Define,classify properties and dietary sources of carbohydrates and proteins, include their role in human nutrition?

Carbohydrates are organic compounds made up of carbon, hydrogen, and oxygen. They are classified into two main categories: simple carbohydrates (sugars) and complex carbohydrates (starches and fiber). Simple carbohydrates are found in foods like fruits, honey, and milk, while complex carbohydrates are found in foods like grains, legumes, and vegetables.

Proteins are organic compounds made up of amino acids. They are classified into two main categories: complete proteins (contain all essential amino acids) and incomplete proteins (lack one or more essential amino acids). Complete proteins are found in animal products like meat, fish, and dairy, while incomplete proteins are found in plant-based foods like beans, nuts, and seeds.

Carbohydrates are the body's main source of energy, providing fuel for the brain, muscles, and other organs. They also play a role in digestion and are important for maintaining healthy blood sugar levels. Proteins are essential for building and repairing tissues, making enzymes and hormones, and supporting the immune system. They also provide a source of energy when carbohydrates are not available.

Some dietary sources of carbohydrates include fruits, vegetables, whole grains, and legumes. Some dietary sources of proteins include meat, fish, dairy, beans, nuts, and seeds. It is important to include a variety of carbohydrates and proteins in the diet to ensure adequate intake of essential nutrients and support overall health and well-being.
