The general structure of a phosphite ester showing the lone pairs on the P. In organic chemistry, a phosphite ester or organophosphite usually refers to an organophosphorous compound with the formula P(OR) 3. They can be considered as esters of an unobserved tautomer phosphorous acid, H 3 PO 3, with the simplest example being trimethylphosphite ...
Studies on alcohol and weight loss are mixed, however. One 2020 analysis of more than 280,000 people found that those who drank wine had lower BMIs than those who didn’t drink wine.
Various specialised methods have been developed on the laboratory-scale for scientific investigations. These are rarely employed in bulk manufacturing. Examples include the Atherton-Todd reaction, which converts a dialkyl phosphite to a phosphoryl chloride. This can then react with an alcohol to give an organophosphate and HCl.
Phosphate esters have the general structure P(=O)(OR) 3 feature P(V). Such species are of technological importance as flame retardant agents, and plasticizers. Lacking a P−C bond, these compounds are in the technical sense not organophosphorus compounds but esters of phosphoric acid. Many derivatives are found in nature, such as ...

The relationship between alcohol consumption and body weight is the subject of inconclusive studies. Findings of these studies range from increase in body weight to a small decrease among women who begin consuming alcohol. [1] [2] Some of these studies are conducted with numerous subjects; one involved nearly 8,000 and another 140,000 subjects.
Alcohol: such as beer, wine, spirits, and other alcoholic beverages. While moderate amounts can lead to body weight gain, chronic consumption of large amounts of alcohol can lead to body weight loss because alcoholic liver disease (ALD) is characterized by an increased metabolic rate and impaired muscle protein synthesis, resulting in sarcopenia .
Triethyl phosphite (TEP) is an organophosphorus compound, specifically a phosphite ester, with the formula P(OCH 2 CH 3) 3, often abbreviated P(OEt) 3. It is a colorless, malodorous liquid. It is used as a ligand in organometallic chemistry and as a reagent in organic synthesis.
