What`s so great about Protein
... Proteins are compounds that are made by linking together amino acids into chains-like structures called peptides. One amino acid is joined to a second; a third is then added to the first two and so on. The bonds between amino acids are called peptide bonds. Peptides are then linked together into lon ...
