39Glucose analysis includes enzymatic and non enzymatic methods. NON- ENZYMATIC METHODS includes. :
1) COPPER REDUCTION METHOD wherein reducing sugars decreases the oxidation state of cupric ions to cuprous ions. Amount of cupric ions reduced to cuprous ions is [blank_start]directly[blank_end] proportional to reducing sugars present. Then, cuprous ions are quantified using the following methods a) [blank_start]Folin Wu[blank_end] b) Nelson Somgyi c) Neocuproine Method.
2) FERRIC REDUCTION METHOD also known as [blank_start]HAGEDORN JENSEN METHOD[blank_end] is a negative or inverse colorimetry. The reagent used is a hot alkaline solution of ferricyanide. Reducing sugars can reduce ferricyanide to ferrocyanide. Reduction is accompanied by disappearance of color from [blank_start]yellow[blank_end] to colorless at [blank_start]400 nm[blank_end]. Reduction in color is related to glucose concentration.
3) CONDENSATION METHOD also known as O-TOLUIDINE / [blank_start]DUBOWSKI METHOD[blank_end]. Reagents used are: O-toluidine, glacial acetic acid and 100 C heat. A positive result is a [blank_start]bluish green[blank_end] color measured at [blank_start]620-630 nm[blank_end].- ASOMOGYI METHOD
