► linear

· This consists, basically, of, in other words it is a linear long-chain molecule much like Figure 7.· For all but linear molecules, external molecular motions - 3 translations and 3 rotations - account for 6 of these.· A linear molecule has only two rotations, and so it has 3N - 5 vibrational modes.· A simple case is that of the linear molecule.· Again linear symmetrical molecules are best.

► organic

· Chemists now know how to make most organic molecules in the laboratory, but the name has stuck.· One idea that has been suggested is that the precursors of life - complex organic molecules - arrived here from outer space.· Tannins, another kind of organic molecule, are used in the oil industry to make muds easier to drill.· When this happened, say Hoyle and Wickramasinghe, the organic molecules within the comets were spewed out over the land.· We know, too, that meteorites often do contain complex organic molecules.· Geologists believe that oil and coal are composed of organic molecules because they themselves are derived from living things.· None of these organic molecules shows evidence of originating from living matter.· But although organic molecules are the essential components of modern living things, they can not in isolation be considered living.

► other

· Normally the forces from one molecule are counterbalanced by equal attraction by other molecules but at an interface the forces become unbalanced.· The range of distances found for the other four molecules is given in parentheses.· Once self-replication had got under way molecules could pile on other more complex molecules in a loose association.· Ethylene is the feedstock from which other molecules are built by the chemical industry.· Each then acts as a template to which other simpler molecules become attached until each has once more become a double helix.

► simple

· The root mean square speeds of some simple molecules are shown in table 3.2.· In fact, they are rather simple molecules, the structure of which has long been known.· All of them ultimately start out as two very simple molecules, carbon dioxide and water.· Each then acts as a template to which other simpler molecules become attached until each has once more become a double helix.

► single

► small

· LabVision features interactive 3D building and editing of small molecules as well as proteins, carbohydrates, and nucleic acids.· The smaller sized molecules can slip in between the larger ones.· These give only limited vibrational information, and then only for small molecules.· Amino-acid sequencing is limited to smaller molecules, for example the endogenous opioid met-enkephalin with a molecular weight of 573.· Both are chains of small molecules called nucleotides.· This process is particularly effective where small molecules are involved, for the band-shapes and vibrational structure are often characteristic.· The fluidity of liquids consisting of large molecules is lower than those consisting of small molecules.· The smaller molecule acids are soluble in water.

► solvent

· Sometimes specific intermolecular complexes are formed, either between two sample molecules or between sample and solvent molecules.

NOUN► adhesion

· Flexibility and the location of ligand-binding sites close to the top of adhesion molecules may be a general feature of their organization.· Special molecules called adhesion molecules guide the migration of developing neurons and help them to make stable connections to other neurons.· This suggests a possible tumour suppressor function for this cell adhesion molecule.· However, the final, as yet small, family of cell adhesion molecules bind to carbohydrates.· An altered expression of such adhesion molecules may influence the aggressiveness of local infiltrative growth and metastasis in human cancers.· Families of cell adhesion molecules Many different cell adhesion molecules have been described.· Cell adhesion and disease adhesion molecule deficiency A number of rare diseases result from defects in adhesion molecules.

► dna

· It replicates itself, making two DNA molecules where before there was one; and it makes protein.· After all, the DNA molecule is one continuous chain of bases, and without punctuation, the code would be nonsensical.· We have seen that DNA molecules are the centre of a spectacular information technology.· In fact, only about five per cent of each DNA molecule actually provides any meaningful code.· In cell division the spiral appears, as well as in the DNA molecule in the cell nucleus.· The messages that DNA molecules contain are all but eternal when seen against the time scale of individual lifetimes.· These four bases provide the only source of variation in the DNA molecule.

► protein

· They are smaller molecules than proteins, so they have to become attached to a protein molecule before they are activated.· One experiment produced crystals of protein molecules that drug company researchers believe could advance the development of antiviral drugs.· These slightly altered protein molecules are mass-produced by the protein-making machines inside the developing brain cells.· The antibodies are protein molecules that can fit on to an allergen and inactivate it.· Some protein molecules are simply too large for microbes to handle.· Research has however shown that in terms of the arrangement of the protein molecules this model is no longer accurate.· Synthesizing any new protein molecule from scratch takes a matter of minutes.· Sometimes, different protein molecules will fit together, like the pieces of a three-dimensional jigsaw, to form larger-scale structures.
