Hydroperoxide - Wikipedia
网页Hydroperoxides or peroxols are compounds of the form ROOH, where R stands for any group, typically organic, which contain the hydroperoxy functional group (−OOH). Hydroperoxide also refers to the hydroperoxide anion (− OOH) and its salts, and the neutral hydroperoxyl radical (•OOH) consist of an unbond hydroperoxy group.
Hydroperoxide - an overview | ScienceDirect Topics
网页A hydroperoxide refers to an intermediate product that is formed during the decomposition of certain solvents, such as hydrocarbons, ethers, and low molecular weight alcohols. It is more stable than a peroxide radical and can easily decompose to produce free radicals, accelerating the degradation pathway.

Lipid Peroxidation and Antioxidant Protection - PMC
网页2023年8月24日 · Lipid peroxidation (LP) is a complex phenomenon, first investigated in the early 20th century, consisting in the uptake of molecular oxygen by lipids exposed to air, which was soon recognized as bearing remarkable similarity to hydrocarbon autoxidation [1, 2], the formal insertion of one molecule of oxygen in the C-H bond of a hydrocarbon to aff...

网页2014年5月8日 · Hydroperoxides are produced during the propagation phase constituting the major primary product of lipid peroxidation process. The hydroperoxide group may be attached to various lipid structures, for example, free fatty acids, triacylglycerols, phospholipids, and sterols.
Hydroperoxide - an overview | ScienceDirect Topics
网页In nonspecific reactions involving heavy metal ions, heme (in) compounds or proteins, hydroperoxides are transformed into oxo, epoxy, mono-, di-and trihydroxy carboxylic acids. Unlike hydroperoxides, i.e., the primary products of autoxidation, some of these derivatives have a bitter taste.
