3. EXAMPLE OF FOOD RICH IN CARBOHYDRATE

4. WHAT are CARBOHYDRATES?
• Carbohydrates, or carbs, are sugar molecules. Along with proteins and
fats, carbohydrates are one of 6 main essential nutrients found in foods
and drinks.
• are a type of macronutrient found in certain foods and drinks. Sugars,
starches and fiber are carbohydrates.

5. The three main types of carbohydrates
•1.Sugars
• Sugars are also called simple carbohydrates because they are in the most basic form. They
can be added to foods, such as the sugar in candy, desserts, processed foods, and regular
soda. They also include the kinds of sugar that are found naturally in fruits, vegetables, and
milk.

6. The three main types of carbohydrates
•2.starches
• Starches are complex carbohydrates, which are made of lots of simple sugars strung
together. Your body needs to break starches down into sugars to use them for energy.
Starches include bread, cereal, and pasta. They also include certain vegetables, like potatoes,
peas, and corn.

7. The three main types of carbohydrates
•3.Fiber
• Fiber. It is also a complex carbohydrate. Your body cannot break down most fibers, so eating foods with
fiber can help you feel full and make you less likely to overeat. Diets high in fiber have other health
benefits. They may help prevent stomach or intestinal problems, such as constipation. They may also
help lower cholesterol and blood sugar. Fiber is found in many foods that come from plants, including
fruits, vegetables, nuts, seeds, beans, and whole grains.

8. Monomers of carbohydrates
• Monomers of carbohydrates are simple sugars and the basic building blocks of
carbohydrates, they are also known as monosaccharides

9. Carbohydrates FUNCTION
• Providing energy and regulation of blood glucose
• Sparing the use of proteins for energy
• Breakdown of fatty acids and preventing ketosis
• Biological recognition processes
• Flavor and Sweeteners
• Dietary fiber

10. CARBOHYDRATES STRUCTURE
• Carbohydrates are “hydrates of carbon” and have the generic structure
of C(n)H(2n)O(n). A single sugar unit is a monosaccharide. These can consist of
3-carbon moieties (triose), 4-carbon units (tetrose), 5-carbon moieties (pentose),
and 6-carbon moieties (hexose).
