Detailed explanation-1: -The generic structural formula of an amino acid is shown below: Hence, phosphorus is not found in amino acids.
Detailed explanation-2: -Amino acids do not contain phosphorus. Amino acids are made up of carbon, hydrogen, oxygen and nitrogen atoms.
Detailed explanation-3: -Answer: Proteins, carbohydrates and lipids are made from three basic molecules: carbon, hydrogen and oxygen. However, all proteins contain an element not found in carbohydrates and lipids is nitrogen.
Detailed explanation-4: -Phosphorus is also incorporated in nucleotides, sugars, proteins, and lipids.
Detailed explanation-5: -Each amino acid has the same core structure, which consists of a central carbon atom, also known as the alpha () carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and a hydrogen atom.
