Representative triglyceride found in a linseed oil, a triester (triglyceride) derived of linoleic acid, alpha-linolenic acid, and oleic acid. Linseed oil is a triglyceride, like other fats. Linseed oil is distinctive for its unusually large amount of α-linolenic acid, which oxidises in air.
These are triglyceride-based, and include cooking oils like canola oil, solid oils like cocoa butter, oils used in paint like linseed oil and oils used for industrial purposes. Pressed vegetable oils are extracted from the plant containing the oil (usually the seed), using one of two types of oil press.
A triglyceride (from tri-and glyceride; also TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids. [1] Triglycerides are the main constituents of body fat in humans and other vertebrates as well as vegetable fat . [ 2 ]
Flax, flax seeds, linseed oil, linseed cake. Linseed oil, also known as flaxseed oil or flax oil (in its edible form), is a colorless to yellowish oil obtained from the dried, ripened seeds of the flax plant (Linum usitatissimum). The oil is obtained by pressing, sometimes followed by solvent extraction.
Such a triglyceride has a high iodine value (approx. 119). Below, the reaction product after the addition of four equivalents of iodine or bromine to the four C=C double bonds of the unsaturated fatty acid residues. The determination of iodine value is a particular example of iodometry. A solution of iodine I 2 is yellow/brown in color.
Alkyds are derived from polyols and organic acids including dicarboxylic acids or carboxylic acid anhydride and triglyceride oils. The term alkyd is a modification of the original name "alcid", reflecting the fact that they are derived from alcohol and organic acids. [2] The inclusion of a fatty acid confers a tendency to form flexible coatings.
Linseed oil, from flax seeds; Rice bran oil, from rice grains; Safflower oil, a flavorless and colorless cooking oil; Sesame oil, used as a cooking oil, and as a massage oil, particularly in India; Açaí palm oil, used in culinary and cosmetics; Jambú oil, is extracted from the flowers, leaves and stem from jambu (Acmella oleracea), contains ...
There are a limited number of naturally occurring vegetable oils (triglycerides) which contain the unreacted hydroxyl groups that account for both the name and important reactivity of these polyols. Castor oil is the only commercially available natural oil polyol that is produced directly from a plant source: all other NOPs require chemical ...
