Coined/History 
Threonine was discovered in 1930 by American nutritionist William Cumming Rose (1887-1985) in Illinois University. Its name derived by the similarity with  monosacharite threose (C4H8O4) an isomer of D-erythrose.  Erythrose's name derived by erythrin-erythritol which isolated from red lichens.
 Definition
Threonine is an essential amino acid  that helps for protein balance in the body, gut integrity and immunity by aiding in production of antibodies. It is needed for gycine and serine formation which are required for collagen production. Threonine is mostly found in the central nervous system. It is found in foods such as  cottage cheese, poultry, lentils, fish, meat and sesame seeds.
