Condensation dynamics of the L-Pro-L-Phe and L-Hyp-L-Phe binary mixtures in solution.
We employ the achiral liquid chromatography with diode array, evaporative light scattering and mass spectrometric detection (HPLC-DAD, HPLC-ELSD and LC-MS) to assess structural instability (understood as spontaneous oscillatory chiral conversion and spontaneous oscillatory condensation) of the two pairs of amino acids, L-proline-L-phenylalanine (L-Pro-L-Phe) and L-hydroxyproline-L-phenylalanine...
متن کاملl-Alanine hydrochloride monohydrate
Colorless crystals of l-alanine hydrochloride monohydrate, C(3)H(8)NO(2) (+)·Cl(-)·H(2)O, were obtained from a powder sample that had been left standing in a refrigerator for a few years. The structure displays several inter-molecular hydrogen bonds: the hydroxyl O atom is involved in a single hydrogen bond to the chloride anion, while the ammonium group forms one hydrogen bond to the chloride ...
متن کاملPathway of noradrenaline formation from DOPA.
Three compounds have each been postulated as the possible immediate precursor of noradrenaline (1) : p-hydroxyphenylethanolamine, dihydroxyphenylserine, and hydroxytyramine. Erspamer (2) found p-hydroxyphenylethanolamine in the salivary gland of the octopus; however, the compound has not been reported to be present in mammalian tissues, nor has it been shown that it can be converted to noradren...
متن کاملLactobacillus plantarum MiLAB 393 produces the antifungal cyclic dipeptides cyclo(L-Phe-L-Pro) and cyclo(L-Phe-trans-4-OH-L-Pro) and 3-phenyllactic acid.
We have isolated a Lactobacillus plantarum strain (MiLAB 393) from grass silage that produces broad-spectrum antifungal compounds, active against food- and feed-borne filamentous fungi and yeasts in a dual-culture agar plate assay. Fusarium sporotrichioides and Aspergillus fumigatus were the most sensitive among the molds, and Kluyveromyces marxianus was the most sensitive yeast species. No inh...
متن کاملInfinite pleated -sheet formed by the -hairpin Boc- -Phe- -Phe-D-Pro-Gly- -Phe- -Phe-OMe
A -hairpin conformation and extended -pleated sheet assembly have been characterized by single crystal x-ray diffraction for the synthetic peptide t-butoxycarbonyl— -Phe-Phe-D-Pro-GlyPhe-Phe-methyl ester [ -Phe: (S)3 homophenylalanine]. The centrally located D-Pro-Gly segment nucleates a chain reversal in a type II -turn conformation. Two intramolecular cross-strand hydrogen bonds stabilize the...
