Where do proteins come from?

I’m working out. I need to eat proteins. So I eat things like meat and beans. But who makes the proteins first and how? Why can’t I make them myself?

There are many thousands different protiens in your body. .

Your body builds the protiens it needs. The building blocks, the amino acids are what are actually needed. Your body break down the protiens you eat into the building blocks and builds the protiens it needs from those pieces.

There are 20 different ammino acids that we build our protiens from and your body can only make 11 of these. You must consume amino acids or protiens that break down into amino acids to get the rest.

Other orginisms are able to build different amino acids, which we then eat to get those ones we need but can’t build ourselves.
