Amphipathic

amphipathic Definition of amphipathic This describes a molecule which possesses both hydrophilic and hydrophobic elements.

Amphipathic: Structures that have two surfaces:one hydrophilic and one hydrophobic. Amplicon: ...

Amphipathic: A molecule that has both a hydrophobic and a hydrophilic part. Analogy: A similarity due to convergent evolution (common function) but not due to having a common ancestor (bat's wings and bird's wings). See also homology.

amphipathic molecule A molecule that has both a hydrophilic region and a hydrophobic region. anabolic steroids ...

amphipathic Adjective to describe a molecule with one part soluble in water (polar) and another part insoluble in water (nonpolar). amphipods A group of small, laterally compressed crustaceans that includes beach hoppers and others.

3 Amphipathic character 4 See also 5 References [edit] Components They are built upon to a nitrogen-containing alcohol like ethanolamine or an organic compound such as choline.

bile salts Amphipathic steroid derivatives with detergent properties, participating in digestion and absorption of lipids. Full article ...

An aggregate of amphipathic molecules in water, with the nonpolar portions in the interior and the polar portions at the exterior surface, exposed to water. A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ...

bilayer A double layer of amphipathic lipid molecules which orient themselves so the hydrocarbon tails face inward to form a continuous nonpolar phase and the polar head groups face outward. In this way they form the basic structure of membranes.

Such sequences form amphipathic a-helices, which assemble into helical bundles via knobs-into-holes interdigitation of residues from neighbouring helices.

(Science: cell biology) amphipathic, surface active, molecules with polar (water soluble) and nonpolar hydrophobic) domains. They bind strongly to hydrophobic molecules or molecular domains to confer water solubility.

transmembrane proteins - amphipathic proteins that extend through the bilayer with part of their mass on both sides of the bilayer acetyl coenzvme A (acetylCoA)-small water-soluble molecule that carries acetyl groups in cells.

The substitution Arg173----Cys in the AIMilano dramatically alters the amphipathic nature of the modified alpha-helical fragment of apoprotein AI. The association rate with lipids is accelerated by an increased exposure of hydrophobic residues.
