How are proteins made? Proteins are made from chemical building blocks called amino acids. Amino acids are all different, just like letters of the alphabet are different. Many letters = many words Many amino acids = many proteins Proteins form body organs, brain cells, bones, etc. Example: Hemoglobin is the protein in red blood cells that carries oxygen to every cell in the body.
8
Complete & Incomplete Proteins Proteins are made from amino acids There are 22 amino acids 9 are essential The human body produces the rest as needed. Complete proteins contain all 9 essential amino acids Found in animal sources (soy products and quinoa too!) Incomplete proteins are missing one or more essential amino acids Found in plant sources
9
Complimentary Proteins Eating a combination of plant foods (incomplete proteins) in an effort to get all essential amino acid. Beans and rice Whole wheat toast and peanut butter
10
How do I digest and use protein? Protein in food is broken down during digestion in the small intestine – then transported via the bloodstream and reassembled again into whatever protein is needed: Body Repair Growth Energy
11
Why do I need it? Growth Maintenance of body systems Enzymes to help body function Hormones Antibodies to fight invaders Fluid balance Energy
