Question

Phytomenadione is
a. $\beta $- phylloquinone
b. $\alpha $- phylloquinone
c. ${K_1}$
d. Both B and C

Answer 1

Hint: Phytomenadione is a phytonadione that is used to treat vitamin K deficiency. It is used to treat some bleeding problems. It is also used to treat blood-clotting problems caused due to deficiency of Vitamin K. Vitamin K is, therefore, necessary for our body to conquer the blood clotting problems.

Complete answer:
- Phytomenadione, also known as vitamin ${K_1}$ or phylloquinone. It is a vitamin found in food and mainly other diet supplements that can be used to treat certain bleeding problems and clotting problems. The use of Phytomenadione is approved or advised by mouth or by use of injection. The injection is recommended. In the veins or muscles. They show effects within an hour. So, the correct option is D (both Band C)

- Phytomenadione is often also called as vitamin ${K_1}$ and phylloquinone. So, option C is incorrect.

The main source of Vitamin K is cabbage, green leafy vegetables like cauliflower, spinach, eggs, meat, milk. Phytonadione is considered as a synthetic form of vitamin K. It occurs naturally in the body or can be taken as a diet supplement in our food.

- $\beta $ - phylloquinone is used to treat vitamin deficiency, and to treat certain bleeding or blood-clotting problems which may occur in human beings. So option A is incorrect.

- $\alpha $ - phylloquinone is a precursor of vitamin – K. So, option B is incorrect.

Hence, the correct answer is option (D).

Note: vitamin ${K_1}$ (otherwise known as phylloquinone) occurs abundantly in green leaves as a quinone. Phylloquinone is best known for its electron transport role in photosystem I (in thylakoid membranes of chloroplasts). However, phylloquinone occurs at lower levels also in non-green tissues of plants, and increasing evidence indicates that it fulfills a general role in modulating the redox state needed for cell survival. A great deal remains to be discovered in plant biochemistry.
