Structural Isomerism

21.4K
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, SCN− can...

Structure-Activity Relationships and Drug Design

1.6K
Drug design is a dynamic field that involves discovering and developing new medications based on specific biological targets. This process heavily relies on structure-activity relationships (SAR) and quantitative structure-activity relationships (QSAR) to guide the design and optimization of efficient drugs.
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence...

¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)

1.6K
When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...

Structural Properties and Dimensions of Lumber01:21

Structural Properties and Dimensions of Lumber

359
Wood's structural properties derive from fibers aligned along the tree's length, contributing significantly to its mechanical strength. Wood exhibits up to twenty times greater tensile strength along these fibers compared to across them, and generally shows better performance under compression than tension. The length of fibers varies, with hardwoods having fibers around one twenty-fifth inch long and softwoods ranging from one-eighth to one-third inch.
The strength characteristics of...

Area of Science:

  • Structural biology
  • Bioinformatics
  • Scientific data visualization

Background:

  • The Protein Data Bank in Europe (PDBe) provides open access to experimentally determined macromolecular structures.
  • PDBe-Knowledge Base (PDBe-KB) enriches structural data with annotations.
  • Macromolecular entry pages are crucial for users accessing structural information.

Purpose of the Study:

  • To redesign the PDBe entry pages to improve usability and accessibility of macromolecular structure data.
  • To enhance the integration of 3D visualization, annotations, and user-uploaded data.
  • To support fundamental and applied research, as well as education in structural biology.

Main Methods:

  • Organizing content into logical views for improved navigation.
  • Integrating central 3D visualization tools.
  • Implementing AI-driven residue-level annotations via literature text mining.
  • Refactoring APIs for streamlined annotation access.
  • Enabling users to upload and visualize their own residue-level features.

Main Results:

  • A redesigned PDBe entry page with enhanced usability and logical content organization.
  • Integrated 3D visualization and sequence feature exploration.
  • AI-driven residue-level annotations and standardized molecular scenes.
  • User-uploaded features can be visualized alongside PDBe-KB annotations.
  • Streamlined access to structural data and annotations through refactored APIs.

Conclusions:

  • The redesigned PDBe entry pages offer a more accessible, flexible, and scalable framework for interacting with structural data.
