The #1 Amino Acid In The World

What are Amino Acids?

Amino Acids are organic molecules that form the basic constituents of protein. Proteins are simply collections of large particles of accumulated links of peptides (or poly-peptides). In the digestion process proteins are broken down, a process called hydrolyzation, from poly-peptides to smaller oligo-peptides, then to di-peptides or tri-peptides, which are made up of two or three links of specific amino acids, called free-form amino acids, that are finally absorbed into the bloodstream. Therefore, we can see that amino acids are, quite simply, the most basic building blocks of proteins.
