Proteins contain the elements...
carbon, hydrogen, oxygen and nitrogen
1 of 5
what is the basic unit of a protein and how many varieties of this unit are there?
amino acid, approx. 20 naturally-occurring amino acids giving rise to a huge variety of prooteins
2 of 5
what to amino acids form when they are brought together and how are they held in this way
a polypeptide (form a chain) held together by peptide bonds
3 of 5
draw the structure of the primary and secondary polypeptide
*P - straight line of amino acids *S - snake like {bc the polypeptide becomes coiled and is held together by other bonds}
4 of 5
What are the two structural possibilities of the tertiary structure of the polypeptide
The polypeptide forms sheets known as fibrous proteins, or is wound up to form a ball kno
