In chemistry, an amphiphile (from Greek αμφις (amphis) 'both' and φιλíα (philia) 'love, friendship'), or amphipath, is a chemical compound possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving, nonpolar) properties. [1] . Such a compound is …

The meaning of AMPHIPHILIC is of, relating to, or being a compound (such as a surfactant) consisting of molecules having a polar water-soluble group attached to a water-insoluble hydrocarbon chain; also : being a molecule of such a compound.

2020年2月7日 · Amphipathic or amphiphilic molecules have parts that are polar and nonpolar, making them both hydrophilic and lipophilic. Examples of amphipathic molecules include surfactants, phospholipids, and bile acids.

2023年5月4日 · Amphiphilic molecules are molecules that have a distinct separation between hydrophobic and hydrophilic regions. The hydrophilic portion of an amphiphilic molecule is usually a charged or a polar group, while the hydrophobic portion is a non-polar group such as a hydrocarbon chain.

Amphiphilic molecules are essential components of cell membranes, forming the lipid bilayer structure. Phospholipids are a common example of amphiphilic molecules, with a hydrophilic phosphate head and hydrophobic fatty acid tails.

Describe the role of amphiphilic molecules in the context of soap and their ability to remove dirt and grease from surfaces. The amphiphilic nature of soap molecules is crucial to their cleaning ability.

What is the structural characteristic that defines an amphiphilic molecule? How do amphiphilic molecules behave when placed in water, and what structure do they form? What practical applications utilize amphiphilic substances?

2024年4月5日 · Amphiphilic, a term often used interchangeably with amphipathic, generally describes molecules that have an affinity for both water and lipid environments but is sometimes used to emphasize the molecule's ability to dissolve or interact favorably with both polar and nonpolar substances.

2022年10月12日 · Amphiphile (from the Greek αμφις, amphis: both and φιλíα, philia: love, friendship) is a term describing a chemical compound possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving) properties. Such a compound is called amphiphilic or amphipathic.

Denoting a molecule, such as comprises detergents or wetting agents, which contains groups with characteristically different properties, for example, both hydrophilic and hydrophobic properties. Synonym (s): amphiphilic, amphiphobic. [amphi- + G. pathos, feeling]
