Transformable H-bonds and conformation in compressed glucose.
نویسندگان
چکیده
In response to external stimuli the α-d-glucose molecule extensively transforms its H-bonding pattern and conformation. High-pressure reverses the linear compressibility and changes the hierarchy of intermolecular interactions in crystalline α-d-glucose. At 5.40(2) GPa it undergoes an isostructural phase transition rearranging the OH···O hydrogen bonds, promoting the role of CH···O contacts and eliminating voids in the structure. Such monotonic and abrupt transformations may be characteristic of sugars and polysaccharides.

MOLECULAR MODELING AND NMR STUDY OF HISTDINIE AND ITS ANALOGUES AS , PYRIDOXAL 5 '-PHOSPHATE DEPENDENT HISTIDINE DECARBOXYLASE INHIBITORS
Molecular modeling analysis of charge density and heat of fornation by PM3 method as well as C, H NMR and 2D-NMR measurements of histidine (substrate) and some of its derivatives as histidine decarboxylase inhibitors were performed. It was established that the atom, usually nitrogen, which forms internal aldimine with pyridoxal5 -phosphate (PLP), (coenzyme), has negative and almost equal ...
متن کاملDecachlorohexa-1,5-diene
The title compound, C(6)Cl(10), cystallizes in a nearly C2-symmetrical gauche conformation. Both trichloro-vinyl groups are nearly planar [Cl-C-C-Cl torsion angles = -178.47 (12) and -179.93 (11)°] and the lengths of their C-Cl bonds increase from the terminal trans and cis C-Cl bonds to the inter-nal bonds. The Cl-C-Cl bond angles of the terminal dichloro-methyl-ene units are compressed to 111...

Flexibility is a concept associated with variable needs of human beings.Today transformable structures are used to meet human changeable demands with different purposes and functions such as facades, roofs, sunshades, etc.A Flexible structure must be able to change physically and adapt to predetermined conditions.To provide flexibility and adaptability,transformable systems are required to poss...
متن کاملVideo Abstraction in H.264/AVC Compressed Domain
Video abstraction allows searching, browsing and evaluating videos only by accessing the useful contents. Most of the studies are using pixel domain, which requires the decoding process and needs more time and process consuming than compressed domain video abstraction. In this paper, we present a new video abstraction method in H.264/AVC compressed domain, AVAIF. The method is based on the norm...
