fatty acid molecules. Free rotation around the carbon-carbon bond in the saturated fatty acids gives the hydrocarbon chain great flexibility; thereby, the steric hindrance is low. These atoms/molecules are packed together byvan der Waals forcesin nearly crystalline arrays, whereas in unsaturated fatty...
Fatty acids are organic compounds consisting of a hydrocarbon chain with a carboxyl group at one end. Fatty acids are saturated if the hydrocarbon tail has only single bonds. Unsaturated fatty acids will have one or more double bond in the hydrocarbon tail. A...
hydrocarbon-tail chain length than the number (1 or 2) of rhamnose groups. Similar to synthetic surfactants, rhamnolipids can reduce surface and interfacialtensionsand offer detergent, emulsifying, foaming, and/or dispersing properties for different applications. The minimal surface tension in aqueous ...
Fatty amines are a class of organic compounds that are derived from fatty acids and have an amino group (-NH2) attached to a hydrocarbon chain. They are commonly used in various industrial applications, including surfactants, corrosion inhibitors, and flotation agents. Fatty amines can be synthesiz...
2-Hydroxytetracosanoic acid (cerebronic acid) and 2-hydroxy-15-tetracosenoic acid (hydroxynervonic acid) are constituents of the ceramide part of cerebrosides (glycosphingolipides found mainly in nervous tissue and in little amount in plants). ...
Fatty acids (FAs) are the main building blocks of several lipid species, including phospholipids, sphingolipids and triglycerides, and are composed of a carboxylic acid group and a hydrocarbon chain of varying carbon lengths and degrees of desaturation. They can be funnelled into various metabolic ...
The results further show that proteins either disorder or have little effect on hydrocarbon chain order in membranes above the gel-to-liquid crystal phase transition temperature, Tc, of the pure lipids. The question as to how an intrinsic protein affects the lipid environment was also investigated...
In another embodiment, the methods further comprise blending one or more of the medium chain length hydrocarbon fractions. Such blending can comprise any combination of medium chain length fatty acid fractions desired for a given purpose (ie: C10 and C12; C12 and C14; C10 and C14; C8, C10 ...
Nearly all are amphoteric in so far as they behave as both acid and base and more importantly all are amphipathic, having a water soluble, hydrophilic end at the polar head group and a fat soluble lipophylic end at the hydrocarbon tail....
Although bubble size measurements in bulk solution pointed towards quite similar gas dispersing abilities of the tested surfactants, their foamabilities under the same conditions were remarkably enhanced with increasing chain length of the hydrocarbon tail. Shorter chain surfactants - hexanoate and laurate ...
