Summary
This study explores conformational changes in nigeran (mycodextran) oligosaccharides. Using Enforced Geometry Optimization (EGO), researchers simulated structural transitions within the glucopyranose rings of this fungal polysaccharide.
Area of Science:
- Biochemistry
- Polymer Science
- Mycology
Background:
- Mycodextran, also known as nigeran, is a polysaccharide.
- It is composed of α-d-glucopyranose units linked by (1→3) and (1→4) glycosidic bonds.
- Nigeran is produced by fungi such as Aspergillus niger and Penicillium crustosum.
Purpose of the Study:
- To investigate potential enforced conformational transitions in the glucopyranose rings of nigeran oligosaccharides.
- To simulate and analyze structural changes within nigeran chains.
Main Methods:
- The study employed the Enforced Geometry Optimization (EGO) method.
- EGO was used to simulate conformational changes in the polysaccharide structure.
Main Results:
- The research examined specific enforced conformational transitions within the nigeran oligosaccharide chains.
- Simulation results provide insights into the structural dynamics of nigeran.
Conclusions:
- The Enforced Geometry Optimization method is effective for studying nigeran conformational changes.
- Understanding these transitions is crucial for characterizing nigeran's structure and properties.

1.2K
At room temperature, the chair conformer of cyclohexane undergoes rapid ring flipping between two equivalent chair conformers at a rate of approximately 105 times per second. These two chair conformers are in equilibrium. The rapid ring flipping results in the interconversion of the axial proton to an equatorial proton and an equatorial to the axial proton. Such interconversions are too rapid and cannot be detected on the NMR timescale. Hence, the NMR spectrometer cannot distinguish between the...

1.6K
The axial and equatorial protons in cyclohexane can be distinguished by performing a variable-temperature NMR experiment. In this process, except for one proton, the remaining eleven protons are replaced by deuterium. The deuterium substitution avoids the possible peak splitting caused by the spin-spin coupling between the adjacent protons. The remaining proton flips between the axial and equatorial positions.

Cyclohexane does not exist in a planar form due to the high angle and torsional strain it would experience in the planar structure. Instead, it adopts non-planar chair and boat conformations.
The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal...

3.2K
The living membranes are flexible due to their fluid mosaic nature; however, their bending into different shapes is an active process regulated by specific lipids and proteins. The membrane bending can be transient as seen in vesicles or stable for a long time as in microvilli. Cells regulate the size, location, and duration of the membrane curvature.
Membrane bending can happen due to intrinsic changes in lipid composition or extrinsic association with different proteins. The proteins involved...

Cell membranes are composed of phospholipids, proteins, and carbohydrates loosely attached to one another through chemical interactions. Molecules are generally able to move about in the plane of the membrane, giving the membrane its flexible nature called fluidity. Two other features of the membrane contribute to membrane fluidity: the chemical structure of the phospholipids and the presence of cholesterol in the membrane.

Membrane fluidity is explained by the fluid mosaic model of the cell membrane, which describes the plasma membrane structure as a mosaic of components—including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character.
Mosaic nature of the membrane
The mosaic characteristic of the membrane helps the plasma membrane remain fluid. The integral proteins and lipids exist as separate but loosely-attached molecules in the membrane. The membrane is...
