    en.wikipedia.org/wiki/Numeric_precision_in...

    Excel's storage of numbers in binary format also affects its accuracy. [3] To illustrate, the lower figure tabulates the simple addition 1 + x − 1 for several values of x. All the values of x begin at the 15 th decimal, so Excel must take them into account. Before calculating the sum 1 + x, Excel first approximates x as a binary number

    A primary imine in which C is attached to both a hydrocarbyl and a H (derived from an aldehyde) is called a primary aldimine; a secondary imine with such groups is called a secondary aldimine. [10] A primary imine in which C is attached to two hydrocarbyls (derived from a ketone) is called a primary ketimine; a secondary imine with such groups ...

  9. Imine reductase - Wikipedia

    en.wikipedia.org/wiki/Imine_reductase

    An imine reductase (IRED) is an enzyme that reduces imines to amines. [ 1 ] [ 2 ] This family of enzymes is employed in the industrial production of amine -containing pharmaceuticals . [ 3 ] The IRED enzymes that are found to catalyze both imine formation and imine reduction are called reductive aminases (RedAms).
