Amino acids and nitrogenous compounds are fundamental building blocks of life. Amino acids serve as the building blocks of proteins, crucial for various biological processes. They include essential and non-essential types, with essential amino acids needing to be obtained from the diet. Nitrogenous compounds like nucleotides are essential for DNA and RNA structure, while other compounds, such as urea, play key roles in waste elimination. Together, amino acids and nitrogenous compounds are vital for the structure and function of living organisms.
