1. Monosaccharides – Simple sugars like glucose and fructose which are the building blocks of carbs.

2. Disaccharides – Made of two monosaccharides like sucrose (table sugar) and lactose (milk sugar).

3. Polysaccharides – Long chains of monosaccharides like starch (energy storage in plants) and glycogen (energy storage in animals).

Carbohydrates is a sugar molecule and a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms.

Disaccharides are formed when two monosaccharides combine, such as sucrose and lactose.

Polysaccharides are complex carbohydrates made of long chains of monosaccharides, like starch and cellulose.

Monosaccharides are the simplest form of carbohydrates, consisting of just one sugar molecule. They are easy for the body to absorb and use as a quick source of energy. The most common monosaccharides include glucose, which is the primary energy source for cells, fructose, which is found in fruits, and galactose, which is present in dairy products and because they are simple sugars, monosaccharides provide immediate energy but may cause a rapid spike in blood sugar levels.

Disaccharides (Double Sugars)

These are formed when two monosaccharide molecules bond together. These sugars still provide energy but need to be broken down by the body into single sugars before they can be absorbed. Common disaccharides include sucrose (table sugar), lactose (milk sugar), and maltose (found in grains).

Polysaccharides (Complex Carbohydrates)

Polysaccharides are made up of long chains of sugar molecules. Because of their complex structure, they take longer to break down, providing a steady and sustained source of energy. Examples of polysaccharides include starch which is found in foods like potatoes and rice, glycogen that is stored in the liver and muscles as a backup energy source, and cellulose, a form of fiber that helps with digestion but isn’t broken down for energy. Complex carbohydrates are often found in whole grains, vegetables, and legumes, making them a healthy and essential part of a balanced diet.

Carbohydrates is a major source of our energy. It involves in fat and protein synthesis. It also had the formula C(H2O)n

• Disaccharides: These carbohydrates are formed when two monosaccharides combine. Common examples include sucrose (table sugar), lactose (milk sugar), and maltose (malt sugar).

• Polysaccharides: These are complex carbohydrates made up of long chains of monosaccharides. They are often referred to as complex carbs. Examples include starch, glycogen, and fiber.

2. Disaccharides – Two sugar units sucrose, lactose that need to be broken down before use.

3. Polysaccharides – Long chains of sugars starch, glycogen, fiber that give long-lasting energy and support digestion.

1. Monosaccharides: These are the simplest form of carbohydrates, made up of one sugar molecule. Examples: glucose, fructose, and galactose.

2. Disaccharides: These are formed by two monosaccharides linked together. Examples: sucrose (table sugar), lactose (milk sugar), and maltose.

3. Polysaccharides: These are complex carbohydrates made up of many sugar molecules linked together. Examples: starch (in plants) and glycogen (in animals).

1. Energy Source – They provide quick energy for the body (like glucose).

2. Energy Storage – They are stored as glycogen in animals and starch in plants for later use.

3. Structural Support – They help build cell walls in plants (cellulose) and exoskeletons in insects (chitin).

• Examples: Glucose (blood sugar), Fructose (fruit sugar), Galactose (milk sugar).

2. Disaccharides (Double Sugars) – Formed when two monosaccharides combine. They must be broken down into monosaccharides before the body can use them.

• Examples: Sucrose (table sugar = glucose + fructose), Lactose (milk sugar = glucose + galactose), Maltose (malt sugar = glucose + glucose).

3. Polysaccharides (Complex Carbohydrates) – Made up of multiple sugar molecules linked together. They provide long-lasting energy and are found in starchy foods and fiber.

• Examples: Starch (in grains and potatoes), Glycogen (stored energy in the liver and muscles), Cellulose (dietary fiber from plants, aids digestion).

Disaccharides are formed by two linked monosaccharides, such as sucrose, requiring breakdown for energy use. Polysaccharides are complex chains of many sugars, like starch, providing sustained energy or structural support.

.

Polysaccharides are complex carbohydrates made of long chains of monosaccharides.

Disaccharides are composed of two monosaccharide molecules linked together.

Polysaccharides are complex carbohydrates made up of long chains of monosaccharide molecules.

• Monosaccharides are the simplest form of carbohydrates and consist of single sugar molecules. They are the building blocks of more complex carbohydrates. Disaccharides:

• Disaccharides are formed by the combination of two monosaccharides through a glycosidic bond. Polysaccharides:

  • Polysaccharides are complex carbohydrates composed of long chains of monosaccharide units linked together.

2. Disaccharides: Disaccharides are made up of two monosaccharide molecules joined together. They can be easily broken down into their individual sugars during digestion. Examples include sucrose (table sugar) and lactose (the sugar in milk).

3. Polysaccharides: Polysaccharides are complex carbohydrates made up of long chains of monosaccharides. They serve as energy storage or structural support in plants and animals. Examples include starch (found in foods like potatoes), glycogen (stored in animal tissues), and cellulose (which makes up the cell walls of plants).

These are the simplest form of carbohydrates, also known as simple sugars, and cannot be broken down into smaller sugar units. Examples include glucose, fructose, and galactose.

Disaccharides:

These are formed when two monosaccharides are linked together. Common examples include sucrose (table sugar), lactose (milk sugar), and maltose.

Polysaccharides:

These are complex carbohydrates composed of many monosaccharide units linked together. Examples include starch (found in plants), glycogen (found in animals), and cellulose (found in plant cell walls).

2. Energy Storage – Excess carbohydrates are stored as glycogen in animals and starch in plants for later use.

3. Structural Support – Some carbohydrates, like cellulose in plants and chitin in insects, help build strong structures.

2. Energy Storage – Stored as glycogen in animals and starch in plants for later use.

3. Structural Support – Form structures like cellulose in plants and chitin in insects.

Disaccharides: Two sugar units, like sucrose, broken down into monosaccharides for energy.

Polysaccharides: Long chains of sugar units, like starch and glycogen, used for energy storage.

Energy: Glucose fuels cells.

Storage: Glycogen/starch stores energy.

Structure: Cellulose/chitin builds cell walls and exoskeletons.

Biological Molecules: They're part of DNA, RNA, and glycoproteins.

Digestion: Fiber aids digestive health and blood sugar control.

Polysaccharides complex carbohydrates or multiple sugars

Polysaccharide-are large complex carbohydrates composed of many monosaccharides units like together.

2. Disaccharides (Double Sugars) – These are made of two monosaccharides linked together. Your body breaks them down into simple sugars for energy. Examples: sucrose (table sugar), lactose (milk sugar).

3. Polysaccharides (Complex Carbohydrates) – These are long chains of sugar molecules. They provide long-lasting energy and help with digestion. Examples: starch (in rice and potatoes), fiber (in vegetables and whole grains).

• Sucrose ( C_{12}H_{22}O_{11} ) is a double sugar (disaccharide).

• Cellulose and starch ( C_6H_{10}O_5 ) are complex carbohydrates (polysaccharides) with repeating sugar units.

Disaccharides - it is need to be broken down to into monosaccharides before the body can absorb them.

Polysaccharides - it is a complex carbohydrates made up of long chains of monosaccharide molecules.

Disaccharide's are formed when two monosaccharides are joined together through a glycosidic linkage.
