By Ben Harmon and Cody Lewis

Proteins are compounds that have nitrogen, carbon and hydrogen 20% of the human body contains proteins

A peptide is a compound that contains two or more amino acids Peptides have a wide range of uses in the medical and bio technological fields

They create links with amino acids residue inside the proteins

They are the building blocks of the biological process Proteins are created by amino acids bonded together by dehydration synthesis

There are about 20 different amino acid structures Some are polar Some are Nonpolar

Proteins form muscles, skin, calluses, cartilage, tissues and organs

The first level structure is the linear sequence of amino acids that makes the peptide chain In the secondary structure hydrogen bonds w/ different amino acids making a three-dimensional geometry like an alpha helix The tertiary structure creates the shape of the protein Alpha Helix is a spiral or coiled molecule

Proteins develop finger nails, hair, and fibrous proteins Allows animals to move Controls chemical reactions in living things
