Biochemistry is the branch of science that explores the chemical processes and substances that occur within living organisms. It focuses on the structure, function, and interactions of biological molecules, such as proteins, carbohydrates, lipids, and nucleic acids, which are essential for life. Biomolecules are organic molecules that are essential for the structure, function, and regulation of living organisms. They include carbohydrates, lipids, proteins, and nucleic acids, which are the building blocks of life. Each biomolecule has a specific role in the body: Carbohydrates: Carbohydrates are sugars and starches that provide energy to the body. They are found in foods like bread, rice, and pasta. Lipids: Lipids are fats that are essential for cell structure and function. They also serve as a source of energy and help in the absorption of vitamins. Proteins: Proteins are large molecules made up of amino acids. They play a crucial role in cell structure, function, and regulation. They are also involved in the immune system, enzymes, and hormones. Nucleic Acids: Nucleic acids, such as DNA and RNA, are responsible for storing and transmitting genetic information. They are essential for cell growth, division, and function. Understanding biochemistry and biomolecules is crucial for understanding how living organisms function and how diseases can arise when these processes are disrupted.
