Paraffin waxes are mixtures of saturated n- and iso- alkanes, naphthenes, and alkyl- and naphthene-substituted aromatic compounds. A typical alkane paraffin wax chemical composition comprises hydrocarbons with the general formula C n H 2n+2, such as hentriacontane, C 31 H 64. The degree of branching has an important influence on the properties.
Epicuticular wax forms crystalline projections from the plant surface, which enhance their water repellency, [11] create a self-cleaning property known as the lotus effect [12] and reflect UV radiation. The shapes of the crystals are dependent on the wax compounds present in them.
Beeswax is an ingredient in surgical bone wax, which is used during surgery to control bleeding from bone surfaces; shoe polish and furniture polish can both use beeswax as a component, dissolved in turpentine or sometimes blended with linseed oil or tung oil; modeling waxes can also use beeswax as a component; pure beeswax can also be used as ...
Fillets from these fish species contain up to 20% fat, where 90% of the fat comes as wax esters, resulting in a typical intake of more than 30 000 mg wax esters from one single meal. Orange roughy ( Hoplostethus atlanticus) is an attractive food fish with 5.5% fat, where 90% of the fat comes as wax esters.
Earwax, also known by the medical term cerumen, is a waxy substance secreted in the ear canal of humans and other mammals. Earwax can be many colors, including brown, orange, red, yellowish, and gray.
A biological membrane is a form of lamellar phase lipid bilayer. The formation of lipid bilayers is an energetically preferred process when the glycerophospholipids described above are in an aqueous environment.
The following list identifies in rank order the possible biological roles of the chemical elements, ranging from a score of 5 for elements essential to all living things, to a score of 1 for elements that have no known effects on living things. There are also letter scores for special functions of the elements.
In this sense, besides the triglycerides, the term would include several other types of compounds like mono-and diglycerides, phospholipids (such as lecithin), sterols (such as cholesterol), waxes (such as beeswax), [1] and free fatty acids, which are usually present in human diet in smaller amounts.
