Stereoisomers of hydroxyproline.
Hydroxy-L-proline was first isolated by Fischer in 1902 from a hydrolysate of gelatin (l).l The synthesis and determination of the structure were reported by Leuchs and coworkers (5--g), and, in 1919, the separation of the two racemic stereoisomers and the resolution of each racemate through mixtures of quinine with the corresponding N-phenylisocyanate derivatives were accomplished (5). In the ...
متن کاملContiguous hydroxyproline residues direct hydroxyproline arabinosylation in Nicotiana tabacum.
Hydroxyproline (Hyp) O-glycosylation characterizes the hydroxyproline-rich glycoprotein (HRGP) superfamily of the plant extracellular matrix. Hyp glycosylation occurs in two modes: Arabinosylation adds short oligoarabinosides (Hyp-arabinosides) while galactosylation leads to the addition of larger arabinogalactan polysaccharides (Hyp-polysaccharides). We hypothesize that sequence-dependent glyc...
متن کاملThe determination of hydroxyproline.
There has been a great need for a satisfactory method for the determination of hydroxyproline to facilitate the study of the composition of proteins. Lang (1) and Waldschmidt-Leitz and Akabori (2) developed a calorimetric estimation involving oxidation to pyrrole with sodium hypochlorite and color formation with isatin or p-dimethylaminobenzaldehyde. However, oxidation was said to be incomplete...
متن کاملType-Itemized Enumeration of RS-Stereoisomers of Octahedral Complexes
Stereoisograms of octahedral complexes are classified into five types (type I--typeV) under the action of the corresponding RS-stereoisomeric group. Their enumeration is accomplished in a type-itemized fashion, where Fujita's proligand method developed originally for combinatorial enumeration under point groups (S. Fujita, Theor. Chem. Acc., 113, 73--79 (2005)) is extended to meet the requireme...
متن کاملDetermination of hydroxyproline in liver.
THE DETERMINATION of hydroxyproline in parenchymous tissues such as liver presents special problems not encountered in collagenons tissues. This is true because liver contains only small quantities of this imino acid (1), and furthermore, the existing quantitative tests are nonspecific. Thus, if one were to use the usually acceptable Neuman and Logan procedure (2), a separate determination for ...
