Molecular Models

45.2K
Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

Molecular Shapes

63.2K
Molecules have characteristic shapes that are crucial for their function. The arrangement of various electron groups around the central atom dictates their molecular geometry. Electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between the electron pairs by maximizing the distance between them. The valence electrons form either bonding pairs, located primarily between bonded atoms, or lone pairs.

The Fluid Mosaic Model

183.7K
The fluid mosaic model was first proposed as a visual representation of research observations. The model comprises the composition and dynamics of membranes and serves as a foundation for future membrane-related studies. The model depicts the structure of the plasma membrane with a variety of components, which include phospholipids, proteins, and carbohydrates. These integral molecules are loosely bound, defining the cell’s border and providing fluidity for optimal function.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Computational Chemistry

Background:

  • Manipulating 3D molecular structures is crucial for understanding molecular functions.
  • Traditional mouse-and-keyboard controls for molecular graphics software are often difficult to learn.
  • Gesture-based and touch-based interactions are gaining popularity but their application in molecular graphics is underexplored.

Purpose of the Study:

  • To design and implement gesture-based and touch-based interaction methods for manipulating 3D molecular objects in PyMOL using a mobile device.
  • To evaluate the usability and performance of these new interaction methods.

Main Methods:

  • Developed gesture-based and touch-based interaction methods for PyMOL on mobile devices.
  • Utilized motion and touch sensors of mobile devices for control.
  • Implemented fundamental viewing controls (zooming, translation, rotation) and frequently used functions.

Main Results:

  • Pilot user study showed slightly reduced performance for viewing controls compared to mouse-and-keyboard.
  • Gesture and touch controls were found suitable for oral presentations.
  • The methods were considered equally suitable for educational scenarios like school classes.

Conclusions:

  • PyMOL mControl offers an alternative method for manipulating molecular graphics objects.
  • The new interaction methods provide novel user experiences.
  • The software is freely available for broader adoption and use.
