kynurenine has been researched along with Menopause in 8 studies
Kynurenine: A metabolite of the essential amino acid tryptophan metabolized via the tryptophan-kynurenine pathway.
kynurenine : A ketone that is alanine in which one of the methyl hydrogens is substituted by a 2-aminobenzoyl group.
Menopause: The last menstrual period. Permanent cessation of menses (MENSTRUATION) is usually defined after 6 to 12 months of AMENORRHEA in a woman over 45 years of age. In the United States, menopause generally occurs in women between 48 and 55 years of age.
