Home Dictionary Name: monomermonomer
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...
oligomer
A molecule composed of a small number of linked monomer units a short polymer compounds called oligomers have less than one hundred monomer units and usually less than thirty Oligomers of increasing length are called dimer trimer tetramer pentamer hexamer heptamer octamer nonamer decamer etc In colloquial laboratory jargon they may also be referred to as nine mer ten mer eleven mer twelve mer etc especially for oligomers of greater than eight units...
butadiene
a gaseous hydrocarbon C4H6 it is used as a monomer unit in making synthetic rubbers...
cross link
a covalent bond that links two chains of atoms or two sections of one chain in a polymeric molecule the cross link is created by a third bond in a monomer unit in addition to the two bonds forming the polymeric chain a cross link may be internal to a single chain rather than between two otherwise unlinked chains as ultraviolet irradiation creates cross links between the two chains of a DNA double helix many enzymes have cross links formed by disulfide bonds polystyrene resins have their porosity controlled by the proportion of cross links Called also cross linkage...
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...
deoxyribonucleotide
an organic molecule consisting of a hereocyclic base attached to the 1 carbon of a deoxyribose ring with a phosphate group esterified at the 5 position of the deoxyribose Deoxyribonuceotides are the monomer units which make up deoxyribonucleic acid the molecule carrying the hereditary information in most organisms The most common forms of deoxyribonuceotide are thymidine 5prime phosphate abbreviated TMP deoxyadenosine 5prime phosphate abbreviated dAMP deoxyguanosine 5prime phosphate abbreviated dGMP and deoxycytidine 5prime phosphate abbreviated dCMP...
Monome
A monomial...
monomeric
Not linked to other molecules of the same kind having the property of a monomer Opposed to polymeric...
nucleoside
A type of molecule found in all living organisms present mostly in chemically combined form as a component of nucleic acids and also in smaller amounts in free form consisting of a pentose sugar bound to a purine or pyrimidine base two types of nucleoside ribonucleoside and deoxyribonucleoside are present The most common bases present in nucleosides are adenine cytosine uracil guanine and thymine and to a lesser extent hypoxanthine and other bases are found The most commmon ribonucleosides composed from these bases are called adenosine cytidine uridine and guanosine The forms esterified with orthophosphoric at the 5 position of the pentose are called nucleotides The nucleotides form the monomer units which are combined into DNA and RNA which carry the genetic information required for reproduction in all known organisms...
