Vitamin B12 and coenzyme molecule
Vitamin B12 and coenzyme. Molecular model of vitamin B12 in its cofactor (active) form. Cofactors are compounds that are bound to a coenzyme. An enzyme is a protein that catalyses metabolic reactions. Coenzymes need specific molecules to bind to them in order to function. Atoms are represented as spheres and are colour- coded: carbon (blue), hydrogen (gold), cobalt (dark red, centre), nitrogen (dark blue), oxygen (red) and phosphorus (purple). Vitamin B12 is an essential nutrient that humans are unable to produce and so need to obtain from their diet. It is found in meat, fish poultry and dairy products. It is needed for producing red blood cells and for a healthy nervous system. Deficiency can lead to pernicious anaemia, with symptoms including tiredness, dizziness and a reduced sense of taste

EDITORS COMMENTS
This print showcases the intricate molecular structure of Vitamin B12 and its coenzyme in their active form. The image beautifully illustrates the vital role that this compound plays in our bodies. Vitamin B12, an essential nutrient for humans, cannot be produced internally and must be obtained through our diet. It is commonly found in meat, fish, poultry, and dairy products. This molecule is crucial for the production of red blood cells and maintaining a healthy nervous system. The photograph highlights how coenzymes are compounds bound to specific molecules required for their proper functioning within our biochemistry. Enzymes, represented as proteins catalyzing metabolic reactions, rely on these coenzymes to carry out their tasks effectively. The color-coded spheres representing different atoms provide a visually appealing representation of the molecular composition: carbon (blue), hydrogen (gold), cobalt (dark red at the center), nitrogen (dark blue), oxygen (red), and phosphorus (purple). Understanding this complex biochemical process is key to comprehending how deficiencies in Vitamin B12 can lead to pernicious anemia with symptoms such as fatigue, dizziness, and reduced taste sensation. Overall, this thought-provoking image offers a glimpse into the fascinating world of biochemistry while emphasizing the importance of incorporating Vitamin B12 into our dietary routines for optimal health.
