About 20% of human subjects are specifically anosmic to the odor of the heterocyclic Schiff's base 1-pyrroline. Odor threshold measurements on 33 nitrogenous bases were made with panels of specific anosmics and normal observers. The anosmia proved to be very selective, and was encountered only with 1-pyrroline and its homolog 1-piperideine. The odor of 1-pyrroline resembles very closely that of human semen, and possibly represents a vestigial pheromone. It is suggested that this specific… Expand
Specific anosmia to trimethylamine: The fishy primary odor
About 7% of human subjects are specifically anosmic to the odor of trimethylamine. Odor threshold measurements on 16 aliphatic amines were made with panels of specific anosmics and normal observers.Expand
Excretion and Perception of a Characteristic Odor in Urine after Asparagus Ingestion: a Psychophysical and Genetic Study
TLDR
It is concluded that individual differences exist in both odorant production and odor perception, and the biological basis for the inability to produce the metabolite in detectable quantities is unknown. Expand
On the chemistry of 1-pyrroline in solution and in the gas phase
TLDR
The results indicate that in solution the volatility of the monomer species is significantly higher than that of the trimer species, and 1-pyrroline is evaporated mainly in its monomer state. Expand
Sensitivity to allyl isothiocyanate, dimethyl trisulfide, sinigrin, and cooked cauliflower consumption
The consumption of cauliflower consumers has been related to the olfactory and gustatory sensitivities to potentially objectionable flavor compounds in this vegetable. Based on the ascendingExpand
Deciphering the chemical origin of the semen-like floral scents in three angiosperm plants.
TLDR
Comparison of the results to earlier studies indicate that compared to the traditional GC-MS approach the direct corona discharge ionization mass spectrometry provides more sensitive detection of VOCs with high proton affinity, in particular volatile amines, and therefore can be used to complement traditional GC -MS approach for the highest chemical coverage of V OC analysis.

Smells like debauchery: The chemical composition of semen-like, sweat-like and faintly foetid floral odours in Xysmalobium (Apocynaceae: Asclepiadoideae)
TLDR
This work used dynamic headspace extraction methods and coupled gas chromatography-mass spectrometry (GC–MS) to examine the scent chemistry of three unusually scented asclepiads in the genus Xysmalobium and then combined these data with previously published data to explore inter- and intraspecific variation in this genus.

Mexican Fruit Fly Attractants: Effects of 1-Pyrroline and Other Amines on Attractiveness of a Mixture of Ammonia, Methylamine, and Putrescine
Several amines were tested alone and in combination with AMPu, an attractant mixture containing ammonium bicarbonate or ammonium carbonate, methylamine hydrochloride, and putrescine, forExpand

TLDR
It is reported that a subject’s response to the bitter chemical 6-n-propylthiouracil (PROP) is less predictive of overall taste intensity ratings than ratings of sucrose, sodium chloride, and citric acid. Expand
Early release of 1-pyrroline by Pseudomonas aeruginosa cultures discovered using ambient corona discharge ionization mass spectrometry
Pseudomonas aeruginosa (PA) is a leading cause of nosocomial infections in humans with an increasing number of health-threatening implications, which urges faster clinical detection of this pathogen.Expand
Lactic fermentation to improve the aroma of protein extracts of sweet lupin (Lupinus angustifolius).
TLDR
The aroma profile of untreated LPE was compared to those of fermented protein extracts (LPEF) and the most powerful odourants were identified according to their mass spectra, odour descriptions, and retention indices. Expand

1‐Pyrroline: The Odor Component of Strecker‐Degraded Proline and Ornithine
SUMMARY The odor component of proline and ornithine degraded by periodate, isatin, or ninhydrin was identified as 1-pyrroline by means of gas chromatography on three columns, mass spectra, andExpand
Measurement of Specific Anosmia
TLDR
The objective of this work was to measure the quantitative deficiency of the specific anosmics, in comparison with normal Ss with respect to each odorant, for the definition of what is believed to be one of the “primary odors” of the sense of smell, the "sweaty" primary epitomized by isovaleric acid.

Specific Anosmia: a Clue to the Olfactory Code
TLDR
The fact that some people cannot detect the odour of isobutyric acid even though their sense of smell may be otherwise complete suggests that this substance, or a substance with molecules which are similar in size, shape and functional group, may represent a primary odour. Expand
ROLE OF POLYAMINES IN REPRODUCTIVE PHYSIOLOGY AND SEX HORMONE ACTION *
TLDR
This article attempts to tie together some facts regarding the role of spermidine and spermine, and their biosynthetic precursor putrescine, in a number of disparate processes related to reproduction in mammals and suggests some thoughts as to their possible functional significance. Expand
Odour-Blindness to Musk: Simple Recessive Inheritance
THREE types of odour-blindness or specific anosmia have been studied, but genetical evidence so far obtained is tentative or inconsistent1. The rare anosmia to the n-butylmercaptan of skunk2, andExpand
Odour-Blindness to Musk: Simple Recessive Inheritance
TLDR
Specific anosmia in humans to two substances, iso-valeric acid and a musk, and a difference of incidence in both anosmias between Black and Caucasian subjects is found. Expand
