                                The human body is home to thousands of proteins, but one stands out for its sheer scale; the giant muscle protein Titin contains more than 34,000 amino acids and stretches over a micrometer in length within muscle tissue. This remarkable protein plays a crucial role in muscle elasticity, acting as a molecular spring.
