Study Notes
Characteristics of Carbohydrates
- Monosaccharides are sweet in taste, crystalline, and soluble in water.
Classification of Carbohydrates
- Polysaccharides include starch, cellulose, and glycogen.
Properties of Glucose
- The molecular formula of glucose is C6H12O6.
- Glucose responds to Tollens' and Fehling solution test.
Types of Carbohydrates
- Non-sugars belong to the category of polysaccharides.
- Reducing sugars fall into the category of monosaccharides.
Stereoisomers of Sugars
- A pair of stereoisomeric ring forms of any sugar differing in configuration at the anomeric carbon is called anomers.
Preparation of Glucose
- Glucose can be prepared through the hydrolysis of starch.
Optical Rotation of Sugars
- The change in the specific rotation of an optically active sugar when dissolved in water is called mutarotation.
- The proposed cyclic structure of glucose by R.D.Haworth is called the Haworth projection.
Hydrolysis of Sucrose
- The change in optical rotation that occurs during the hydrolysis of sucrose is called invert sugar formation.
Denaturation of Proteins
- The primary cause of denaturation in proteins is the disruption of hydrogen bonds.
