why are there enorormous numbers of different kinds of proteins?

Answer 1

There are more than 10 types of amino acids and each protein molecule is made up of 1000s of amino acids. This is one reason that constitute the large variety of proteins.
Another reason is the protein folding. Each amino acid has different bonding ability which determines the protein bonding which then determines the shape of the each protein.

Answer 2

Proteins are made up of a sequence of amino acids, of which there are 20 different types (at least in humans). Some of the smallest proteins are about 50 amino acids long but the majority are hundreds and even thousands of amino acids in length. Consider one position for an amino acid in a protein, that one position can have 20 different combinations. Consider two positions for an amino acid in a protein, the possible combinations using the 20 different amino acid for those 2 positions is 20^2 which is 400. So if all proteins where made up of 2 amino acids, there would be 400 different types. Now consider the fact that most proteins are hundreds and even thousands of amino acids in length, and you have such great amounts of combinations that there is practically endless amounts of proteins that can be made. And even then, this is only the primary structure of a proteins. Proteins have a secondary, tertiary and quaternary structure that will lead to even more possible proteins. In reality, the possibilities are so great that we can assume that there are endless amounts of proteins which can be synthesized.

Answer 3

Theoretically there are an infinite number of proteins. Proteins are made from chains of amino acids. You can take an existing protein and add another amino acid to it, now you have a new protein. Now add another amino acid to this protein, and you have second new protein. Now add another amino acid to the second new protein... and on and on and on. The possibilities are endless.
A protein can be made of three amino acids, or four amino acids, or five,or a thousand or ten thousand... keep adding amino acids, keep getting different proteins.
All of the proteins in living things are made from only 20 biologically important amino acids.

Answer 4

properly, maximum proteins are tens of hundreds of Amino Acids in length. those 20 all have diverse chemical residences that lead them to pull the strand of amino acids in diverse guidelines, some faraway from water, some in direction of water, others in, out, and around, nevertheless others respond to pH. it particularly is the perfect conformation of the protein, purely as lots with the aid of fact the amino acids it particularly is created from, that be sure a protein's function. The cellular is stated via regulatory molecules around its DNA to offer proteins. permit's say that a cellular produces compound A. each and every time there is alot of compound A, a number of it gets returned into the nucleus and binds with a regulatory "provide up" molecule, receptor A. Then the cellular will provide up making greater compound A with the aid of fact it is familiar with that it has adequate. each and every time there is far less compound A, there should not be any sure to receptor A, and it will proceed to offer compound A till a number of it returned binds with the provide up molecule. different cases, a gene could properly be activated if there is too lots of something. to illustrate, permit's say a cellular absorbs alot of compound B. a number of it particularly is going to bind with a "start up" molecule, receptor B. In reaction, the cellular will then produce alot of enzyme C to break down compound B. at last, there will be so little compound B that it particularly is no longer sure to receptor B, and so the cellular will provide up making enzyme C. and that's how a cellular "is familiar with" what proteins to make. usually, the easily pathways are lots greater complicated, yet those examples exhibit the needed areas of the approach.

Answer 5

There are proteins that are enzymes (catalysts), enzymes that provide structure for the cell, and other functional enzymes (such as ion pumps and other cell surface channels). Cells are complex, and lots of controlled chemical reactions take place within them. Each of those controlled chemical reactions is controlled by a different enzyme.
