Molecular Models

Molecular Models

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

Molecular Shapes

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.
Two regions of electron density in a diatomic...

Gibbs Free Energy

Gibbs Free Energy

One of the challenges of using the second law of thermodynamics to determine if a process is spontaneous is that it requires measurements of the entropy change for the system and the entropy change for the surroundings. An alternative approach involving a new thermodynamic property defined in terms of system properties only was introduced in the late nineteenth century by American mathematician Josiah Willard Gibbs. This new property is called the Gibbs free energy (G) (or simply the free...

Negative Regulator Molecules

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Positive Regulator Molecules

Positive Regulator Molecules

To consistently produce healthy cells, the cell cycle—the process that generates daughter cells—must be precisely regulated.

Area of Science:

Cheminformatics
Computational Chemistry
Web Development

Background:

Molecule editors are essential for cheminformatics and molecular processing.
The JME applet has been a popular web-based tool for molecular structure input.
Java applets face increasing implementation challenges due to maintenance, support, and security concerns.

Purpose of the Study:

To update the JME editor for modern web environments.
To port the JME editor to JavaScript.
To create a web-based molecule editor that is easy to use and integrate.

Main Methods:

Translated existing JME Java code to JavaScript using the Google Web Toolkit compiler.
Developed a custom library to emulate Java GUI features in JavaScript.
Enhanced the editor with new functionalities like a substituent menu, copy/paste, drag and drop, and undo/redo.

Main Results:

The JSME editor was successfully developed and is compatible with JME.
The editor supports molecule editing on both desktop and touch devices (iOS and Android).
Additional features include a substituent menu, copy/paste, drag and drop, and undo/redo capabilities.

Conclusions:

JSME is a compact, user-friendly, and easily embeddable JavaScript molecule editor.
It is released under a BSD license and maintains compatibility with JME's user interface and API.
JSME offers a modern alternative to Java applets for web-based molecular structure editing.
