Summary Introduction

Introduction:

The one or more amino acid chains present in the proteins are known as polypeptides. Proteins with two or more linked polypeptides form the quaternary structure. The distortion in the structure of protein leads to the destruction of its secondary and tertiary structure.

Students have asked these similar questions
Proteins are synthesized by a reaction called__________synthesis, which releases______________ . Subunits of proteins are called________ . The sequence of protein subunits is called the_________ structure of the protein. Two regular configurations of secondary protein structure are__________ and________ . When a protein’s secondary or higher-order structure is destroyed, the protein is said to be__________ .
In protein synthesis, adenine pairs with ________________________, and guanine pairs with ________________________.  Multiple Choice   uracil; cytosine   adenine; guanine   None of the answer choices are correct.   thymine; cytosine   thymine; uracil
At what level of protein structure (primary, secondary, tertiary, or quaternary) will protein structure be initially altered? Heating a protein (due to fever), causing hydrogen bonds to break. Drastic changes in pH (like the above patients), causing some polar amino acids to turn into non-polar amino acids
