Protein Structure - Biology EncyclopediaProtein Structure Photo by: rob3000Proteins are chains of amino acids that fold into a three-dimensional shape. Proteins come in a wide variety of amino acid sequences, sizes, and three-dimensional structures, which reflect their diverse roles in nearly all ...
Novel mechanisms in cell biology have been uncovered through disease-orientated research; for example, the discovery of presenilin as an intramembrane aspartyl protease that processes many diverse proteins within the lipid bilayer. A common theme has arisen in this field: normally-soluble proteins ...
But when it’s time to make proteins, especially those that are for transport outside the cell or for use by the cell membrane, they will assemble on the surface of the rough endoplasmic reticulum.» Rough ER is primarily involved in protein synthesis. Together with the ribosomes, the ...
In cell-mediated immunity, stimulated T H cells activate T C cells. All cells of the body produce surface proteins called class I MHC proteins. If the cell is abnormal (cancerous or infected with a virus), the abnormal antigen is displayed with the class I MHC protein. A T C cell with...
Proteins surrounded by more than one subunit have a quaternary structure. What is the function of quaternary structure of proteins? The quaternary structure of a protein allows it to fulfill many different functions. Proteins with the structural organization are involved in gene expression, ...

Describe four major functions of proteins in the human body with one example for each. How do enzymes initiate chemical reactions? What is the common catabolic pathway? What is a stimulus response in biology? How is food rearranged through chemical reactions? What is chemical work in biolo...
Biology is a wide-ranging field. It encompasses various fields in science, such as chemistry, physics, mathematics, and medicine. Biochemistry, for instance, is biology and chemistry combined. It deals primarily with the diverse biomolecules (e.g. nucleic acids, proteins, carbohydrates, and lipids...
