Ineed asap what does the three-dimensional structure below most likely represent? a) the linear order of amino acids in a polypeptideb) the overall spatial arrangement of atoms of a polypeptidec) the three-dimensional structure that is created by folding a polypeptided) the arrangement of a number of polypeptides folded into a larger complex

D

Explanation:

There are four types of protein structures:

1. Primary Structure - linear order of amino acids in a polypeptide

2. Secondary Structure - folding of the amino acids into a repeated pattern due to hydrogen bonding of the polypeptide backbone

3. Tertiary Structure - the three dimensional structure created by a single polypeptide

4. Quaternary Structure - the arrangement of a number of polypeptide (two or more) folded into a larger complex.

The figure shows the Quaternary structure found in proteins, as is evident from the two different polypeptide chains (identified as light grey and a darker grey) that fold into a complex. This structure is often held together by van der waals forces, ionic bonds, hydrogen bonds, and in some cases, covalent bonds.

the answer to this question is 3.
