The regulation of the activation of these catalyzing enzymes is needed in order to regulate the whole reaction speed, so that it is possible to obtain the amount of product required at any time, that makes regulatory enzymes have a biological importance. Therefore, regulatory enzymes, by its controlled activation and are of two types ...
The main function of hormone-sensitive lipase is to mobilize stored fats. [13] HSL functions to hydrolyze either a fatty acid from a triacylglycerol molecule, freeing a fatty acid and diglyceride, or a fatty acid from a diacylglycerol molecule, freeing a fatty acid and monoglyceride. This process allows energy metabolism in mammals. [12]
Protein metabolism denotes the various biochemical processes responsible for the synthesis of proteins and amino acids (anabolism), and the breakdown of proteins by catabolism. The steps of protein synthesis include transcription, translation, and post translational modifications.

It raises the concentration of glucose and fatty acids in the bloodstream and is considered to be the main catabolic hormone of the body. It is also used as a medication ...
The precise regulation of PFK1 prevents glycolysis and gluconeogenesis from occurring simultaneously. However, there is substrate cycling between F6P and F-1,6-BP. Fructose-1,6-bisphosphatase (FBPase) catalyzes the hydrolysis of F-1,6-BP back to F6P, the reverse reaction catalyzed by PFK1. There is a small amount of FBPase activity during ...
Binding of insulin to the α-subunit results in a conformational change of the protein, which activates tyrosine kinase domains on each β-subunit. The tyrosine kinase activity causes an autophosphorylation of several tyrosine residues in the β-subunit. The phosphorylation of 3 residues of tyrosine is necessary for the amplification of the ...
Glycogenolysis takes place in the cells of the muscle and liver tissues in response to hormonal and neural signals. In particular, glycogenolysis plays an important role in the fight-or-flight response and the regulation of glucose levels in the blood.
Glycogenesis responds to hormonal control. One of the main forms of control is the varied phosphorylation of glycogen synthase and glycogen phosphorylase. This is regulated by enzymes under the control of hormonal activity, which is in turn regulated by many factors.
