O-Phosphothreonine

(2S,3R)-2-Amino-3-hydroxybutanoic acid 3-phosphoric acid

C4H10NO6P (199.024573)


Phosphothreonine is a phosphoamino acid. It is the phosphorylated ester of threonine. There are three amino acids that are typically phosphorylated in eukaryotes: serine, threonine, and tyrosine. Threonine residues in endogenous proteins undergo phosphorylation through the action of a threonine kinase. Small amounts of free phosphothreonine can be detected in urine [PMID: 7693088].

O-Phosphohomoserine

L-2-amino-4-Hydroxy-butyric acid dihydrogen phosphate (ester)

C4H10NO6P (199.024573)


O-phosphohomoserine is a naturally occurring analogue of phosphonate amino acids. O-phosphohomoserine has been found in trace amounts in shotgun-metabolomics analysis in mouse tissue extracts, and is the substrate of a threonine analog enzyme in murine species. O-phosphohomoserine, an analogue of the excitatory amino acid antagonist 2-amino-phosphonovalerate is an N-methyl-D-aspartate (NMDA) antagonist.

C6H8NaO6 (199.0218568)


Antioxidant, antimicrobial agent, appearance control agent, curing accelerator for baked goods, meat and cured meat products. Restricted use in Japan. Sodium erythorbate (C6H7NaO6) is a food additive used predominantly in meats, poultry, and soft drinks. Chemically, it is the sodium salt of erythorbic acid. When used in processed meat such as hot dogs and beef sticks, it reduces the rate at which nitrate reduces to nitric oxide, thus retaining the pink coloring. As an antioxidant structurally related to vitamin C, it helps improve flavor stability and prevents the formation of carcinogenic nitrosamines. When used as a food additive, its E number is E316.

Antioxidant, antimicrobial agent, appearance control agent, curing accelerator for baked goods, meat and cured meat products. Restricted use in Japan. Sodium erythorbate (C6H7NaO6) is a food additive used predominantly in meats, poultry, and soft drinks. Chemically, it is the sodium salt of erythorbic acid. When used in processed meat such as hot dogs and beef sticks, it reduces the rate at which nitrate reduces to nitric oxide, thus retaining the pink coloring. As an antioxidant structurally related to vitamin C, it helps improve flavor stability and prevents the formation of carcinogenic nitrosamines. When used as a food additive, its E number is E316. Antioxidant, antimicrobial agent, appearance control agent, curing accelerator for baked goods, meat and cured meat products. Restricted use in Japan
