To understand how a protein gets its final shape or conformation, we need to understand the four levels of protein structure: primary, secondary, tertiary, and quaternary.

Each protein in your cells consists of one or more polypeptide chains. Each of these polypeptide chains is made up of amino acids, linked together in a specific order.

Now, any protein that's made up of a single polypeptide is only going to have primary structure, secondary structure and tertiary structure, but if we're dealing with something like hemoglobin, that's …

The four levels of protein structure are primary, secondary, tertiary, and quaternary. It is helpful to understand the nature and function of each level of protein structure in order to fully understand how …

Learn about the structure of proteins and the diverse roles these molecules play in the cell.

This article goes over the forces driving protein folding and the forces that stabilize protein structure, as well as causes of protein denaturation.

Amino acids are the essential building blocks of proteins, which carry out almost every function in our bodies. Each protein’s unique composition of amino acids determines its specific structure and …

Proteins, large biomolecules or macromolecules, play a vital role in almost every biological process. They are made up of chains of amino acids, which are their building blocks. These chains, known as …

Albumin is a protein that is found in eggs. Which of the following describes the structure of albumin?

A new drug is developed which selectively cleaves covalent bonds between two sulfur atoms of non-adjacent amino acids in a polypeptide chain. Which level of protein structure in affected molecules …
