Heptose
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 (ketoheptoses).
Examples
There are few examples of seven-carbon sugars in nature, among which are:
- sedoheptulose or D-altro-heptulose (a ketose), an intermediate in the Calvin cycle and in lipid A biosynthesis
- mannoheptulose, found in avocadoes
- L-glycero-D-manno-heptose (an aldose), a late intermediate in lipid A biosynthesis.
Ketoheptoses have 4 chiral centers, whereas aldoheptoses have 5.

gollark: ubq said they would add any reasonable dependency you wanted.
gollark: Maybe even five.
