We live in a protein-obsessed society. With good reason, protein is a powerful macronutrient. It’s a component in every cell in the body and your hair, skin and nails are made of protein. It’s used to construct and repair tissues, build strong bones and muscles and make enzymes, hormones and other chemicals. A protein molecule is a nitrogenous organic compound consisting of long chains of linked building blocks called “amino acids."
