DATABASE_MATCH
via local kg-microbe CHEBI transform
Local CHEBI labels CHEBI:134431 as acetyl xylan and lists acetylated xylan as an exact synonym.
DATABASE_MATCH
via MIM curation (#322)
mapping_quality EXACT_MATCH -> SYNONYM_MATCH. CHEBI:134431 carries no structural definition, so it is a class rather than an individual, and the record's label 'Acetylated xylan' does not equal the term label 'acetyl xylan'. EXACT_MATCH therefore asserted an identity the pair does not have. Re-graded because naming variant of the same substance.
