What is the difference between essential amino acids and non-essential amino acids?
essential amino acid: ‘An essential amino acid or indispensable amino acid is an amino acid that cannot be synthesized de novo by the organism (usually referring to humans), and therefore must be supplied in the diet.’ http://en.wikipedia.org/wiki/Essential_a… ‘De novo is a Latin phrase, meaning “from the new,” anew, from scratch, or from the beginning. De novo synthesis refers to the synthesis of complex molecules from simple molecules such as sugars or amino acids, as opposed to their being recycled after partial degradation. For example, nucleotides are not needed in the diet as they can be constructed from small precursor molecules such as formate and aspartate. De novo synthesis also refers to DNA replication. Primase is an RNA Polymerase, and it can add a primer to an existing strand awaiting replication.
