Phytonadione
General Information
Phytonadione, also known as vitamin K1, is a fat-soluble micronutrient essential for plant growth and health. Its chemical name is 2-methyl-3-phytyl-1,4-naphthoquinone, denoting a multi-ring aromatic ketone structure. Phytonadione exhibits high stability against air and moisture but degrades under sunlight. It occurs naturally in green vegetation and plays a vital antioxidant role.
As an electron transporter, phytonadione facilitates photosynthetic electron flow to drive energy production. It also regulates protein function by activating certain enzymes involved in photosynthesis. Phytonadione mitigates oxidative damage from reactive oxygen species that are formed as byproducts of normal plant metabolism. Its antioxidant properties enhance drought tolerance in plants by preventing biomolecule destruction and membrane lipid peroxidation.
Phytonadione further enables plants to deal with environmental shocks like extreme temperatures, salinity and heavy metals. Its diverse bioactivities make phytonadione essential for maintaining the structural and functional integrity of plants under optimal and stressful conditions alike.
Adequate phytonadione nutrition promotes growth, boosts crop yield and improves post-harvest shelf life.
