Studies on Structure and Properties of Water Soluble Polysaccharide from Fruiting Body of Cordyceps Militarvs(L.) Link
Bibliographic record
Abstract
A water soluble crude polysaccharide has been isolated from the fruiting body of cultivated Cordyceps militarvs(L.) Link. The GC analysis indicated that it contained the monosaccharides of Gal, Man, Glc and GlcA. Their molar ratio is 1 00∶1 58∶7 89∶0 19. The crude polysaccharide was fractionated with ethanol to get three fractions, which were CM Ⅰ, CM Ⅱ and CM Ⅲ. CM Ⅱ was further purified to get one homogeneous fraction named CMB. The molecular weight was estimated to be 60000 by means of gel filtration. CMB is a greyish white powder. The GC analysis indicated that it was composed of Gal, Man, Glc and the molar ratio is 1 00∶1 38∶5 10. Partial hydrolysis with an acid, periodate oxidation, Smith degradation, IR, GC and methylation analyses, GC/MS analyses were used for the structure analyses of CMB. The results reveal that CMB is of a lower branched structure. The main chain is composed of (1→6) linked Man, (1→6) linked Glc, (1→4) linked Glc and (1→4) linked Gal. Some of (1→4) linked Glc and all (1→4) linked Gal residues are substituted at 3 O and 6 O respectively. (1→4) Linked Glc residues without branch probably exist with other monosaccharides alternately. On an average, there is one branch every ten hexose residues. The side chain is composed of major (1→4) linked Glc and minor (1→6) linked Glc. The nonreduced end is composed of Gal and Glc. The main glycosidic link of CMB is α configuration.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
