Where do proteins come from?

Question

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?

Answer 1

Living things make proteins, and are made in part of proteins. Eating more proteins than normal enables making more proteins than normal, which helps when building muscle. Specifically, the proteins you eat are broken down to their amino acid building blocks, and reassembled to new proteins as needed.
