macromolecule, term that may refer either to a crystal crystal, a solid body bounded by natural plane faces that are the external expression of a regular internal arrangement of constituent atoms, molecules, or ions. .....

There is a chemical bond between two atoms or groups of atoms when the forces acting between them are strong enough to lead to the formation of an aggregate with sufficient stability to be regarded as .....

Macromolecules such as proteins and nucleic acids are vital to the functions of living cells. macromoleculeAny very large molecule, composed of much larger numbers (hundreds or thousands) of atoms than ordinary molecules. Some macromolecules are individual entities that cannot be subdivided without losing their identity (e.g., certain proteins, with molecular weights into the millions). Others (polymers) are multiples of a repeating building block (monomer) in chains or networks (e.g., plastics, cellulose). Most macromolecules are in the size range typical of colloids. macromolecule any very large molecule, such as a protein or synthetic polymer macromolecule [¦mak·rō′mäl·ə‚kyül] (organic chemistry) A large molecule in which there is a large number of one or several relatively simple structural units, each consisting of several atoms bonded together.

It is an acronym for deoxyribonucleic acid--a macromolecule that acts like a blueprint or instruction manual for the functions of your cells. The statistics concentrate mainly upon chain molecular properties, whereby the macromolecule is supposed to have a random shape in space, thus relating to stochastic concepts like random walk or Brownian motion. Incorporation values were corrected to the amount of DNA present in each culture to provide an index of macromolecule synthesis per cell. |
