The degradation of certain biopolymers (proteins, complex sugars) by the chemical process that results in smaller polymers or monomers (such as amino acids or monosaccharides)
A chemical reaction that releases sugars, which are normally linked together in complex chains In ethanol production, hydrolysis reactions are used to break down the cellulose and hemicellulose in the biomass
Chemical weathering process that involves the reaction between mineral ions and the ions of water (OH- and H+), and results in the decomposition of the rock surface by forming new compounds, and by increasing the pH of the solution involve through the release of the hydroxide ions
Chemical decom- position of a substance involving the addition of water Hysteresis - The heat generated by rapid deformation of a vulcanized rubber part It is the difference between the energy of the deforming stress and the energy of the recovery cycle
hydrolysis (hì-dròl¹î-sîs), chemical reaction of a compound with WATER, usually resulting in the formation of one or more new compounds The most common hydrolysis occurs when a salt of a weak acid or weak base (or both) is dissolved in water Water ionizes into negative hydroxyl ions (OH-) and positive hydrogen ions (H+), which become hydrated to form positive hydronium ions (H3O+) The salt also breaks up into positive and negative ions, and the formed ions recombine 1
The chemical reaction between water and a compound usually a salt The hydroxyl from water combines with a cation from the compound resulting in hydrolysis to form a base The hydrogen from water reacts with the anion from the compound to form an acid
a chemical reaction in which water reacts with a compound to produce other compounds; involves the splitting of a bond and the addition of the hydrogen cation and the hydroxide anion from the water
(alc) (chem) The chemical process that breaks complex organic molecules into simple molecules For example, STARCH and CELLULOSE can be hydrolyzed by ACIDs or ENZYMEs to produce simple sugars, which can be FERMENTED to form ETHANOL F - hydrolyse S - hidrolisis
Chemical reaction in which water (H2O or HOH) and another reactant exchange functional groups to form two products, one containing the H and the other the OH. In most hydrolyses involving organic compounds, the other reactants and products are neutral; for example, an ester can be hydrolyzed to form a carboxylic acid and an alcohol. Such reactions are often accelerated by enzymes (as in much of digestion and metabolism in general) or other catalysts. In hydrolyses of compounds with ionic bonds, the nonwater reactants are salts, acids, or bases, participating in dissociation reactions
Chemical decomposition of a substance into other compounds requiring the addition of water Usually considered in the sense of chemical degradation of insulating materials under heat or pressure and in contact with moisture As for example, hydrolysis of polyester films and coatings
Literally, breaking down (lysis) by water A reaction in which a molecule (often an ester or an amide) is broken down into two or more smaller molecules through the reaction with one or more water molecules An example is the hydrolysis of ethyl acetate by water to give ethanol and acetic acid
