Definitions

  • WordNet 3.6
    • n hydrolysis 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

Webster's Revised Unabridged Dictionary
    • n Hydrolysis (Chem) A chemical process causing the splitting of a chemical bond by the addition of the elements of water. Where the bond which is split is not part of a ring structure, this process causes formation of two compounds from one compound plus water, as in the hydrolysis of the ester bonds of fats during saponification .

Century Dictionary and Cyclopedia
    • n hydrolysis A kind of chemical decomposition by which a compound is broken up and resolved into other compounds by taking up the elements of water. Thus, by hydrolysis cane-sugar takes up a molecule of water and is resolved into one molecule of dextrose and one of levulose.
