Amino acids are organic molecules that will form the structural pillars to form proteins. These are going to be made up of a structure having in common all of them a carboxyl group, an amino group and a radical group that is in which they are going to differentiate to have their own property.
Animoacids not only have the structure to form proteins but can also be messengers for certain nervous reactions or also for the biosynthesis of porphyrins, purines, pyrimidines and urea.
Thanks to the R group and the difference of each amino acid in it, 20 types of amino acids are known.
Amino acids will also be involved in the regulation and maintenance of the body since they will also be part of enzymes or hormones.
