Tryptophan (symbol Trp or W) is an α-amino acid that is used in the biosynthesis of proteins. Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a non-polar aromatic amino acid. It is essential in humans, meaning that the body cannot synthesize it and it must be obtained from the diet. Tryptophan is also a precursor to the neurotransmitter serotonin, the hormone melatonin, and vitamin B3. It is encoded by the codon UGG.
Like other amino acids, tryptophan is a zwitterion at physiological pH where the amino group is protonated (–NH3; pKa= 9.39) and the carboxylic acid is deprotonated ( –COO; pKa= 2.38).
Tryptophan food source, egg white (10mg/g), spirulina (9.3mg/g), sesame seed (3.7mg/g), cheese (3.2mg/g), sunflower seeds (3.0mg/g), turkey (2.4mg/g), chicken (2.4mg/g), oats (2.3mg/g), beef (2.3mg/g), salmon (2.2mg/g), egg (1.7mg/g), poultry, chickpeas (1.9mg/g), milk (0.8mg/g), bananas (0.1mg/g), chocolate (13.3ug/g), peanuts, almond, rice, quinoa, potatoes, dried dates, yogurt etc Minimum daily intake for tryptophan is 4mg per kg (or 2.2lbs) body weight.
AZ Sportivo Performance and AZSP Healing are Researching human body as a science from head to toe. Any pains, soreness, discomfort have reasons, root causes, we will find out and solve them as possible we can. Our approach is more neuromuscular and anatomical body structure than only muscles, more science and engineering to human body.
