Zimbwawe and Kwashiorkor• We’re going to read an article as a class about Kwashiorkor

pronounced (qua-she-a-kor).• Kwashiorkor is from the Ga language of coastal Ghana and

translated means “the sickness the baby gets when the new baby comes.”

Proteins and amino acids

•Proteins are made of amino acids.• There are many different proteins in

our body and they have different functions.• The order of amino acids determines

the type of protein and its function.

Proteins and amino acids

•There are 20 amino acids and over 200,000 proteins.•How does this work?

• IE: How many different words can you make using the letters “A, T, S, N, D, E”

Building a protein

•We’re going to be making a protein using different amino acids.•Clearly this is figurative.• You’ll need to be on your best

behavior and please be careful.
