C6H12O6
C12H22O11
С6Н10О5

Answer 2

Glucose (C6H12O6):

Glucose is a monosaccharide, which means it is a simple sugar that cannot be broken down into smaller sugar molecules. Its chemical formula is C6H12O6 Glucose is an important source of energy for living organisms and is commonly referred to as blood sugar. It is a primary fuel for cellular respiration and is used by cells to produce ATP, the energy currency of the cell.

Chemical Properties of Glucose:

- Glucose is a colorless, crystalline solid that is soluble in water. - It has a sweet taste and is commonly used as a sweetener in food and beverages. - Glucose is a reducing sugar, meaning it can donate electrons to other molecules in chemical reactions. - It undergoes various chemical reactions, such as oxidation, reduction, and fermentation, which are important in biological processes.

Sucrose (C12H22O11):

Sucrose, commonly known as table sugar, is a disaccharide composed of glucose and fructose molecules. Its chemical formula is C12H22O11 Sucrose is obtained from sugar cane or sugar beets and is widely used as a sweetener in food and beverages.

Chemical Properties of Sucrose:

- Sucrose is a white, crystalline solid that is soluble in water. - It has a sweet taste and is commonly used as a sweetener in various food products. - Sucrose is a non-reducing sugar, meaning it does not have the ability to donate electrons in chemical reactions. - It can be hydrolyzed into its constituent monosaccharides, glucose, and fructose, through the action of enzymes or acids.

Starch:

Starch is a complex carbohydrate composed of a large number of glucose molecules joined together. Its chemical formula is (C6H10O5)n, where n represents the number of glucose units Starch is the primary storage form of glucose in plants and is found in various plant-based foods.

Chemical Properties of Starch:

- Starch is a white, powdery substance that is insoluble in cold water. - It consists of two types of glucose polymers: amylose and amylopectin. - Amylose is a linear polymer of glucose units joined by α-1,4-glycosidic bonds. - Amylopectin is a branched polymer of glucose units with both α-1,4-glycosidic and α-1,6-glycosidic bonds. - Starch can be hydrolyzed into glucose molecules through the action of enzymes, such as amylase.

Please note that the chemical properties mentioned above are general characteristics of glucose, sucrose, and starch. There may be additional specific properties and reactions associated with these compounds depending on the context and conditions of the reactions.
