All ortho–para directors, excluding halogens, are activating groups. These groups donate electrons to the ring, making the ring carbons electron-rich. Consequently, the reactivity of the aromatic ring towards electrophilic substitution increases. For instance, the nitration of anisole is about 10,000 times faster than the nitration of benzene. The electron-donating effect of the methoxy group in anisole activates the ortho and para positions on the ring and stabilizes the corresponding...

Balancing Redox Equations

62.5K
Electrochemistry is the science involved in the interconversion of electrical and chemical reactions. Such reactions are called reduction-oxidation, or redox reactions. These important reactions are defined by changes in oxidation states for one or more reactant elements and include a subset of reactions involving the transfer of electrons between reactant species. Electrochemistry as a field has evolved to yield sufficient insights on the fundamental principles of redox chemistry and multiple...

Chromatin Packaging

Each human somatic cell contains 6 billion base pairs of DNA. Each base pair is 0.34 nm long, meaning each diploid cell contains a staggering 2 meters of DNA. This long DNA strand is packed inside a nucleus measuring only 10-20 microns in diameter with the help of specialized DNA-binding proteins called histones. Together they form a compact DNA-protein complex called chromatin. The chromatin is further compacted into higher-order structures. The highest level of compaction is achieved during...

Each human somatic cell contains 6 billion base-pairs of DNA. Each base-pair is 0.34 nm long, which means that each diploid cell contains a staggering 2 meters of DNA. How is such a long DNA strand packed inside a nucleus measuring only 10 - 20 microns in diameter? 
The chromatin
In combination with specialized DNA binding protein called Histones, the DNA double helix forms a compact DNA: protein complex called chromatin. The chromatin itself is further compacted into higher-order...

Area of Science:

  • Systems Biology
  • Computational Biology
  • Bioinformatics

Background:

  • Constraint-based modeling is crucial for analyzing large-scale biological networks.
  • Steady-state flux models are typically analyzed using optimization techniques like flux balance analysis (FBA).

Purpose of the Study:

  • To introduce the Flux Balance Constraints (FBC) Package, an extension of SBML Level 3.
  • To provide a standardized format for encoding, exchanging, and annotating constraint-based models.
  • To enhance the FBC Package with support for gene-protein associations in version two.

Main Methods:

  • The FBC Package extends the Systems Biology Markup Language (SBML) Level 3.
  • It incorporates support for objective functions, flux bounds, and reaction balancing.
  • Version two specifically adds elements for gene-protein associations.

Main Results:

  • The FBC Package offers a standardized method for representing constraint-based models.
  • It facilitates reaction balancing and model component annotation.
  • Version two expands capabilities to include gene-protein association encoding.

Conclusions:

  • The FBC Package provides a robust and standardized format for constraint-based modeling.
  • It promotes interoperability and facilitates cross-community development of biological network models.
  • The inclusion of gene-protein associations in version two further enhances its utility.
