Detailed explanation-1: -Proteins are made up of chemical ‘building blocks’ called amino acids. Your body uses amino acids to build and repair muscles and bones and to make hormones and enzymes. They can also be used as an energy source.
Detailed explanation-2: -How is protein used? The body breaks down consumed protein into amino acids, and absorbs it. It is used to build muscles and organs, to make hormones and antibodies, to be stored as fat, and to be burned as energy.
Detailed explanation-3: -All cells are made mainly from protein. This means that your body needs protein to make new cells when you grow, and to replace old or damaged cells. Proteins are compounds made up of amino acid molecules. In digestion, protein molecules break down long chains of amino acids (peptides), to single amino acids.
Detailed explanation-4: -Protein is the major structural component of cells and is responsible for the building and repair of body tissues. Protein is broken down into amino acids, which are building blocks of protein.
Detailed explanation-5: -Abstract. Dietary protein is required to promote growth, repair damaged cells and tissue, synthesize hormones, and for a variety of metabolic activities.
