How many polypeptide chains are in a protein?

There is one polypeptide chain in a single protein chain. Polypeptides refer to short protein chains - for example insulin is a 53 amino acid protein and is considered a large polypeptide. Complex multi-component [strand] protein coalescences exist - each uniquely identified component protein strand is called - of course - a subunit: two subunits is called a dimer, three subunits is called a trimer, four is a tetramer etc. A Protein is a string of Pearls {Amino Acids} of which [out of the quadrillion possible] there are ONLY Twenty Biologically Active Types ( with two, sometimes three, more reserved for special occasions ). A common example of a biological multi-strand protein grouping is: 4 strands will combine thusly - 2 strands of one type and 2 strands of another type.
