Albumin is a protein that is found in eggs.
Which of the following describes the structure of albumin?
Choose 1 answer:
A molecule containing carbon, hydrogen, and oxygen in a 1:2:1 ratio
B
A chain of amino acids folded and twisted into a molecule
Three fatty acids attached to one glycerol molecule
D
A series of nitrogenous bases attached to a sugar-phosphate backbone

Proteins are organic compounds containing carbon, hydrogen, oxygen, and nitrogen. Amino acids are compounds that consist of an R group, carboxylic acid end, and amino end. A chain of amino acids is referred to as a protein.

The statement 'a chain of amino acids folded and twisted into a molecule' describes the structure of albumin (Option B).

Proteins are macromolecules composed of a long sequential chain of amino acids linked together by peptide bonds.

All proteins must be twisted and folded by a cellular mechanism called protein folding, which becomes an inactive polypeptide chain into a functionally active protein.

Protein folding modifies the tridimensional (3D) conformation of a protein in order to become it into a biologically active molecule that performs specific functions (e.g., an enzyme with catalytic functions).

In conclusion, the statement 'a chain of amino acids folded and twisted into a molecule' describes the structure of albumin (Option B).
