1. PROTEINS Von: Lorenz, Alex GV, Armin und Max

2. Contents Proteins and their function in our bodies Protein dosages Connection between proteins and amino acids Essential amino acids Foods with a high protein content

3. Proteins and their function in our body Antibodies: defends our body from foreign invaders Contractile proteins (Actin, Myosin): responsible for movement in muscles Enzymes: facilitate biochemical reactions Protein hormones: coordinate certain body activities Structural proteins: (e.g. keratin, collagen) Transportation proteins: hemoglobin (oxygen) Dietary benefits: Repairs tissue Energy source Better movement function

5. Connection between proteins and amino acids Amino acids are the building blocks of proteins -> Proteins are made up of many amino acids linked to each other like a chain There are 20 different amino acids that our proteins are built out of The length of an amino acid chain a protein is made of can vary from just a few up to hundred or thousands of amino acids The sequence in which the different amino acids are linked together is central to the structure and function of a protein

6. Essential amino acids Some amino acids can not be produced by the body itself but have to be taken in through our food There are 9 amino acids humans can’t produce: 1. Phenylalanine 2. Valine 3. Threonine 4. Tryptophan 5. Methionine 6. Luecine 7. Isoleucine 8. Lysine 9. Histidine

7. Foods with a high protein content Fish Chicken Red meat Milk Yoghurt Cottage Cheese Eggs Beans Nuts
