English term or phrase: Carbohydrate

Carbohidrate Test
1. Molisch Test
2. Benedict Test (2001 Division of Chemical Education, Inc., American Chemical Society.)
Benedict's Test for Glucose
Benedict's reagent is a solution of copper sulfate, sodium hydroxide, and tartaric acid.
Aqueous glucose is mixed with Benedict's reagent and heated. The reaction reduces the blue
copper (II) ion to form a brick red precipitate of copper (I) oxide. Because of this, glucose
is classified as a reducing sugar.
Discussion
Aqueous glucose is mixed with Benedict's reagent, a solution of copper sulfate,
sodium hydroxide, and tartaric acid. The mixture is heated. Carbohydrates which react
with Benedict's reagent to reduce the blue copper (II) ion to form a brick red precipitate
of copper (I) oxide are classified as reducing sugars.

Benedict's Test for Sucrose
Sucrose is heated with Benedict's reagent with no visible reaction.
Aqueous sucrose is mixed with Benedict's reagent. The mixture is then heated. Sucrose is
a nonreducing sugar and does not react with Benedict's reagent.
Benedict's Test for Fructose
Aqueous fructose is mixed with Benedict's reagent. The mixture is then heated. Fructose
reacts with Benedict's reagent and is classified as a reducing sugar. (Note that the portion
of the video showing the heating stops short and does not show the red precipitate, which can
be seen in the final still image.)
Clinitest Tablet is Added to Glucose
Clinitest tablets are anhydrous Benedict's reagent. When a tablet is added to a solution
of glucose, a brick-red precipitate of copper (I) oxide is produced. Clinitest tablets are
sold to monitor the levels of glucose in the urine of diabetics.
Clinistrip Test of Glucose is Demonstrated
Another clinical diagnostic technique for measuring levels of glucose in urine is Clinistrip.
One end of the plastic strip contains glucose oxidase and an organic dye. Glucose oxidase
oxidizes glucose to gluconic acid with the formation of hydrogen peroxide. The hydrogen
peroxide reacts with o-toluidine to produce a blue color. The color of the strip is related
to the amount of glucose present. This test is very specific for glucose since the glucose
oxidase enzyme does not react with many other compounds (including some drugs) that are readily
oxidized and give positive Benedict's tests.
