heptoses A heptose is a monosaccharide with seven carbon atoms. They have either an aldehyde functional group in position 1 (aldoheptoses) or a ketone functional group in position 2, 3 or 4 (ketoheptoses). Ketoheptoses have 4 chiral centers, whereas aldoh ...

found in nature, and is found in various fruits and vegetables ranging from carrots and leeks to figs, mangos and avocados. It is an intermediate in respiratory and photosynthetic pathways and plays a vital role in the non-oxidative branch of the pentose phosphate pathway. Studies have shown that 7-O-galloyl-D-sedoheptulose, a chemical extracted from dogwood fruit, is able to reduce pro-inflammatory markers '' in vivo'' such as interleukin-6 (IL-6) and C-reactive protein and thus might be able reduce low-level inflammation in humans. While this compound contains a sedoheptulose moiety, sedoheptulose itself has not been shown to possess the same properties.
