Amino Acids Part IV

Venn Diagram of Amino Acids.Image via Wikipedia
As we learned before, in humans dietary proteins are broken down by digestion into amino acids, which serves as metabolic fuel for other functional roles in the body. The non essential amino acids are those who are made by our body.
But as most are made from essential amino acids, by lack thereoff, we also can sometimes have a lack of non essential amino acids. 
Non essential amino acids are:
*glycine which feed brain, anterior pituritary, gallbladder, muscles, stomach
*aline feeds the liver,
*cysteine nourishes blood, pancreas, lungs
*proline for a healthy skin
*glutamine for the gastrointestinal tract, stomach, brain
*tyrosine for the  thyroid
*tyrosine feeds the brain
*asparagine for the nervous system  It also plays an important role in the synthesis of ammonia. Asparagus is a main source.
*aspartic acid serves as an excitatory neurotransmitter in the brain and is an excitotoxin.
*glutamic acid  is involved in cognitive functions like learning and memory in the brain . Kombu is an  excellent source. 
*Serine is important in metabolism as it participates in the biosynthesis of purines and pyrimidines. It is also the precursor to several amino acids, including glycine, cysteine, and, in bacteria, tryptophan.
