What determines the different shapes and functions of proteins?

Answer 1

A protein's structure is determined by:

- the amino acid sequences of its polypeptide chains;

- hydrogen bonds between amino acids in polypeptides;

- other bonds (e.g. hydrophobic interactions, disulphide bridges) between side chains in the polypeptides; and

- the arrangement of polypeptides (in a protein that contains more than one polypeptide)

Scientists have mapped the structures of several proteins; however, scientists are still unsure as to how proteins actually form their final structures.

The function of a protein is directly related to its structure. For example, a protein that fights a certain bacteria might have a shape that allows it to bind to the bacteria and then destroy it.

Answer 2

every protein is made up of a sequence of amino acids, these chains amino acids form protein, depending on the sequencing of the amino acids it makes a specific protein, like the protein keratin is found in hair, because this protein forms hair

Answer 3

The shape of a protein determines its function, and temperature and pH can affect the shape of a protein. The shape of a protein is determined by its amino acid sequence.

Answer 4

The R groups of amino acids that they contain

Answer 5

It determines what substrates it can interact with; the substrate has to be the same shape as to fit within the Enzyme's Active Site.

Answer 6

The amino acid sequence determines a protein's structure and function.

Answer 7

Its composition and shape.
