Molecular Models

37.7K
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.

Newman Projections

16.2K
Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as...

Structural Isomerism

Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly,...

Fischer Projections02:18

Fischer Projections

12.9K
Learning to draw Fischer projections of molecules and understanding their relevance plays a crucial role in the visual depiction of organic molecules. A Fischer projection is a two-dimensional projection on a planar surface to simplify the three-dimensional wedge–dash representation of molecules. This is especially helpful in the case of molecules with multiple chiral centers that can be difficult to draw. Here, all the bonds of interest are represented as horizontal or vertical lines.

Molecules with Multiple Chiral Centers02:25

Molecules with Multiple Chiral Centers

11.1K
Molecules that possess multiple chiral centers can afford a large number of stereoisomers. For instance, while some molecules like 2-butanol have one chiral center, defined as a tetrahedral carbon atom with four different substituents attached, several molecules like butane-2,3-diol have multiple chiral centers. A simple formula to predict the number of stereoisomers possible for a molecule with n chiral centers is 2n. However, there can be a lower number where some of the stereoisomers are...

Stereoisomerism of Cyclic Compounds02:33

Stereoisomerism of Cyclic Compounds

8.6K
In this lesson, we delve into the role of ring conformation and its stability, which determines the spatial arrangement and, consequently, the molecular symmetry and stereoisomerism of cyclic compounds. 1,2-Dimethylcyclohexane is used as a case study to evaluate the possible number of stereoisomers. Here, given the multiple (n = 2) chiral centers, there are 2n = 4 possible configurations that lack a plane of symmetry, as the ring skeleton exists in a non-planar chair conformation. In addition,...

Area of Science:

  • Biochemistry and Cheminformatics
  • Natural Product Discovery
  • Computational Chemistry

Background:

  • Natural products are vital for medicine, materials, and agriculture, but their biosynthetic pathways are often unknown, limiting their use.
  • Existing molecular representation systems focus on connectivity, not spatial arrangements, hindering their application in pathway elucidation.
  • Drug discovery utilizes molecular representation systems, but these are rarely integrated with biosynthetic pathway studies.

Purpose of the Study:

  • To develop and implement a common-reference-frame molecular representation system for natural product analysis.
  • To bridge the gap between molecular structure representation and biosynthetic pathway elucidation.
  • To explore the system's utility in understanding natural product structural diversity and biosynthesis.

Main Methods:

  • Developed a common-reference-frame molecular representation system based on skeleton-based approaches.
  • Applied the system to analyze triterpenoid structures as a case study.
  • Integrated phylogenetic distribution data with molecular representations.

Main Results:

  • The system effectively identifies regions of high and low structural variability at the atomic and bond level.
  • Hierarchical clustering based on the system correlates closely with underlying biosynthetic pathways.
  • The system elucidates distinct sources of structural variability, linking them to enzyme families and phylogenetic distribution.

Conclusions:

  • Common-reference-frame molecular representation systems offer a powerful tool for large-scale natural product pathway elucidation.
  • This approach enhances the understanding of structural diversity and its biosynthetic origins.
  • The system has significant potential to accelerate the discovery and application of natural products.
