Q1. What are Protein? Give its functions and digestion in detail.
- Proteins are macronutrients composed of amino acids linked by peptide bonds.
- Functions include tissue growth, repair, maintenance, enzyme action, and hormone regulation.
- Proteins are vital for nutrient transport, immune function, and fluid balance.
- Digestion starts in the stomach with HCl and pepsin breaking proteins into polypeptides.
Answer: Proteins are complex organic compounds that are fundamental macronutrients, essential for life. They are composed of smaller units called amino acids, which are linked together by peptide bonds to form long chains. These chains then fold into specific three-dimensional structures, crucial for their diverse biological functions. Proteins perform numerous critical functions within the human body. They are vital for the growth, repair, and maintenance of all body tissues, including muscles, skin, ...
