Intro says "...although 9-carbon sugars do not occur naturally..." but they do, and commonly. The nonuloses, or sialic acids, are incredibly abundant in all higher life and are critical for everything from brain development to immune system function. This one on this page, Neuraminic acid, may not be natural, but a lot of its derivatives are like /info/en/?search=N-Acetylneuraminic_acid which is just the acetylated form of it (and is one of the most critical and common nonuloses found in mammals.) 162.220.42.222 ( talk) 23:14, 17 February 2022 (UTC) reply
