An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond.
Crotonic acid has 4 carbons, is included in croton oil, and is a trans-2-mono-unsaturated fatty acid.C 3 H 5 CO 2 H, IUPAC organization name (E)-but-2-enoic acid, trans-but-2-enoic acid, numerical representation 4:1, n-1, molecular weight 86.09, melting point 72–74 °C, boiling point 180–181 °C, specific gravity 1.027.
The effect of this is that, in restricted environments, such as when fatty acids are part of a phospholipid in a lipid bilayer or triglycerides in lipid droplets, cis bonds limit the ability of fatty acids to be closely packed, and therefore can affect the melting temperature of the membrane or of the fat. Cis unsaturated fatty acids, however ...
Unsaturated fats are typically oils, including seed oils, and can be polyunsaturated or monounsaturated. Polyunsaturated fats include omega-3 fatty acids and omega-6 fatty acids.
However, since the fats and oils in most natural and traditionally processed foods contain both unsaturated and saturated fatty acids, [73] the complete exclusion of saturated fat is unrealistic and possibly unwise. For instance, some foods rich in saturated fat, such as coconut and palm oil, are an important source of cheap dietary calories ...
unsaturated fats. antioxidants and other plant compounds. certain vitamins and minerals. Waring suggested replacing animal fats with plant-based unsaturated fats can reduce cardiovascular disease ...
They don't make any scientific distinction between seed oils and other unsaturated fat sources, and they don't talk much about the importance of balancing essential fatty acids. Their unwavering ...
Because of their effects in the diet, unsaturated fats (monounsaturated and polyunsaturated) are often referred to as good fats; while saturated fats are sometimes referred to as bad fats. Some fat is needed in the diet, but it is usually considered that fats should not be consumed excessively, unsaturated fats should be preferred, and ...
