acids proline and hydroxyproline also react with ninhydrin, but they give a yellow colored complex instead of a purple one.
Las evidencias espectroscopicas muestran que el iminoester 3 realmente se encuentra en su forma enolica debido a que el hidrogeno del grupo OH forma un puente de hidrogeno con el N del grupo imino
, formando un intermediario de seis miembros termodinamicamente mas estable a su tautomero cetonico (Figura 3).
The determination of hydroxyproline in tissue and protein samples containing small proportions of this imino
c]) adjacent to the carbonyl group -C=0 and imino
group -NH, respectively.
Gelatin with high imino
acids (proline and hydroxyproline) has relatively high gel strength (Cho et al.
analogues of thiazolidinones are less widespread, even the accurate possibility to infer an additional manage for chemical variety and hereby allow of examination of unconjugated regions of a thiazolidinone-based pharmacophore (Laurent et al.
Cumming and his team at Merck have now designed an additional imino
heterocycle scaffold and in parallel have worked to further optimize binding interactions in sub-sites adjacent to the catalytic dyad.
1558-82-3; N- (Phosphonomethyl) Imino
DiaeticAcid 98% min.
Reaction mechanisms of formaldehyde with endocyclic Imino
groups of nucleic acid bases.
These THQ compounds were prepared using a three-component cationic imino
Diels-Alder cycloaddition methodology and a catalytic reduction (Romero & Kouznetsov 2010) that provided the N-benzyl- or N-H-1,2,3,4-tetrahydroquinoline derivatives with high structural diversity.
Polyethylenimine (PEI) is a water soluble cationic polymer which contains amino and imino
groups in each polymer chain.
Formaldehyde also crosslinks DNA by reacting with the imino
groups of DNA bases (26).
