Molecular Weight Of Volatile Compounds

Molecular Weight Of Volatile Compounds. Some aspergillus vocs are responsible for the characteristic musty odors associated with moldy environments while others play an important role in determining the palatability of fermented foods and drinks. 50 mg) was placed in 22 ml headspace vials, which was then capped.

A simplified scheme showing the main classes of volatile compounds from www.researchgate.net

Fungal vocs are relatively understudied compared to vocs of bacterial, plant, or synthetic origin. Empirical data on the molecular weight of a compound depends on the size of the molecule in question. Much of the research to date on fungal vocs has focus.

The molecular weight of a pure compound is determined from its chemical formula and the atomic weights of its elements. Usually, molecular structures are measured in either parts per billion (ppb), parts per million (ppm), or as micrograms per cubic meter (µg/m3) (2).
