Utility of Osazone Test to Identify Sugars
Open accessAbstract
are the most abundant organic molecules in nature. Sugars having reducing property react with phenylhydrazine hydrochloride to form characteristic osazones (crystals). These osazones can be correlated with clinical conditions like arabinose in autism, xylose in small bowel disease and galactose in galactosemia. The study aimed to evaluate utility of osazone test to identify sugars by demonstrating characteristic osazone. Study was conducted at Biochemistry department, Shri M P Shah Govt. Medical College, Jamnagar, Gujarat. We selected sugars like glucose, fructose, mannose, galactose, lactose, maltose, arabinose and xylose to demonstrate their osazone. All sugars were made available commercially. 2 grams% stock solution prepared of each sugars. Osazone test is performed for each sugar in the boiling water bath and noted down the time for appearing of crystals. Then the shape of osazone of each sugar was examined under microscope. We observed that crystals were appeared at specific interval of time during boiling and cooling slowly after boiling. We found characteristic shape of osazone of sugars under microscope. Glucose, fructose, galactose and mannose formed needle shape osazone. Maltose formed sun flower shape osazone. Lactose formed cotton-ball shape osazone. Arabinose formed dense ball needle shape osazone. Xylose formed fine but long needle shape osazone.The study demonstrated characteristic shape of osazone of sugars by performing osazone test. This simple, cheap and less time consuming test can be used to identify and differentiate sugars encountered in clinical practice.

Each contradiction between two passages listed here was confirmed by an independent check.
Rated minor: it would not touch a result — a value no result rests on, a p-value that stays on the same side of the significance level, or a conflict that is clerical, resolved elsewhere in the paper, or outside its own findings.
In the paper
§ Utility of Osazone Test to Identify Sugars > Abstract
“Glucose, fructose, galactose and mannose formed needle shape osazone.”
§ Utility of Osazone Test to Identify Sugars > LIMITATIONS
“| Galactose | Balls with thorny edge | 10 | + | ++ |”
Rated minor: it would not touch a result — a value no result rests on, a p-value that stays on the same side of the significance level, or a conflict that is clerical, resolved elsewhere in the paper, or outside its own findings.
In the paper
§ Utility of Osazone Test to Identify Sugars > DISCUSSION
“Lactose formed cotton-ball shaped crystals and maltose formed sun flower shaped crystals only after cooling slowly in present study (refer figure 5 and 6).”
§ Utility of Osazone Test to Identify Sugars > RESULTS
“Figure 7. Sun flower shaped crystals (Maltose) Figure 8. Cotton ball shaped crystals (Lactose)”

In the paper
§ Utility of Osazone Test to Identify Sugars > DISCUSSION
“We observed dense ball needle shaped and fine-long needle shaped crystals of Arabinose and xylose respectively (refer figure 7 and 8).”
§ Utility of Osazone Test to Identify Sugars > RESULTS
“Figure 6.Fine-long needle shaped crystals (Xylose) Figure 7. Sun flower shaped crystals (Maltose) Figure 8. Cotton ball shaped crystals (Lactose)”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-11, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-11 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
