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
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
Isoenzymes Definition: Different forms of the same enzyme that catalyzes the same biochemical reactions are called isoenzymes or isozymes. All the isozymes of a given enzyme are coded by different … Read more
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
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’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
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
Definition of activation energy: Some amount of energy must be put into get the reaction initiated. This energy is required to activate the substances to react. Hence, this energy is … Read more
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
ATP Definition: ATP molecule (Adenosine triphosphate) is an energy stored organic complex that provides energy to countless intracellular biological reactions. In animals, the breakdown of consumed carbohydrate molecules generates some … Read more
