Neutral fats, also known as true fats, are simple lipids that are produced by the dehydration synthesis of one or more fatty acids with an alcohol like glycerol. Neutral fats are also known as triacylglycerols, [ 1 ] these lipids are dense as well as hydrophobic due to their long carbon chain and are there main function is to store energy.
[2] [3] The most familiar type of animal sterol is cholesterol, which is vital to the structure of the cell membrane, and functions as a precursor to fat-soluble vitamins and steroid hormones. While technically alcohols, sterols are classified by biochemists as lipids ( fats in the broader sense of the term).
Although the term "lipid" is sometimes used as a synonym for fats, fats are a subgroup of lipids called triglycerides. Lipids also encompass molecules such as fatty acids and their derivatives (including tri-, di-, monoglycerides, and phospholipids), as well as other sterol -containing metabolites such as cholesterol .

Epoxide monomers may be cross linked with themselves, or with the addition of a co-reactant, to form epoxy; BPA is the monomer precursor for polycarbonate; Terephthalic acid is a comonomer that, with ethylene glycol, forms polyethylene terephthalate. Dimethylsilicon dichloride is a monomer that, upon hydrolysis, gives polydimethylsiloxane.
These trace amounts of alcohol range from 0.1 to 0.3 μg/mL in the blood of healthy humans, with some measurements as high as 1.6 μg/mL (0.002 g/L). [ 76 ] Auto-brewery syndrome is a condition characterized by significant fermentation of ingested carbohydrates within the body.
A young adult human's fat stores average between about 15–20 kg (33–44 lb), but varies greatly depending on age, sex, and individual disposition. [10] In contrast, the human body stores only about 400 g (0.9 lb) of glycogen , of which 300 g (0.7 lb) is locked inside the skeletal muscles and is unavailable to the body as a whole.
Cholesterol is the principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils. [3] [4]Cholesterol is biosynthesized by all animal cells [citation needed] and is an essential structural and signaling component of animal cell membranes.
