Protein structure and function

In 1960, the British biochemist John Kendrew used a method called ‘X-ray diffraction’ to photograph myoglobin at a 2 A resolution and became...

4 classes of protein structure • Primary • Secondary • Tertiary • QuaternaryKEY PROTEIN FUNCTIONS • Accelerate reactions • Provide structural support • Send communication signals • Aid in cellular movement • Provide immune defense • Storage of nutrients (nitrogen) "Structure determines function."CLASSES OF PROTEIN STRUCTURE 1. Primary protein structure • Together, peptide bonds and amino acids form a polypeptide chain (aka a protein). • The primary structure of a protein determines its…

What is the difference between Integral and Peripheral Proteins? Integral proteins are embedded in the whole bilayer while peripheral proteins are located..

DNA and RNA are nucleic acids that play essential roles in genetic coding but have different structures and functions. Learn their differences and roles here!

Proteins are the largest and most varied class of biological molecules, and they show the greatest variety of structures. Many have intricate three-dimensional folding patterns that result in a compact form, but others do not fold up at all ("natively unstructured proteins") and exist in random conformations. The function of proteins depends on their structure,

RIBONUCLEIC ACID STRUCTURE & FUNCTION: Ribonucleic acid (RNA) functions as genetic messengers and builders of the cellular world. Here are the basics on this important biomolecule.

A nucleotide is an organic molecule that is the building block of DNA and RNA. They also have functions related to cell signaling, metabolism, and enzyme reactions. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base.
