Physiology & Medicine / Re: Why Do Insect Bites Itch?

Itching after an insect bite can be quite bothersome, but it actually serves a purpose. When a mosquito or other insect bites you, it injects saliva into your skin to prevent your blood from clotting. This saliva contains proteins that your immune system reacts to, causing an inflammatory response. The itching sensation is a result of this immune response. However, scratching too much can actually make the itching worse and may even break the skin.

It's true that silicon and carbon are close on the periodic table and both have similar properties, but carbon has a unique ability to form a large variety of molecules, including the complex molecules needed for life as we know it.
