What is Threonine
Τhreonine is a major component of structural proteins such as collagen and elastin, which are important components of skin and connective tissue. It also plays a role in fat metabolism and immune function.
The human body does not have the ability to biosynthesize threonine, so it must receive it ready-made from food, i.e. it is an essential amino acid.
The chemical properties of threonine are largely determined by the presence of hydroxyl, which makes the side chain polar and at the same time allows post-translational modifications of the amino acid such as glycosylation and phosphorylation.
Threonine, like serine, is a hydrophilic amino acid and is found mainly in the periphery of water-soluble proteins.
