Mathematical modelling of the vitamin C clock reaction: a study of two kinetic regimes [PDF]

arXiv
Chemically reacting systems exhibiting a repeatable delay period before a visible and sudden change are referred to as clock reactions; they have a long history in education and provide an idealisation of various biochemical and industrial processes. We focus on a purely substrate-depletive clock reaction utilising vitamin C, hydrogen peroxide, iodine ...

Glutathione Peroxidases: An Emerging and Promising Therapeutic Target for Pancreatic Cancer Treatment

Antioxidants
Glutathione peroxidases (GPxs) are a family of enzymes that play a critical role in cellular redox homeostasis through the reduction of lipid hydroperoxides to alcohols, using glutathione as a substrate.

Mechanisms and active substances of targeting lipid peroxidation in ferroptosis regulation

Food Science and Human Wellness
Ferroptosis is a novel form of cell death driven by iron-dependent lipid peroxidation and it is implicated in various diseases, such as liver disease, acute kidney injury, cardiovascular disease, neurodegenerative disease and cancer. Lipid-based reactive

Oxidants and antioxidants in atherogenesis: an appraisal

Journal of Lipid Research, 1999
Oxidized low density lipoprotein (Ox-LDL) has a plethora of components that are not present in native LDL. Their presence and quantity depends on the nature, type, and extent of oxidation.

Flexible String Model of Unsaturated Lipid Bilayer [PDF]

arXiv
An analytically solvable model of unsaturated lipid bilayer is derived by introducing finite bending angle of the unsaturated bond relative to straight part of the lipid chain considered previously in our model of semi-flexible strings. It is found that lateral pressure profile of unsaturated lipids has distinct maximum in the unsaturated bond region ...

Impact of Lipid Structural Variations on Bilayer Properties: A Coarse-Grained Molecular Dynamics Study [PDF]

arXiv
The supramolecular assembly of lipids into bilayer membranes is essential for cellular structure and function. However, the impact of lipid structural variations such as acyl chain length, degree of unsaturation, and headgroup type on bilayer properties remains incompletely understood.
