Summary
Biogenic amines like octopamine, tyramine, dopamine, and serotonin modulate insect antenna sensory functions. The antenna may operate semi-autonomously, with amines affecting it locally without systemic impact.
Area of Science:
- Neuroscience
- Entomology
- Sensory Biology
Background:
- Insect antennae are complex multisensory organs.
- Biogenic amines are known to modulate neuronal activity in insects.
Purpose of the Study:
- To investigate the role of biogenic amines in modulating insect antennal sensory modalities.
- To explore the potential for semi-autonomy within the insect antenna.
Main Methods:
- Review of existing literature on biogenic amine function in insect antennae.
- Analysis of neurotransmitter and neurohormone actions on antennal neurons and cells.
Main Results:
- Octopamine and tyramine impact olfactory neurons.
- Dopamine influences gustatory neurons.
- Serotonin acts as a neurotransmitter and neurohormone, affecting mechanosensory and accessory cells.
Conclusions:
- Biogenic amines modulate various sensory modalities in the insect antenna.
- The antenna may possess partial autonomy, with localized effects of hemolymph-borne amines.

Amines with low molecular weight are usually gaseous at room temperature, while those with high molecular weight are liquid or solids in nature. Usually, low molecular weight amines have a rotten fish-like smell. Diamines typically have a pungent smell. For instance, cadaverine and putrescine, depicted in Figure 1, are two molecules responsible for decaying tissue.

01:07Amines: Introduction
5.9K
Amines are organic derivatives of ammonia. They are formed by replacing one or more ammonia protons with alkyl or aryl groups. Depending upon the number of organyl groups bonded to nitrogen, amines are classified as primary, secondary, or tertiary. Primary amines have one organyl group attached to the nitrogen atom, while secondary and tertiary amines have two and three organyl groups attached to the nitrogen atom, respectively.

3.4K
The hybridized nitrogen atom in amines possesses a lone pair of electrons and is bound to three substituents with a bond angle of around 108°, which is less than the tetrahedral angle of 109.5°. However, the C–N–H bond angle is slightly larger at 112°, with a carbon–nitrogen bond length of 147 pm. This carbon–nitrogen bond length of of amines is longer than the carbon–oxygen bond of alcohols (143 pm) but shorter than alkanes’ carbon–carbon bond (154 pm). These aspects are...

01:10Nomenclature of Aryl and Heterocyclic Amines
3.2K
The simplest aromatic amine is phenylamine, which contains an –NH2 functionality directly attached to an aromatic ring. The name aniline is designated for this skeleton. As shown in Figure 1, the common names of the functionalized anilines involve prefixes ortho-, meta-, and para- to indicate the substitution position. Different functionalized aniline derivatives also have notable trivial names.

01:15Mass Spectrometry of Amines
5.5K
In mass spectroscopy, amines undergo fragmentation to give parent ions with odd molecule weights. This observed mass spectrum follows the nitrogen rule; a molecule with an odd number of nitrogen atoms produces a molecular ion with an odd molecular weight. Amines undergo fragmentation through α cleavage, producing nitrogen-containing cations—iminium ions—and alkyl radicals. Mass spectra of aromatic and cyclic aliphatic amines exhibit strong molecular ion peaks, but acyclic...

01:28Preparation of 1° Amines: Gabriel Synthesis
4.8K
Direct alkylation is not a suitable method for synthesizing amines because it produces polyalkylated products. Gabriel synthesis is the most preferred method to exclusively make primary amines. The method uses phthalimide, which contains a protected form of nitrogen that participates in alkylation only once to predominantly give primary amines.
Strong bases like NaOH or KOH deprotonate the phthalimide to form the corresponding anion, which acts as a nucleophile. Further, the anion attacks an...
