L -streptose is a monosaccharide from streptomycetes and part of the antibiotic streptomycin .

properties

The structure of L- streptosis is similar to apiose . Strictly speaking , L -streptose is not a carbohydrate due to its molecular formula . It has two aldehyde groups . The biosynthesis in Streptomycetes takes place from glucose . L -streptose can be produced synthetically using protective groups from other monosaccharides.
