WHAT IS A PROTEIN? All proteins are made of amino acids in different orders and combinations.
They are one of the four basic molecules of life.
(Can you remember the other ones? Lipids. Carbohydrates and Nucleic Acids.) Our DNA contains the code for the proteins in our cells.
Look more deeply into proteins. There are 20 some amino acids.
Which amino acids are placed where determines its structure, ...which in turn determines its function!
