molecular formula
An expression representing the composition of elements in a chemical substance commonly consisting of a series of letters and numbers comprising the atomic symbols of each element present in a compound followed by the number of atoms of that element present in one molecule of the substance Thus the molecular formula for common alcohol ethyl alcohol is C2H6O meaning that each molecule contains two carbon atoms six hydrogen atoms and one oxygen atom The molecular formula may be written to provide some indication of the actual structure of the molecule in which case structural units may be written separately Thus ethyl alcohol can also be written as CH3CH2OH or CH3 CH2 OH in which the period or dash between functional groups indicates a single bond between the principle atoms of each group This formula shows that in ethyl alcohol the carbon of a methyl group CH3 is attached to the carbon of a methylene group CH2 which is attached to the oxygen of a hydroxyl group OH A structural formula i...

monomer
The basic conceptual building unit of a polymer a molecule of low molecular weight which may combine with other molecules to form a molecule in a chain or branched form having high molecular weight as amino acids are the monomer units which are combined to form proteins vinylic plastics are formed from monomers having a vinyl group...
designer drug
designer drug : a synthetic version of a controlled substance (as heroin) that is produced with a slightly altered molecular structure to avoid having it classified as an illegal drug ...
deoxyribonucleic acid
a nucleic acid usually of very high molecular weight consisting of a linear sequence of monomer units of deoxyribonucleotides occurring in most organisms in pairs of strands wound together in the form of a double helix it is the main component of chromosomes and contains the genetic information which is the basis of heredity transmitted from parent to progeny and found in all living organisms except for certain viruses which have RNA as their basic genetic material usually referred to by the acronym DNA...

Heat
A force in nature which is recognized in various effects but especially in the phenomena of fusion and evaporation and which as manifested in fire the suns rays mechanical action chemical combination etc becomes directly known to us through the sense of feeling In its nature heat is a mode of motion being in general a form of molecular disturbance or vibration It was formerly supposed to be a subtile imponderable fluid to which was given the name caloric...
isomeric
Having the same chemical composition and molecular weight having the same number of atoms of each kind in the molecule said of chemical compounds with known chemical composition This property used to be called metameric to distinguish it from other forms of isomerism...
mass spectrometer
An analytical instrument which determines the mass of molecules of a substance or fragments of its molecules It functions by injecting ionized moecules or molecular gragments into a vacuum chamber subjected to a strong magnetic field in which charged particles move in a curved trajectory...
