phylloquinone การใช้

• Vitamin K1 is called phylloquinone and comes from our diet.
• Phylloquinone's tight binding to thylakoid membranes in chloroplasts makes it less bioavailable.
• The reason is that phylloquinone, the most common form of the vitamin, is directly involved in photosynthesis.
• Phylloquinone A 1 is the next early electron acceptor in PS I . Phylloquinone is also sometimes called vitamin K 1.
• Phylloquinone A 1 is the next early electron acceptor in PS I . Phylloquinone is also sometimes called vitamin K 1.
• The vitamin K content of leaf vegetables is particularly high, since these are photosynthetic tissues and phylloquinone is involved in photosynthesis.
• MK-7 may be converted from phylloquinone ( K 1 ) in the colon by " E . coli " bacteria.
• :peptidyl-4-carboxyglutamate + 2, 3-epoxyphylloquinone + H 2 O \ rightleftharpoons peptidyl-glutamate + CO 2 + O 2 + phylloquinone
• Phylloquinone A 1 oxidizes A 0 in order to receive the electron and in turn reduces F x in order to pass the electron to F b and F a.
• Vitamin K 1, also known as phylloquinone, is made by plants, and is found in highest amounts in green leafy vegetables because it is directly involved in photosynthesis.
• The two important forms are Vitamin K ( phylloquinones ) which occurs naturally in green plants, and Vitamin K2 ( menaquinone ) which is a product of bacterial synthesis in the intestines.
• For example, cooked spinach has a 5 % bioavailability of phylloquinone, however, fat added to it increases bioavailability to 13 % due to the increased solubility of vitamin K in fat.
