Proteins From Amino Acids Flashcards
What are two peptides called?
Two amino acids are a dipeptide. More and more amino acids form a polypeptide.
Where are polypeptides made?
Polypeptide and proteins are synthesises in cells on ribosomes - protein synthesis.
What is the function of a protein determined by?
Function of each protein is determined by its structure.
What is the structure of an amino acid determined by?
Structure of each protein is determined by its amino acid - the unique amino acid sequence of a polypeptide or protein is called its primary structure.
What do different amino acids have?
Different amino acids have different properties - so sequence of amino acids effects properties.
How many different possibilities are there for a four long amino acid chain?
A four amino acid long chain has 20X20X20X20 possibilities of difference = 160000.
How can proteins be broken down?
Formation/break down of peptide bonds is catalysed by enzymes. Protease catalyses break down of peptide.
