How to use hydrophobic in a sentence. The following article is from The Great Soviet Encyclopedia (1979). This entry appears with permission from the Dictionary of Cell and Molecular Biology (11 Mar 2008) Lexicographical Neighbors of Hydrophobic Hydrophobic definition, of or relating to hydrophobia. 4 is negative as the distortion of hydrogen bond network near the folded protein becomes less severe. Nonpolar molecules that repel the water molecules are said to be hydrophobic; molecules forming ionic or a hydrogen bond with the water molecule are said to be hydrophilic. This is driven by the tendency for water molecules to "want" to hydrogen bond in combination with an inability to do so with these hydrophobic substances. Definition of Hydrophobic bond with photos and pictures, translations, sample usage, and additional links for more information. 1. The energetics of hydrophobic bond formation drives amino acids with hydrophobic sidechains into the interior of proteins, in most cases; this is a very important component of proper protein folding. Hydrogen bond definition is - an electrostatic attraction between a hydrogen atom in one polar molecule (as of water) and a small electronegative atom (as of oxygen, nitrogen, or fluorine) in usually another molecule of the same or a different polar substance. Hydrophobic definition is - of, relating to, or suffering from hydrophobia. This bond always involves a hydrogen atom. permit's take a closer have a look at that definition. All of the other answers use lots of words but no pictures. Hydrogen bonds can occur between molecules or within parts of a single molecule. The tendency of nonpolar molecules in a polar solvent (usually water) to interact with one another is called the hydrophobic effect.The interactions between the nonpolar molecules are called hydrophobic interactions.The relative hydrophobicity of amino acid residues is defined by a system known as hydrophobicity scales.. General Information [] Search the Dictionary for More Terms. Ionic bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. 1. Ionic bond definition, the electrostatic bond between two ions formed through the transfer of one or more electrons. Definition of hydrophobic interaction. hydrophytic leaves The leaves of plant s that grow in water or under conditions of … Not readily absorbing water or being adversely affected by water, as a hydrophobic colloid. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. Definition of Hydrophobic. Hydrophobic interaction synonyms, Hydrophobic interaction pronunciation, Hydrophobic interaction translation, English dictionary definition of Hydrophobic interaction. Hydrogen Bond Definition . Hydrophobic Interactions. See more. Related terms: Hydrogen; Hydrocarbon; Protein; Ligand; Surfactant; Ion; Solubility; Micelle; Solute; Hydrogen Bond The molecule increasingly becomes overall more nonpolar and therefore less soluble in the polar water as the carbon chain becomes longer. See more. water, nonpolar molecules bond weakly with each other. Examples of hydrophobic molecules include the alkanes, oils, fats, … Hydrophilic Definition. Hydrophobic coatings can be easily applied over any substrate such as glass, metal, wood, and plastic irrespective of its composition and can also be applied to complex geometries. Hydrophobic Coatings - Paint Protection - the Next Generation Hydrophobic Coatings thin layers of a waterproof substance on the surface of hydrophilic materials. Hydrophobic surface is a surface that has the ability to repel water [1]. Repelling, tending not to combine with, or incapable of dissolving in water. From: The Journal of Supercritical Fluids, 2007. A hydrophilic molecule or substance is attracted to water. Water is a polar molecule that acts as a solvent, dissolving other polar and hydrophilic substances.In biology, many substances are hydrophilic, which allows them to be dispersed throughout a cell or organism.All cells use water as a solvent that creates the solution known as cytosol. This property of water was important for the evolution of life. Hydrophobic exclusion describes the tendency, for example, of multiple oil droplets in water to coalesce into fewer, larger droplets. As chemical bond like hydrogen bond is broken down in this reaction and releases energy, so it is considered as an endothermic reaction, and this whole process causes the entropy of the system to decrease. The term hydrophobic literally means "fearing water" and it describes the separation of water and non-polar substances, which maximizes the hydrogen bonding between molecules of water and minimizes the area of contact between water and non-polar molecules. Then the tubes were added to 5 mL of four chemical solutions: solution A (SA) 0.05 M NaCl; solution B (SB) 0.6 M NaCl; solution C (SC) 1.5 M urea+0.6 M NaCl; solution D (SD) 8.0 M urea+0.6 M NaCl, which disrupted some bond types including ionic bonding, hydrogen bonding and hydrophobic interactions.Proteins were partially solubilized in these solutions to measure the existence of ionic … Because of very small differences in charge distribution that are produced by covalent bonds between two atom of similar, but slightly different electronegativies. Soap micelles mobilize fats and other hydrophobic substances by dissolving them in the interior of the micelle. Phospholipid Definition. Hydrophobic molecules tend to be nonpolar and, thus, prefer other neutral molecules and nonpolar solvents.Because water molecules are polar, hydrophobes do not dissolve well among them. hydrophobic synonyms, hydrophobic pronunciation, hydrophobic translation, English dictionary definition of hydrophobic. Currently experimental data (e.g. It might be outdated or ideologically biased. [adj] Medical Definition of Hydrophobic. 2. rabid . from X-ray crystallography or NMR) are scarce and can not distinguish between various existing models of hydrophobic effect. Define hydrophobic. 1. Repelling, tending not to combine with, or incapable of dissolving in water. Definition []. Oxygen, as an electronegative atom, draws the electrons of each bond closer to its core, thus creating a more negative charge. hydrophobic Water-fearing.Term applied to nonpolar molecules that cannot bond with water. The hydrophobic part of the solvent-accessible surface of a typical monomeric globular protein consists of a single, large interconnected region formed from faces of apolar atoms and constituting approximately 60% of the solvent-accessible surface area. These forces come about when two areas of 2 different molecules containing hydrophobic sections come close together. losing a water in order to form a bond; used with sugars, nucleic acids, & amino acid -> puts them together; A chemical reaction in which two molecules covalently bond to each other with the removal of a … Thus creating a more negative charge object being cleaned dictionary definition of hydrophobic effect ( ).
