Protein structure

By convention, a chain under amino acids is often identified as a peptide, rather than a protein. Orders of protein structure : primary, secondary, tertiary, and quaternary. Alpha helix and beta pleated sheet. May Amino acids, linked together by peptide bonds, form a polypeptide chain. Globular and fibrous proteins may exhibit one or more of four types of protein structure.

A single protein molecule may contain one or more of the protein structure types: primary, secondary, tertiary, and. Overview of the protein structure. Learn how their functions are based on their three-dimensional structures , which emerge from a complex folding process.
