Study Notes
Compounds and Classifications
- Carbohydrates include monosaccharides, oligosaccharides, and polysaccharides.
- The molecular formula of glucose is C₆H₁₂O₆.
- Reducing sugars are classified as those that can donate electrons or reduce other molecules; they include all monosaccharides and some disaccharides.
Sugars and Non-Sugars
- The main difference between sugars and non-sugars lies in their structure; sugars are sweet-tasting and soluble in water, while non-sugars are typically tasteless and may not dissolve.
- Glucose can be prepared through various methods such as photosynthesis, hydrolysis of starch, or via chemical synthesis from non-carbohydrate precursors.
Types of Carbohydrates
- Monosaccharides like glucose and fructose belong to the group of simple carbohydrates known as sugars.
- Reducing sugars, such as glucose and fructose, respond positively to Tollens’ and Fehling's solution tests, which help identify their reducing capabilities.
Reducing vs. Non-Reducing Sugars
- The main difference between reducing sugars and non-reducing sugars is that reducing sugars have free aldehyde or ketone groups capable of reducing agents, while non-reducing sugars do not.
Special Preparation Methods
- A compound formed by boiling sucrose with dilute HCl or dilute H₂SO₄ in an alcoholic solution, or through hydrolysis of starch with dilute H₂SO₄ at 393 K under pressure, is glucose.
Classification of Non-Sugars
- Non-sugars, including tasteless and amorphous compounds, are water-insoluble and do not exhibit sweet flavors, typically found in polysaccharides.
