Molecular Structures and Biochemical Physiology of the Proteins Involved in Chemical Communications in Some Insect Species

The olfactory systems of terrestial animals are designed to trap and sample volatile hydrophobic molecules. Some of these molecules are odorants, such as volatile plant compounds and pheromonesemitted from the other organisms. Insect antennae have a primary function of detecting odors including sex...
