Answer:
Proteins are the building blocks of life. Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids.
Step-by-step explanation:
Your body needs protein to stay healthy and work the way it should. Protein is also a critical part of the processes that fuel your energy and carry oxygen throughout your body in your blood.
Amino acids are required for the synthesis of body protein and other important nitrogen-containing compounds, such as creatine, peptide hormones, and some neurotransmitters. Although allowances are expressed as protein, the biological requirement is for amino acids.
