  <description>Alpha tocopherol (C29H50O2) is a compound with an average molecular weight of 430.72 g/mol. Alpha tocopherol belongs to the quinone and hydroquinone lipids, a subclass of prenol lipids within the organic compounds. Industrially, it is utilized as a fragrance, preservative, softener, and conditioner, as well as an antioxidant (PMC10855613, PMC3257702, PMC4104792, PMC4428026, PMC5651431, PMC7550371, PMC8980384). It also serves as a biological antioxidant (PMC10855613, PMC3257702, PMC4104792, PMC4428026, PMC5651431, PMC7550371, PMC8980384) and an environmental nutrient (PMC3257702).

The compound is found in or released from 29 recorded sources. These include household cleaning and consumer products such as bleaching agents, perfumes within detergents and soaps, cigar cigarettes, non electric simulated smoking devices, and other smoking requisites. It is also associated with food, food processing and cookware, specifically food preservation and the preparation of malt, vinegar, wine or sparkling wine, as well as fermentation processes for beer. Additionally, it is found in electrical and electronic equipment, including antennas, coils, electric hearing aids, communication cables or conductors, and conductors or conductive bodies characterised by the conductive materials.

Regarding health effects, alpha tocopherol is associated with lung disease (PMC4384764), heart disease (PMC6259353), and atherosclerosis (PMC7932781). It is linked to a decrease in asthma (PMC4299629, PMC9025817) and cancer (PMC2763252, PMC3257702). Furthermore, it is used as a treatment for male infertility (PMC9005387) and epilepsy (PMC4428026), and it has a therapeutic effect on myocardial infarction (PMC4315737).</description>
