primary Protein Structure & Function

Question 1

There are four levels of structure in proteins, three are related to a single polypeptide chain and the fourth level relates to a protein that has two or more polypeptide chains

Polypeptide or protein molecules can have anywhere from 3 amino acids (Glutathione) to more than 34,000 amino acids (Titan) bonded together in chains

Question 2

What is the primary structure of a protein

Answer 2

The sequence of amino acids bonded by covalent peptide bonds is the primary structure of a protein

Question 3

What determines the primary structure of a protein

and how does differed the proteins primary structure this affect

Answer 3

DNA of a cell determines the primary structure of a protein by instructing the cell to add certain amino acids in specific quantities in a certain sequence.

This affects the shape and therefore the function of the protein

Question 4

How many amino acids in living organisms

Answer 4

How many amino acids in living organisms

Question 5

What is a protein

Answer 5

Proteins are made up of repeated units of amino acids which link with each other via peptide bonds
