Phospholipids, such as this glycerophospholipid, have amphipathic character. Cross-section view of the structures that can be formed by biological amphiphiles in aqueous solutions. Unlike this illustration, micelles are usually formed by non-biological, single-chain, amphiphiles, soaps or detergents, since it is difficult to fit two chains into ...
The alkoxide ion is a strong base so the proton is transferred from the carboxylic acid to the alkoxide ion, creating an alcohol: saponification part III. In a classic laboratory procedure, the triglyceride trimyristin is obtained by extracting it from nutmeg with diethyl ether. Saponification to the soap sodium myristate takes place using NaOH ...
Phosphates in detergent refers to the use of phosphates as an ingredient in a detergent product. The advantage of using phosphates in a consumer laundry detergent or dishwashing detergent is that they make detergents more efficient by chelating calcium and magnesium ions. [1]
Lecithin (/ ˈ l ɛ s ɪ θ ɪ n / LESS-ith-in; from the Ancient Greek λέκιθος lékithos "yolk") is a generic term to designate any group of yellow-brownish fatty substances occurring in animal and plant tissues which are amphiphilic – they attract both water and fatty substances (and so are both hydrophilic and lipophilic), and are ...
The vast heterogeneity of structures underlying this class of compounds makes generalizations difficult; they're a subclass of terpenoids, oxygenated derivatives of terpene hydrocarbons. Terpenes in turn are formally made up of five-carbon isoprene units (The alternate steroid base is a terpene missing a few carbon atoms). Derivatives are ...
[5] [11] The disadvantage is that it can be difficult to determine patterns in lipids that are not well oriented such as non-lamellar phases. Although this can be a limitation in producing electron density reconstructions in lipids, X-ray diffraction is still a reliable method for obtaining structural information and distinguishing between ...
The "cilantro soap gene" is a genetic factor that makes cilantro taste and smell like soap. A study from 23andMe reveals the OR6A2 gene as a possible cause for some people's distinct cilantro ...
The α-Helices and β-Sheets are commonly amphipathic, meaning they have a hydrophilic and a hydrophobic portion. This ability helps in forming tertiary structure of a protein in which folding occurs so that the hydrophilic sides are facing the aqueous environment surrounding the protein and the hydrophobic sides are facing the hydrophobic core ...
