Scent glands axillary

Thus, Amoore suggests that, if we have a specific olfactory receptor for a given odorant then that odorant might be naturally given off by the body. The sweaty odor of isovaleric acid is probably part of the foot odor and is produced by the action of skin bacteria on apocrine secretion (see below). Pyrolline, the spermous odor, has been shown to be produced by enzymatic breakdown of the polyamines in semen (40). Androst-16-en-3-one, the urinous primary odor, has axillary-like odor the related androstenol, which is found in urine, is perceived as a musky odor to some individuals (41). Both steroids are found in axillary sweat and may be formed as metabolites of apocrine secretion. Chemicals which fit the malty anosmia have not as yet been reported from human odor sources. The natural musks, such as cycloheptadecenone (civet), were first obtained from animal scent glands. 

Can hnmans reliably identify gender and individnals by body odors The answer to this qnestion matters very mnch in a nnmber of contexts of social and sexnal behavior snch as parent-offspring bonding, mate choice, or nepotism. A classical experiment has examined the role of the axillary odor, the most powerfnl hnman scent. This odor is the resnlt of bacterial action on the secretion of the axillary glands. These skin glands are of the apocrine type which is a modified sweat gland that prodnces an aqneons secretion.
