Phase Diagrams02:39

Phase Diagrams

49.0K
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...

Metallic Solids02:37

Metallic Solids

20.5K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Peptide Bonds02:43

Peptide Bonds

82.4K
A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...

Structures of Solids02:22

Structures of Solids

17.5K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

Phase Transitions02:31

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 Transitions: Sublimation and Deposition02:33

Phase Transitions: Sublimation and Deposition

19.8K
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

Area of Science:

  • Organic Chemistry
  • Biochemistry
  • Chemical Engineering

Background:

  • Fmoc-based solid-phase peptide synthesis (SPPS) is a cornerstone of peptide production.
  • Optimizing SPPS efficiency, particularly for complex peptides, remains an active area of research.

Main Methods:

  • Application of ultrasonic irradiation during Fmoc-based SPPS.
  • Synthesis of various biologically active peptides, including those with challenging sequences (up to 44-mer).

Main Results:

  • Ultrasonication significantly reduced material and reaction time in SPPS.
  • The US-SPPS method did not increase major side reactions.
  • Improved synthesis yields for peptides with difficult sequences were observed.

Conclusions:

  • US-SPPS is a highly efficient peptide synthesis strategy.
  • Ultrasonic irradiation offers a viable method to enhance SPPS, particularly for complex peptide targets.
  • This approach streamlines peptide production, reducing resource consumption.
