There are many types of amino acids in various combinations to make hundreds of thousands of different proteins even the poison of a snake or mushroom consists of proteins, but also a piece of meat or a head of lettuce ....... so although protein are essential for our body, it is therefore important that we are the 'good' one  and not the bad.
