1. Amino acids are often broken down into two groups, essential and nonessential. Essential amino acids must be eaten in order to survive as we don’t make them. This is why intaking a certain amount of protein is so important to the body. In one of the greatest scientific finds of the 21st century, amino acids were discovered inside meteorites that had impacted the earth. Interestly, the amino acids contained different side chains and configurations than those found on earth....
