Sugar solutions soft drinks (a, b) 3- using your findings in this experiment, estimate the amount of sugar you take from soft drinks in a day reference.

Abstract: a very simple and direct radioactive isotope method has been described for the quantitative determination of reducing sugars the method can be adapted to give any degree of sensitivity desired. The nelson-somogyi method is one of the classical and widely used methods for the quantitative determination of reducing sugars principle the reducing sugars when heated with alkaline copper tartrate reduce the copper from the cupric to cuprous state and thus cuprous oxide is formed. Depending on the concentration of sugars, yellow to green color is developed all monosaccharides are reducing sugars as they all have a free reactive carbonyl group some disaccharides, like maltose, have exposed carbonyl groups and are also reducing sugars, but less reactive than monosaccharides.

Quantitative estimation of some metabolites and enzymes of fig trees is often soft and the latex precludes its estimation of reducing sugar.
