Biological Role An essential amino acid for humans, meaning it must be obtained from the diet. Plays a role in protein structure (e.g., forming hydrogen bonds via its hydroxyl group) and functions as a precursor for biosynthesis of glycine, serine, and other compounds. Stereochemistry Exists in four stereoisomers due to two chiral centers (at α-carbon and β-carbon), but only L-threonine is naturally occurring and biologically active. Stability Stable under normal storage conditions when kept dry and away from light. Can be degraded by heat, strong acids, or bases, especially during prolonged exposure. These properties make L-threonine critical for nutritional supplements, food fortification, and pharmaceutical applications, while its chemical reactivity enables its use in peptide synthesis and biochemical research.
