Vitamin K3, molecular model
Vitamin K3, molecular model. The chemical formula for vitamin K3, now called menadione, is C11.H8.O2. Atoms are represented as spheres and are colour-coded: carbon (blue), hydrogen (gold) and oxygen (red). Menadione is a provitamin, a precursor to vitamin K2. Due to its high toxicity, its use as a nutritional supplement for vitamin K has been banned in most countries. Large doses can cause haemolytic anaemia (the destruction of red blood cells) in adults and brain damage, liver damage and even death in neonatal babies. However, low doses of menadione are still used in many countries as an inexpensive micronutrient supplement for livestock

EDITORS COMMENTS
This print showcases the intricate molecular model of Vitamin K3, also known as menadione. The chemical formula C11. H8. O2 represents this compound, with each atom represented by color-coded spheres: carbon in blue, hydrogen in gold, and oxygen in red. Menadione serves as a provitamin or precursor to Vitamin K2. However, despite its potential benefits, the use of menadione as a nutritional supplement for Vitamin K has been banned in most countries due to its high toxicity. In adults, large doses can lead to haemolytic anaemia - the destruction of red blood cells. Neonatal babies face even more severe consequences such as brain damage, liver damage, and sadly even death. Nevertheless, low doses of menadione are still utilized in many countries as an affordable micronutrient supplement for livestock. This highlights its significance within the agricultural industry. The striking visual representation of this molecule reminds us of the complex world of biochemistry and nutrition. It serves as a reminder that while certain compounds may hold promise for health benefits, their potential dangers must be carefully considered and regulated. This thought-provoking image from Science Photo Library offers a glimpse into the fascinating realm of molecular structures and their impact on our lives – both positive and potentially harmful.
