Threoninecontaining
Threoninecontaining is an adjective used in biochemistry and molecular biology to describe molecules that include the amino acid threonine in their composition. The term is most commonly encountered in reference to proteins and peptides, but can also apply to small molecules in which threonine is part of the structure. Threonine is one of the 20 standard amino acids and is essential in humans, meaning it must be obtained from the diet. In proteins, threonine residues may contribute to structural stability and function. The side chain’s hydroxyl group permits phosphorylation and glycosylation, processes central to signaling and regulation. In peptides, threonine-containing sequences or dipeptides denote peptides that include at least one threonine residue. In nutritional and industrial contexts, threonine-containing formulations may be used to supplement essential amino acids in feeds or to design peptide-based therapeutics. In analytical work, identifying threonine-containing components involves amino acid analysis, sequencing, or mass spectrometry to confirm the presence and position of threonine.
The hyphenated form threonine-containing is more common in literature; "threoninecontaining" without a hyphen is less standard
