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 this shape. In chemistry, an amphiphile (from Greek αμφις (amphis) 'both' and φιλíα 'love, friendship'), or amphipath, is a chemical compound possessing both hydrophilic ...
An example of these amphiphilic molecules is the lipids that comprise the cell membrane. Another example is soap, which has a hydrophilic head and a hydrophobic tail, allowing it to dissolve in both water and oil. Hydrophilic and hydrophobic molecules are also known as polar molecules and nonpolar molecules, respectively. Some hydrophilic ...
In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions and negatively charged ions , [1] which results in a compound with no net electric charge (electrically neutral). The constituent ions are held together by electrostatic forces termed ionic bonds.
Micellar chemistry uses the interior of micelles to harbor chemical reactions, which in some cases can make multi-step chemical synthesis more feasible. [ 22 ] [ 23 ] Doing so can increase reaction yield, create conditions more favorable to specific reaction products (e.g. hydrophobic molecules), and reduce required solvents, side products, and ...
The term "Janus Particle" was coined by author Leonard Wibberley in his 1962 novel The Mouse on the Moon as a science-fictional device for space travel.. The term was first used in a real-world scientific context by C. Casagrande et al. in 1988 [8] to describe spherical glass particles with one of the hemispheres hydrophilic and the other hydrophobic.
Some common shapes of simple molecules include: Linear: In a linear model, atoms are connected in a straight line. The bond angles are set at 180°. For example, carbon dioxide and nitric oxide have a linear molecular shape. Trigonal planar: Molecules with the trigonal planar shape are somewhat triangular and in one plane (flat). Consequently ...
If a compound dissolves in water, then it is considered to be hydrophilic. [6] Zinc chloride and calcium chloride, as well as potassium hydroxide and sodium hydroxide (and many different salts), are so hygroscopic that they readily dissolve in the water they absorb: this property is called deliquescence.
Sodium chloride (table salt, rock salt) – NaCl; Sodium chlorite – NaClO 2; Sodium hypochlorite – NaOCl; Sodium perchlorate – NaClO 4; Strontium chloride – SrCl 2; Sulfur dichloride – SCl 2; Sulfuryl chloride – SO 2 Cl 2; Tantalum(III) chloride – TaCl 3; Tantalum(IV) chloride – TaCl 4; Tantalum(V) chloride – TaCl 5; Tellurium ...
