The iodine-starch test, a staple of chemistry and biology labs, has been used to detect starch since its discovery in 1814. This profound color change reveals the presence of starch and offers a glimpse into the molecular structure of this important plant carbohydrate.

Did you know that all monosaccharides, the simplest form of carbohydrates, are classified as reducing sugars? So, what is the test for reducing monosaccharides? The primary qualitative test is the Benedict's test, a colorimetric assay used widely in biology and chemistry laboratories to confirm their presence.

According to the World Health Organization, reducing free sugar intake is a public health priority. Learning how to measure the amount of sugar in a liquid is a crucial skill for health monitoring, quality control, and crafting everything from wine to kombucha.

The Seliwanoff's test is a foundational biochemical assay that distinguishes between aldose and ketose sugars, a distinction crucial for carbohydrate analysis. A positive Seliwanoff test, indicated by a deep cherry-red color, confirms the presence of a ketose or a sugar that can be hydrolyzed into one.
