What are the chemical contents of beef stock? [closed]

I am familiar with the average beef stock recipe. After the liquid is strained, what are its chemical contents, exactly? Is it just water + denatured animal cell proteins? Does it contain collagen? What would I see if I looked at it under an electron microscope?

I'd say, take all this with a grain of salt (pun) and enjoy your cup of broth as is.
