Reactivity of Enols01:18

Reactivity of Enols

4.0K
Enols are a class of compounds where a hydroxyl group is attached to a carbon–carbon double bond, which implies that it is a vinyl alcohol. A carbonyl compound with an α hydrogen undergoes keto–enol tautomerism and remains in equilibrium with its tautomer, the enol form. Usually, the keto tautomer is present in a higher concentration than the enol tautomer due to the higher bond energy of C=O compared to C=C. Moreover, the direction of the keto–enol equilibrium is...

Reactivity of Enolate Ions01:23

Reactivity of Enolate Ions

3.3K
Enolate ions are formed by the acid–base reaction of a carbonyl compound with a base. This leads to deprotonation of the α hydrogen atom, leading to a resonance-stabilized enolate ion where one of the contributing structures is an oxyanion, which imparts additional stability. Therefore, the proton on the α carbon is more acidic in nature than that of other sp3-hybridized C–H bonds but less acidic than those in O–H bonds where the negative charge in the conjugate...

Radical Reactivity: Overview01:11

Radical Reactivity: Overview

2.6K
Radicals, the highly reactive species, gain stability by undergoing three different reactions. The first reaction involves a radical-radical coupling, in which a radical combines with another radical, forming a spin‐paired molecule. The second reaction is between a radical and a spin‐paired molecule, generating a new radical and a new spin‐paired molecule. The third reaction is radical decomposition in a unimolecular reaction, forming a new radical and a spin‐paired...

Radical Reactivity: Nucleophilic Radicals01:16

Radical Reactivity: Nucleophilic Radicals

2.6K
Radicals adjacent to electron-donating groups are called nucleophilic radicals. These radicals readily react with electrophilic alkenes. The SOMO–LUMO interactions are the driving force for the reaction, where the high-energy SOMO of the electron-rich, nucleophilic radicals interacts with the low-energy LUMO of the electron-deficient, electrophilic alkenes. Such SOMO–LUMO interactions are the basis of reactive radical traps, affecting the selectivity in radical reactions. For...

Radical Reactivity: Intramolecular vs Intermolecular01:33

Radical Reactivity: Intramolecular vs Intermolecular

2.1K
Radical reactions can occur either intermolecularly or intramolecularly. In an intermolecular radical reaction, a nucleophilic radical adds to an electrophilic alkene or vice versa. In such reactions, the radical and generally the alkene, which is also called the radical trap, are two different molecules. Additionally, for such intermolecular reactions to occur, the radical trap must be active, present in an excess concentration, and the radical starting material must have a weak...

Area of Science:

  • Immunology
  • Endocrinology
  • Biochemistry

Background:

  • Hybrid insulin peptides (HIPs) are fusion peptides formed in pancreatic beta cells.
  • These peptides contain non-genomically encoded sequences, making them potential targets in type 1 diabetes (T1D).
  • HIPs are detected in human and murine islets and targeted by T cells in T1D models and patients.

Purpose of the Study:

  • To review the discovery and role of HIPs in T1D pathogenesis.
  • To discuss the function of HIP-reactive T cells in diabetes development.
  • To explore HIP generation mechanisms and mass spectrometry challenges for new HIP discovery.

Main Methods:

  • Review of original discovery and recent studies on HIPs.
  • Analysis of T cell responses to HIPs in mouse models and human T1D samples.
  • Discussion of mass spectrometry techniques for HIP identification.

Main Results:

  • HIPs are implicated as critical autoantigens in type 1 diabetes.
  • HIP-reactive T cells are involved in diabetes development.
  • HIPs present unique challenges and opportunities for T1D research.

Conclusions:

  • HIPs are significant targets for understanding and potentially treating T1D.
  • Further research into HIP generation and detection is crucial.
  • Targeting HIP-specific T cell responses may offer therapeutic strategies for T1D.
