Learn about polypeptides. Understand what a polypeptide is, the formation of the polypeptide from peptides, the polypeptide structure, and examples...

What is a polypeptide chain? The definition of a polypeptide chain is a string of amino acids connected together by peptide bonds. The word poly means many, and the word peptide refers to proteins.

Explore the structure of polypeptides in just 5 minutes! Discover its formation and see real-life examples, followed by an optional quiz for practice.

Uncover the definition and structure of a polypeptide chain in just 5 minutes! Learn about its composition and function, then test your knowledge with a quiz.

The primary sequence of a protein is the order of the amino acids in the polypeptide chain. The primary structure is coded for in the DNA of organisms and can be read through protein synthesis.

Ribosomes live on the endoplasmic reticulum surrounding the nucleus and are key in the process of polypeptide assembly. This is essential for genetic translation because amino acid chains are ...

How do amino acids make proteins? Amino acids join together in a sequential order to form a polypeptide chain. One or more polypeptides form a protein. How do amino acids join together?

Learn what protein synthesis is, the process proteins are created by, the purpose of protein synthesis, and some functions of proteins, such as muscle contraction.

The way the polypeptide chain forms hydrogen bonds determines the secondary structure. There are two main types of secondary structures in proteins, alpha helices and beta pleated sheets.

The secondary level of protein structure is when certain regions of the polypeptide form specific, well-characterized shapes. In particular, certain subsets of amino acids can become either an α ...
