection of Multiple Classes of Carbohydrates

open access: yesMolecules, 2018
A modified GC-MS analytical procedure based on trimethylsilyl-dithioacetal (TMSD) derivatization has been established for a simultaneous determination of thirteen carbohydrates. Different from previous approaches, the current GC-MS method was featured by

Versatile Approaches to Sugar Amino Acid Building Blocks as Precursors of Glycopeptides

open access: yesCHIMIA, 2007
The synthesis of monosaccharide units functionalised with different amino acids is described herein. Sugar amino acid templates linked at position 6 of the sugar were prepared by various nucleophilic substitutions introducing a spacer of ...

The sweet life: diet sugar concentration influences paracellular glucose absorption [PDF]

open access: yes, 2008
Small birds and bats face strong selection pressure to digest food rapidly in order to reduce digesta mass carried during flight. One mechanism is rapid absorption of a high proportion of glucose via the paracellular pathway (transfer between epithelial ...

Crystal Structure of Methyl 4-Acetamido-4-cyano-4,6-dideoxy-2,3-O-isopropylidene-ß-D-allopyranoside

open access: yesMolecules, 2000
The detailed structure of methyl 4-acetamido-4-cyano-4,6-dideoxy-2,3-Oisopropylidene-ß-D-allopyranoside was established by X-ray analysis confirming allo configuration at C-4 and suggesting a 4C1 conformation of the pyranose ring.

Root phloem-specific expression of the plasma membrane amino acid proton co-transporter AAP3 [PDF]

open access: yes, 2004
Amino acids are regarded as the nitrogen ‘currency’ of plants. Amino acids can be taken up from the soil directly or synthesized from inorganic nitrogen, and then circulated in the plant via phloem and xylem.
