Question

Do proteins have specific shapes?

Answer 1

Proteins:

1. One or more extended chains of amino acid residues make up the large biomolecules and macromolecules known as proteins.
2. The chemical "building blocks" that makeup proteins are known as amino acids.
3. Our body uses amino acids to make enzymes, hormones, and to build and repair muscles and bones.
4. They can also be used as a source of power.
5. Each amino acid in a protein molecule is connected to its neighbour through a covalent peptide bond.
6. Polypeptides are another name for proteins.
7. Proteins take on specific forms.
8. These are created as a result of the particular interactions and sequence of amino acids.

Shapes of proteins:

1. A protein chain does not exist everywhere as an extended thread.
2. It is folded into secondary and tertiary structures and different subunits.
3. These assemble together to form a quaternary structure, which gives it the specific shape.

So, yes, protein do have a particular form.
