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?
In: Biology
You do make proteins. All of your enzymes and antibodies that you use to survive are examples of proteins. There are regions of your DNA known as exons which are read by specialized enzymes in your cells. These enzymes essentially copy a mirror image (known as mRNA) that gets sent to a large protein unit called a ribosome which translates that mRNA into an amino acid sequence called a peptide. Peptides join together to make a protein. Those single building blocks known as amino acids can’t always be made by us, so when you eat protein, you give your body a lot more access to a bunch of amino acids to use to make the proteins we need!
