Chromatin Packaging

18.9K
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...

Phase Transitions

22.7K
Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

Phase Diagrams

A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

Area of Science:

  • Materials Science
  • Food Science
  • Sustainable Packaging

Background:

  • Global food waste, especially of perishables, is a major concern, often caused by supply chain temperature fluctuations.
  • Traditional non-degradable phase change material (PCM) packaging contributes to pollution.
  • There is a need for eco-friendly thermal regulation solutions in cold chain logistics.

Purpose of the Study:

  • To review the development and performance of bio-based PCM packaging systems.
  • To explore encapsulation strategies for improved thermal stability and leakage prevention.
  • To assess the potential of biodegradable PCM packaging for reducing food loss.

Main Methods:

  • Review of literature on bio-based PCM encapsulation techniques (e.g., spray drying, electrospinning, hydrogels).
  • Analysis of thermal characteristics and stability of various bio-based PCM systems.
  • Evaluation of challenges and advancements in biodegradable packaging, including the Indian context.

Main Results:

  • Bio-based PCMs integrated with natural polymers (PLA, starch, alginate, chitosan, cellulose) show potential for thermal regulation.
  • Encapsulation strategies significantly influence shell integrity, thermal stability, and PCM leakage.
  • Advancements focus on PCM stabilization and the shift towards biodegradable materials.

Conclusions:

  • Biodegradable PCM packaging is a viable strategy for extending perishable food shelf life and reducing waste.
  • This approach supports a circular economy in the food sector.
  • Scalability and cost-effectiveness remain key challenges, particularly in specific regional contexts like India.
