Fatty acid methyl esters (FAME) are a type of fatty acid ester that are derived by transesterification of fats with methanol. The molecules in biodiesel are primarily FAME, usually obtained from vegetable oils by transesterification. They are used to produce detergents and biodiesel. [1]
Aspartame is an artificial non-saccharide sweetener commonly used as a sugar substitute in foods and beverages. [4] 200 times sweeter than sucrose, it is a methyl ester of the aspartic acid/phenylalanine dipeptide with brand names NutraSweet, Equal, and Canderel. [4]
The most commonly used alcohol is methanol, producing fatty acid methyl esters (FAME). When ethanol is used fatty acid ethyl esters (FAEE) are created. Other alcohols used for the production of biodiesel include butanol and isopropanol. Fatty acid ethyl esters are biomarkers for the consumption of ethanol (alcoholic beverages). [1] [2] [3]
Methylparaben is commonly used as a fungicide in Drosophila food media at 0.1%. [5] To Drosophila , methylparaben is toxic at higher concentrations, has an estrogenic effect (mimicking estrogen in rats and having anti- androgenic activity), and slows the growth rate in the larval and pupal stages at 0.2%.
Methyl acrylate is after butyl acrylate and ethyl acrylate the third most important acrylic ester with a worldwide annual production of about 200,000 tons in 2007. [16] Poly(methyl acrylate) is a tacky material near room temperature, and as such it is not particularly useful as a structural material.
An ester of a carboxylic acid. R stands for any group (typically hydrogen or organyl) and R ′ stands for any organyl group. In chemistry, an ester is a compound derived from an acid (organic or inorganic) in which the hydrogen atom (H) of at least one acidic hydroxyl group (−OH) of that acid is replaced by an organyl group (R ′). [1]
Methyl salicylate (oil of wintergreen or wintergreen oil) is an organic compound with the formula C 8 H 8 O 3.It is the methyl ester of salicylic acid.It is a colorless, viscous liquid with a sweet, fruity odor reminiscent of root beer (in which it is used as a flavoring), [4] but often associatively called "minty", as it is an ingredient in mint candies. [5]
The conversion of methyl acetate back into its components, by an acid, is a first-order reaction with respect to the ester. The reaction of methyl acetate and a base, for example sodium hydroxide, is a second-order reaction with respect to both reactants. Methyl acetate is a Lewis base that forms 1:1 adducts with a variety of Lewis acids.
