Nucleic Acids02:43

Nucleic Acids

50.2K
Nucleic acids are the most important macromolecules for the continuity of life. They carry the cell's genetic blueprint and carry instructions for its functioning.
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...

Nucleic Acid Structure

8.8K
The pentose sugar in DNA is deoxyribose, while in RNA the pentose sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and a hydrogen on the deoxyribose's second carbon. The phosphate residue attaches to the hydroxyl group of the 5′ carbon of one sugar and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, which forms  a 5′ to 3′ phosphodiester linkage.

Structure of Lipids03:38

Structure of Lipids

98.7K
Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic...

Area of Science:

  • Biotechnology
  • Materials Science
  • Computational Chemistry

Background:

  • Lipid nanoparticles (LNPs) are crucial nonviral nucleic acid delivery systems.
  • Current LNP data is fragmented and lacks standardization, hindering systematic analysis.
  • A centralized repository, akin to the Protein Data Bank, is needed for LNPs.

Purpose of the Study:

  • To develop an integrated database and web tool for consolidating LNP structural and functional data.
  • To standardize LNP featurization and enable molecular dynamics simulations.
  • To facilitate data-driven design and improve LNP delivery performance prediction.

Main Methods:

  • Developed the Lipid Nanoparticle Database (LNPDB) consolidating data for 19,528 LNPs.
  • Standardized LNP featurization by encoding lipid composition, methods, and results.
  • Generated CHARMM force field files for lipids to support molecular dynamics simulations.

Main Results:

  • LNPDB provides a unified platform for LNP data analysis.
  • Applications demonstrated improved deep learning models for predicting LNP delivery.
  • Simulations identified bilayer stability and packing parameters correlating with delivery performance.

Conclusions:

  • LNPDB offers a digital framework for LNP modeling and data-driven design.
  • Standardized data and simulation capabilities will accelerate LNP development.
  • The database supports continued contributions for future growth and discovery.
