Elements of Human Nutrition Complete worksheet while watching video

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.

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

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

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

Why do I need it? Growth Maintenance of

body systems Enzymes to help

body function Hormones Antibodies to fight

invaders Fluid balance Energy

Activity 8 Essential Amino Acids

Fold your paper in to 8 sections Draw one symbol in each section, but you can’t
