Protein

Proteins are long-chain molecules built from small units known as amino acids. They are joined with peptide bonds. They are biochemical compounds.They...

Protein biosynthesis (synthesis) is when cells build proteins. The term is sometimes used to refer only to protein translation but more often it refers...

A globular protein is one of a common type of protein. They are one of three types of protein. The others are fibrous and membrane proteins. Their structure...

A molecular chaperone is a protein which does things to other proteins. They are mostly concerned with protein folding. Some help assemble or take apart...

Protein structure describes how protein molecules are organised. This structure is what makes proteins work. Proteins are important biological macromolecules...

Protein folding is how a protein gets its functional shape or 'conformation'. It is mainly a self-organising process. Starting from a random coil, polypeptides...

The Protein Data Bank (PDB) is a collection of information about the three dimensional (3-D) structure of large biological molecules, such as proteins and...

A fibrous protein or scleroprotein is one of the three main types of proteins. The others are globular and membrane proteins). There are many types of...

A membrane protein is a protein molecule that is attached to, or associated with the membrane of a cell or an organelle. 20–30% of all genes in genomes...

Green florescent protein (GFP) is a protein that is found in moon jellyfish. It helps scientists look at cell molecules. There is another substance the...

An ion channel is a pore-forming protein that helps to establish and control the small voltage gradient across the plasma membrane of all living cells...

of biochemistry involves enzymes, nucleic acids, carbohydrates, sugars, proteins, and lipids. In the body, most of the molecules are polymers built of long...

A Spike protein or peplomer is a glycoprotein spike on the outside layer (or capsid) of a virus. When a virus attaches to a cell, these peplomers can...

5' AMP-activated protein kinase (AMPK) is an enzyme (EC 2.7.11.31) that helps keep the body's energy balanced. It is found in many parts of the body,...

non-protein hormones, waste, lipids, and proteins. These proteins are albumin, antibodies (also called immunoglobulins), clotting factors, and protein hormones...

many people because it has protein. Protein helps the growth and healing of a body and gives energy. Meat is a "high-protein" food, but costs more than...

In biology, a filament is a long chain of proteins, such as those found in hair, muscle, or in flagella. http://www.ucmp.berkeley.edu/glossary/gloss4cell...

which is not a protein, but is attached to a protein. The compound is needed for the protein's biological activity. In most cases, the protein will be an...

Other proteins and lipids can be added to the cell membrane. By these changes, the cell can adjust what it brings in or puts out. Some proteins are always...

1950s Crick helped sort out the way proteins are synthesized. In 1958, Crick's listed all the key features of the protein synthesis process: genetic information...
