Four levels of protein structure and examples

Primary Protein structure of protein

Protein structure basically depends on the arrangement of different amino acid residues in a three-dimensional way. In general, proteins are macromolecules and have four different levels of structure. Four levels … Read more

Four Levels of protein structure

The term structure when used in the relation to proteins, takes on a much more complex meaning than it does for small molecules. Proteins are macromolecules and have four different … Read more

Role of Metal Ions in Biological Systems

Metal ions are important factors in cellular metabolism, as they function as enzyme cofactors and thus modulate the activity of enzymes and enzymatic reactions. Although several enzymes have been reported … Read more

Types of Enzyme Inhibition

Enzyme Inhibition Definition: The decline in the velocity of an enzymatic reaction is called enzyme inhibition. In other words, enzyme inhibition refers to a reduction in enzyme-related processes, enzyme activity, … Read more

Anfinsen experiment components and conclusion

Anfinsen’s experiments indicated that the formation of higher-order structure mainly depends on the nature and type of amino acids present in the primary structure. Anfinsen experiment in protein folding used … Read more

Examples of Cofactors and Coenzymes

Examples of Cofactors and Coenzymes

Complex enzymes are made up of protein and nonprotein components. The protein part of the enzyme is called Apoenzymes or Apozyme. While the non-protein part of the enzyme is called Cofactor. … Read more

DNA as Genetic Material – Evidence

DNA as Genetic Material Griffith Transformation Experiments

DNA is a chemical substance that makes genes of all organisms ranging from prokaryotes (bacteria) to higher organisms (humans). Interestingly, the non-living organism such as virus also contains DNA as … Read more
