The K24 antigen has the repeating unit----7)-alpha-Kdop-(2----1)-Gro-(3-P. In the polymer, 56% of the repeating units are O-acetylated at C-4 of Kdo, approximately 28% at C-5 of Kdo, and approximately 16% are not acetylated.","tracks":[{"project":"sentences","denotations":[{"id":"TextSentencer_T1","span":{"begin":0,"end":112},"obj":"Sentence"},{"id":"TextSentencer_T2","span":{"begin":113,"end":414},"obj":"Sentence"},{"id":"TextSentencer_T3","span":{"begin":415,"end":489},"obj":"Sentence"},{"id":"TextSentencer_T4","span":{"begin":490,"end":639},"obj":"Sentence"},{"id":"T1","span":{"begin":0,"end":112},"obj":"Sentence"},{"id":"T2","span":{"begin":113,"end":414},"obj":"Sentence"},{"id":"T3","span":{"begin":415,"end":489},"obj":"Sentence"},{"id":"T4","span":{"begin":490,"end":639},"obj":"Sentence"}],"namespaces":[{"prefix":"_base","uri":"http://pubannotation.org/ontology/tao.owl#"}],"attributes":[{"subj":"TextSentencer_T1","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T2","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T3","pred":"source","obj":"sentences"},{"subj":"TextSentencer_T4","pred":"source","obj":"sentences"},{"subj":"T1","pred":"source","obj":"sentences"},{"subj":"T2","pred":"source","obj":"sentences"},{"subj":"T3","pred":"source","obj":"sentences"},{"subj":"T4","pred":"source","obj":"sentences"}]},{"project":"NCBITAXON","denotations":[{"id":"T1","span":{"begin":32,"end":39},"obj":"OrganismTaxon"},{"id":"T2","span":{"begin":149,"end":165},"obj":"OrganismTaxon"}],"attributes":[{"id":"A1","pred":"db_id","subj":"T1","obj":"562"},{"id":"A2","pred":"db_id","subj":"T2","obj":"562"},{"subj":"T1","pred":"source","obj":"NCBITAXON"},{"subj":"T2","pred":"source","obj":"NCBITAXON"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"sentences","color":"#93dcec","default":true},{"id":"NCBITAXON","color":"#ece293"}]}]}}
