Help students or lab technicians record, validate, and interpret Molisch test results for carbohydrate samples, reducing common errors in color interpretation and result logging.
Uji Molisch positif untuk semua sampel karbohidrat, baik monosakarida, disakarida, maupun polisakarida. Kontrol negatif akuades tidak bereaksi. Cincin ungu terjadi karena kondensasi antara α-naftol dan furfural (dari dehidrasi karbohidrat). jurnal+uji+molisch+karbohidrat+patched
The Molisch test is based on the dehydration of sugar molecules to form furfural derivatives when carbohydrates are heated in the presence of a concentrated acid (usually sulfuric acid or hydrochloric acid). These furfural derivatives then react with α-naphthol (or another phenolic compound) present in the Molisch reagent to form a purple-colored compound. This color change is indicative of a positive test for carbohydrates. Help students or lab technicians record, validate, and
💡 : Uji Molisch sangat sensitif. Serat kapas (selulosa) atau debu dari udara yang jatuh ke dalam tabung reaksi bisa menyebabkan hasil "positif palsu" karena mengandung karbohidrat. Cincin ungu terjadi karena kondensasi antara α-naftol dan
