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 phosphotyrosine is shown below:

Step-by-step solution

What is hormone-signaling pathways?

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

What is phosphorylation?

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

Chemical structure of the Phosphotyrosine side chain:

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