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

, phenylalanine, and aspartic acid are all chemicals, too, and they're all a natural part of what makes a banana.
In addition, valine, leucine, and isoleucine degradation, propanoate metabolism, fatty acid degradation, and butanoate
metabolism were downregulated in the intramuscular adipose tissue.
(R)-3-Hydroxybutyric acid is very important in butanoate
Hence the proposed compound which accounted for about 7% of the extract is named Poly 3-(2,4-dihydroxyphenyl) butanoate

, ethyl pentanoate, ethyl 2-methyl butanoate
, ethyl hexanoate, hexyl 3-methyl butanoate
, 3-methylbutyl acetate, and ethyl cinnamate.
The highest content of neryl butanoate
(13.9%) and compounds with curcumene structure (11.3%) was identified in the sample from France.
* Four esters were selected to explore the structural diversity of this functional group: methyl acetate, ethyl acetate, ethyl butanoate
, and butyl acetate.

The following analytical standards were purchased from Sigma-Aldrich (Germany): ethyl butanoate
, ethyl crotonate, butyl acetate, butyl butanoate

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.
