Human proteins are large, complex molecules made up of amino acids, which are the building blocks of life. They play crucial roles in the body, including supporting cell structure, facilitating biochemical reactions, and regulating various biological processes. Each protein has a unique sequence of amino acids that determines its specific function. Proteins are produced through a process called protein synthesis, which involves DNA and RNA. The genetic information in DNA is transcribed into mRNA, which then guides the assembly of amino acids into proteins at the ribosome. There are thousands of different proteins in the human body, each tailored to perform specific tasks essential for health and survival.
