Vitamin K - 새창 A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (VITAMIN K 1) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.
Synonyms :
Vitamin K 1 - 새창 A family of phylloquinones that contains a ring of 2-methyl-1,4-naphthoquinone and an isoprenoid side chain. Members of this group of vitamin K 1 have only one double bond on the proximal isoprene unit. Rich sources of vitamin K 1 include green plants, algae, and photosynthetic bacteria. Vitamin K1 has antihemorrhagic and prothrombogenic activity.
Synonyms : Aquamephyton, Konakion, Phyllohydroquinone, Vitamin K1
Vitamin K 2 - 새창 A group of substances similar to VITAMIN K 1 which contains a ring of 2-methyl-1,4-naphthoquinione and an isoprenoid side chain of varying number of isoprene units. In vitamin K 2, each isoprene unit contains a double bond. They are produced by bacteria including the normal intestinal flora.
Synonyms : Menaquinones, Vitamin K Quinone, Vitamin K2
Vitamin K 3 - 새창 A synthetic naphthoquinone without the isoprenoid side chain and biological activity, but can be converted to active vitamin K2, menaquinone, after alkylation in vivo.
Synonyms : 2-Methyl-1, 4-naphthalenedione, 2-Methyl-1, 4-naphthoquinone, 2-Methylnaphthoquinone, Menadione bisulfite, Menadione sodium bisulfite, Menadione sodium bisulfite, trihydrate, Vicasol, Vikasol, Vitamin K3, Vitamin K3 sodium bisulfite
Vitamin K Deficiency - 새창 A nutritional condition produced by a deficiency of VITAMIN K in the diet, characterized by an increased tendency to hemorrhage (HEMORRHAGIC DISORDERS). Such bleeding episodes may be particularly severe in newborn infants. (From Cecil Textbook of Medicine, 19th ed, p1182)
