Question

Some hormone-signaling pathways result in the phosphorylation of tyrosine resides in proteins. Draw the structure of a phosphotyrosine side chain.

Short answer

The Chemical structure of the phosphotyrosine is as follows:

Step-by-step solution

Hormone-signaling pathways

The signaling pathways which are induced by the hormones to regulate the cell function are hormone-signaling pathways.

Phosphorylation

Phosphorylation is the chemical addition of the phosphate groups to organic molecules.Phosphorylation is the mechanism which regulates the process of cell signaling mechanism. It plays a critical role in the regulation of various cell cycle processes like cell cycle, cellular growth, apoptosis etc.

Importance of tyrosine phorphorylation

Tyrosine phosphorylation is required for posttranslational modification. It initiates a series of signaling pathways that regulate proliferation, adhesion and migration of cells.

Chemical structure of the Phosphotyrosine side chain:

Hence, the mechanism of phosphorylation and the chemical structure of the Phosphotyrosine was understood.
