Odor activity calculations showed that ethyl butanoate
, ethyl hexanoate and ethyl octanoate were primarily responsible for the fruity, sweet aroma.

This enzyme participates in 10 metabolic pathways: fatty acid metabolism, synthesis and degradation of ketone bodies, valine, leucine and isoleucine degradation, lysine degradation, tryptophan metabolism, pyruvate metabolism, benzoate degradation via coa ligation, propanoate metabolism, butanoate
metabolism, and two-component system general.
, phenylalanine, and aspartic acid are all chemicals, too, and they're all a natural part of what makes a banana.
Hence the proposed compound which accounted for about 7% of the extract is named Poly 3-(2,4-dihydroxyphenyl) butanoate
, ethyl butanoate
, ethyl pentanoate, ethyl 2-methyl butanoate
, ethyl hexanoate, hexyl 3-methyl butanoate
, 3-methylbutyl acetate, and ethyl cinnamate.
Among the esters identified in both extraction techniques, ethyl butanoate
, ethyl hexanoate, (3z)-3-hexenyl acetate, hexyl acetate, hexyl butanoate
and hexyl hexanoate were the major ones.
The signals of methynic carbons at [delta] 95 (C-18) and 97 (C-19) indicate the existence of the diacetalic ring system C, while those at [delta] 170-174 suggest the presence of acetate and butanoate
groups as substituents.
