In biochemistry and nutrition, a monounsaturated fat is a fat that contains a monounsaturated fatty acid (MUFA), a subclass of fatty acid characterized by having a double bond in the fatty acid chain with all of the remaining carbon atoms being single-bonded. By contrast, polyunsaturated fatty acids (PUFAs) have more than one double bond.
Palmitoleic acid has 16 carbons, is found in cod liver oil, sardine oil, and herring oil, and is a cis-9-monounsaturated fatty acid. C 15 H 29 CO 2 H, IUPAC organization name (Z)-hexadec-9-enoic acid, n-7, numerical representation of 16:1, molecular weight 254.41, melting point 5 °C, specific gravity 0.894. CAS Registry Number 373-49-9.
Stearoyl-CoA desaturase (Δ-9-desaturase or SCD-1) is an endoplasmic reticulum enzyme that catalyzes the rate-limiting step in the formation of monounsaturated fatty acids (MUFAs), specifically oleate and palmitoleate from stearoyl-CoA and palmitoyl-CoA. [1]
It is an odorless, colorless oil, although commercial samples may be yellowish due to the presence of impurities. In chemical terms, oleic acid is classified as a monounsaturated omega-9 fatty acid, abbreviated with a lipid number of 18:1 cis-9, and a main product of Δ9-desaturase. [2] It has the formula CH 3 −(CH 2) 7 −CH=CH−(CH 2) 7 ...
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.
Eat this instead: Choose healthier monounsaturated fats, such as olive oil, and increase your intake of foods that contain unsaturated omega-3 fatty acids, like chia seeds, flax seeds, and fish.
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.
Unsaturated fatty acids are further classified into monounsaturated (MUFAs), with a single double bond, and polyunsaturated (PUFAs), with two or more. [ 10 ] [ 11 ] Natural fats usually contain several different saturated and unsaturated acids, even on the same molecule.
