1) The insect odorant receptors, as other odorant receptors from nematoid to human, have long been perceived to be G-protein-coupled receptors(GPCR).

2) In this paper, the gene of general odorant binding protein 2 in the antenna of Helicoverpa assulta (Guen?)was cloned and expressed in Escherichia coli.

3) Before it tunnels, the electron distorts the odorant molecule's electrical field.

4) To test his theory, he went into the laboratory with a few auklet feathers. An analysis showed him the chemicals that make up the auklet's "odorant."

5) Theoretically, every known odorant molecule could have an agreed descriptor.

6) Yet here's a twist: odorant molecules typically contain many hydrogen atoms.

7) In the fruit fly, the best-studied odor detectors, odorant receptors, are found on only about 70 percent of olfactory neurons.

8) Tetrahydrothiophene is the preferred Odorant in city gas. It is being used widely in market with the success of West-to-East Gas Project.

9) With the odorant genes in hand, Dr. Bargmann could apply genetics to figuring out how the worm's sense of smell worked.

10) A olfactory cell can express one odorant receptor. There are about 350 odorant receptor genes in human.

11) E-nose system is a kind of instrument which is composed of selective chemical sensors array and appropriate pattern recognition system to detect and classify simple or complex odorant.

12) Pheromone binding proteins (PBPs) in insects are one branch of multigene family of odorant binding proteins (OBPs) and play an important role in the recognition of sex pheromone.

13) Therefore, a 12-item odor identification test, termed the Cross-Cultural Smell Identification Test (CC-SIT), which incorporates multicultural odorant items was developed.

14) Food offered at TMSK Peony 66 contains no artificial odorant such as monosodium glutamate, essence of chicken and mushroom but fresh soup.

15) An engineered egg is placed in a voltage clamp system and an odorant is dissolved in the buffer solution in which the egg is floating.

16) This paper introduces an apparatus blowing adsorption and an experiment method for sampling and analyzing the volatile odorant of plant.

17) In some cases, the researchers found that a single odorant triggers several receptors while in other cases receptors are specifically tuned to unique compounds.

18) As a result, the surface of the egg is covered with the mosquito odorant receptors.

19) These receptors are located on the olfactory neuron in the nasal epithelium and to detect different odorant molecules.

20) The olfactory behavior of insects is very complicated and involves many kinds of proteins, namely, odorant-binding proteins,(http:///odorant.html) odorant degrading enzymes and odor receptors etc.

21) The C. elegans genome had just been decoded, and Dr. Bargmann was able to identify the worm's odorant receptor genes.

22) Odorant binding proteins are thought to play an important role in insect for perceiving odorant molecule.
