Definition of threonine in English:

threonine

noun ˈθriːəniːnˈTHrēəˌnēn

mass nounBiochemistry

A hydrophilic amino acid which is a constituent of most proteins. It is an essential nutrient in the diet of vertebrates.
Chemical formula: CH₃CH(OH)CH(NH₂)COOH
Example sentencesExamples
- In animal cells serine, threonine and tyrosine are the amino acids subject to phosphorylation.
- The essential amino acids are histidine, tryptophan, threonine, valine, phenylalanine, leucine, methionine, lysine, and isoleusine.
- The aspartate can be used as a precursor for the synthesis of other amino acids such as asparagine, threonine, isoleucine, leucine, valine, lysine, and methionine.
- Nitrogen limitation in plants could explain the use of the polar amino acids serine and threonine instead of nitrogen-containing asparagine as in P. falciparum.
- The amount of the amino acids threonine, proline and histidine were also increased in roots of slag-cultivated maize plants.

Origin

1930s: from threose (the name of a tetrose sugar) + -ine⁴.
