enzyme
any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions
substrate
the substance that is acted upon by an enzyme or ferment
acid
any of various water-soluble compounds having a sour taste and capable of turning litmus red and reacting with a base to form a salt
base
lowest support of a structure
alkaline
relating to or containing an alkali; having a pH greater than 7
amphoteric
having characteristics of both an acid and a base and capable of reacting as either
isomer
a compound that exists in forms having different arrangements of atoms but the same molecular weight
enantiomer
either one of a pair of compounds (crystals or molecules) that are mirror images on each other but are not identical
reaction
an idea evoked by some experience
balance
harmonious arrangement or relation of parts or elements within a whole (as in a design)
equation
a mathematical statement that two expressions are equal
formula
a group of symbols that make a mathematical statement
molecule
(physics and chemistry) the simplest structural unit of an element or compound
atom
(physics and chemistry) the smallest component of an element having the chemical properties of the element
atomic

molar
grinding tooth with a broad crown; located behind the premolars
molarity
concentration measured by the number of moles of solute per liter of solution
molal

molality
concentration measured by the number of moles of solute per kilogram of solvent
proton
a stable particle with positive charge equal to the negative charge of an electron
neutron
an elementary particle with 0 charge and mass about equal to a proton; enters into the structure of the atomic nucleus
electron
an elementary particle with negative charge
positron
an elementary particle with positive charge; interaction of a positron and an electron results in annihilation

orbital
of or relating to an orbit
litmus
a coloring material (obtained from lichens) that turns red in acid solutions and blue in alkaline solutions; used as a very rough acid-base indicator
chelate
a heterocyclic compound having a metal ion attached by coordinate bonds to at least two nonmetal ions
chelation
the process of forming a ring by forming one or more hydrogen bonds
ligand
