Protein is the building blocks of life (nlm.nih.gov). Amino Acids are the building block of protein. Amino acids bond together to make long chains, which is protein (nlm.nih.gov). Human body uses amino acids to make proteins to help the body break down food, repair body tissue, grow, and perform many other body functions (nlm.nih.gov). Amino acids can also used as a source of energy by the body (nlm.nih.gov). According to what I learned in Bioorganic lecture, the amino acid structure contains a carboxylic acid group (-COOH) and an amino group (-NH2) bonded to the carbon atom. The scientists have discovered over 50 amino acids, however, only 20 are used to make proteins in the human body (nlm.nih.gov). Of those 20 amino acids, 9 are defined as essential, meaning that the human body cannot synthesize it, hence must be come from other source (food). The other 11 amino acids can synthesize by an adult body (nlm.nih.gov). The amino acids that we used in this experiment were phenylalanine, leucine, lysine, and alanine. They are not flammable, however propanol and acetic acid can pose health risks or flammable. The ninhydrin can stain your skin purple all day if you don’t wear gloves when using it. Phenylalanine was one of the amino acid that used in the lab. It falls under the essential amino acid group. There are 3 forms of phenylalanine: D-phenylalanine, L-phenylalanine, DL-phenylalanine (m.webmd.com). Meat, fish, cheese, milk, and eggs are the major dietary sources of…
