The Biological Function Of Starch: What You Need To Know

PPT Characteristics of Starch PowerPoint Presentation ID506866


Starch is a white, tasteless, and odorless carbohydrate that is commonly found in many foods we eat, including rice, potatoes, corn, and wheat. In this article, we will discuss the biological function of starch and its importance in our body.

What is Starch?

Starch is a complex carbohydrate made up of glucose molecules. It is the primary source of energy for many organisms and is found in the form of granules in plants. Starch is made up of two types of molecules: amylose and amylopectin. Amylose is a linear chain of glucose molecules, while amylopectin is a branched chain of glucose molecules.

How is Starch Digested?

Starch is broken down into glucose molecules by the enzyme amylase, which is produced in the pancreas and salivary glands. The glucose is then transported to the liver and muscles where it is stored as glycogen or used for energy.

Importance of Starch in Our Body

Starch is an important source of energy for the body. It provides the necessary fuel for our brain and muscles to function properly. Starch also helps regulate blood sugar levels and can help prevent diabetes. Additionally, starch is a good source of fiber, which can help improve digestion and prevent constipation.

Starch and Weight Loss

Starch can be a part of a healthy diet and can even aid in weight loss. Foods that are high in starch, such as potatoes, rice, and pasta, can be filling and satisfying, which can help prevent overeating. Starch is also a good source of energy, which can help fuel physical activity and promote weight loss.

Starch and Athletic Performance

Starch is an important source of energy for athletes. It provides the necessary fuel for endurance and high-intensity exercise. Starch is also a good source of carbohydrates, which can help replenish glycogen stores in the muscles after exercise.

Starch and Cooking

Starch is commonly used in cooking as a thickener and stabilizer. It is often used in sauces, soups, and gravies to give them a thicker, creamier texture. Starch can also be used in baking to help bread and other baked goods rise.


In conclusion, starch is an important carbohydrate that plays a vital role in our body. It provides the necessary energy for our brain and muscles to function properly, helps regulate blood sugar levels, aids in weight loss and athletic performance, and is commonly used in cooking. By incorporating starch into our diet, we can maintain a healthy and balanced lifestyle.
