'''Ramnosa''' adalah gula deoksi alami. Ini dapat diklasifikasikan sebagai [[metil]]-[[pentosa]] atau 6-deoksi-[[heksosa]]. Ramnosa sebagian besar terdapat di alam dalam bentuk L-form sebagai L-ramnosa (6-deoksi-L-[[mannosa]]). Hal ini tidak biasa, karena sebagian besar gula alami berbentuk D-form. Pengecualian adalah metil pentosa L-fukosa dan L-ramnosa dan pentosa L-arabinosa. Namun, contoh D-ramnosa yang terjadi secara alami mencakup beberapa spesies bakteri seperti ''[[Pseudomonas aeruginosa]]'' dan ''[[Helicobacter pylori]]''.<ref>{{cite journal |vauthors=Melamed J, Kocev A, Torgov V, Veselovsky V, Brockhausen I | year = 2022 | title = Biosynthesis of the Pseudomonas aeruginosa common polysaccharide antigen by D‐Rhamnosyltransferases WbpX and WbpY | journal = Glycoconjugate Journal | doi = 10.1007/s10719-022-10040-4 | pmid = 35166992 | pmc = 8853325}}</ref>
