Lyksoosi (C5H10O5) on monosakkaridiyhdiste, joka kuuluu aldopentooseihin, hemiselluloosiin ja hiilihydraatteihin. Lyksoosi sisältää viisi hiiliatomia, mikä tekee siitä pentoosin, ja aldehydiryhmän. Lyksoosilla on D- ja L-stereoisomeerit, joista vain D-muotoa esiintyy luonnossa.

Lyksoosi on ksyloosin C'-2 -hiiliepimeeri. Se on luonnossa harvinainen. Sitä tavataan esim. bakteerien glykolipidien osana.[1]
