Radical Chain-Growth Polymerization: Chain Branching01:17

Radical Chain-Growth Polymerization: Chain Branching

2.6K
The skeletal structure of polymers synthesized via radical polymerization is always branched. For example, the polymerization of ethylene by radical polymerization results in a low-density grade of polyethylene with a heavily branched skeletal structure. Here, the radical site abstracts hydrogen from the growing chain, and the radical site shifts from the end (a primary carbon center) to anywhere within the growing chain (a secondary carbon center). Consequently, the part of the chain from the...

Polymer Classification: Architecture

4.1K
Polymers are classified as linear or branched on the basis of their chain architecture. The polymer chains in linear polymers have a long chain-like structure with minimal to no branching at all. Even if a polymer features large substituent groups on the monomer, which appear as branches to the skeleton, it is not considered a branched polymer. A branched polymer contains secondary polymer chains that arise from the main polymer chain. The branching occurs when the polymer growth shifts from...

Meristems and Plant Growth

50.5K
Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.

Enlargement of the Plasma Membrane

2.6K
Cell division and enlargement are processes that require precise control. The control ensures that cell division cannot proceed unless the cell has grown to a specific size. A spherical, dividing cell requires an approximately 1.6X increase in its surface area to double its volume. The secretory pathway also has a significant role in cell membrane enlargement. Secretory vesicles that bud off from the Golgi apparatus and later fuse with the plasma membrane during exocytosis are a major source of...

Primary and Secondary Growth in Roots and Shoots

61.5K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Basic Plant Anatomy: Roots, Stems, and Leaves

The primary organs of vascular plants are roots, stems, and leaves, but these structures can be highly variable, adapted for the specific needs and environment of different plant species.

Area of Science:

  • Biochemistry
  • Developmental Biology
  • Physiology

Background:

  • Blood vessel formation, or angiogenesis, is crucial for development and disease.
  • The precise molecular mechanisms governing vessel branching and expansion remain incompletely understood.

Purpose of the Study:

  • To investigate the role of oscillating protein signals in regulating blood vessel morphogenesis.
  • To elucidate the signaling pathways involved in controlling vascular network development.

Main Methods:

  • Utilized advanced imaging techniques to observe dynamic protein signaling in vivo.
  • Employed genetic manipulation to study the function of key signaling proteins in endothelial cells.

Main Results:

  • Demonstrated that oscillations in specific protein signals directly correlate with blood vessel branching events.
  • Identified critical thresholds and frequencies of protein oscillations that dictate vessel expansion.

Conclusions:

  • Oscillating protein signals are essential regulators of blood vessel branching and expansion.
  • Understanding these dynamic signaling patterns offers new avenues for targeting vascular diseases.
