详细说明

DrugBank - DB00156

• Drug Groups: approved; nutraceutical
• Description: An essential amino acid occurring naturally in the L-form, which is the active form. It is found in eggs, milk, gelatin, and other proteins. [PubChem]
• Indication: L-Threonine makes up collagen, elastin, and enamel protein. It aids proper fat metabolism in the liver, helps the digestive and intestinal tracts function more smoothly, and assists in metabolism and assimilation.
• Pharmacology: L-Threonine is an essential amino acid that helps to maintain the proper protein balance in the body. It is important for the formation of collagen, elastin, and tooth enamel, and aids liver and lipotropic function when combined with aspartic acid and methionine.
• Affected Organisms: Humans and other mammals
• Biotransformation: Hepatic
