base

 [bās]
1. the lowest part or foundation of anything. See also basis.
2. the main ingredient of a compound.
3. the nonacid part of a salt; a substance that combines with acids to form salts. In the chemical processes of the body, bases are essential to the maintenance of a normal acid-base balance. Excessive concentration of bases in the body fluids leads to alkalosis.
4. a unit of a removable dental prosthesis.
5. in genetics, a nucleotide, particularly one in a nucleic acid sequence.
intermediary base the layer of cement between a dental restoration and the tooth structure, acting as an insulator and protective barrier.
nitrogenous base an aromatic, nitrogen-containing molecule that serves as a proton acceptor, e.g., purine or pyrimidine.
ointment base a vehicle for the medicinal substances carried in an ointment.
purine b's a group of compounds of which purine is the base, including uric acid, adenine, xanthine, and theobromine.
Bases. A, Purine and some substituted purine bases occurring in nucleic acids. B, Pyrimidine and some substituted pyrimidine bases occurring in nucleic acids. From Dorland's, 2000.
pyrimidine b's a group of chemical compounds of which pyrimidine is the base, including uracil, thymine, and cytosine, which are common constituents of nucleic acids.

base

A chemical compound that combines with an acid to form a salt and water. A term applied in genetics to one of the four nitrogenous bases of DNA and RNA. In DNA the bases are adenine, thymine, guanine and cytosine. Guanine and adenine are purines and cytosine and thymine are pyrimidines. In RNA, the pyrimidine base uracil replaces thymine. (See also BASE PAIR).

base

  1. a chemical substance which has a tendency to accept protons (H+); the base dissolves in water with the production of hydroxyl ions and reacts with acids to form salts.
  2. one of the PURINE or PYRIMIDINE components of NUCLEOTIDES.
