Scientists discovered that certain bacterial proteins contain lids which open when vitamin B12 comes near, taking in its nourishment. Once in, B-12 is converted to its various forms; such as methylcobalamin, adenosylcobalamin and hydroxocobalamin.
Genetic mutations that disrupt intracellular vitamin B12 metabolism lead to defects in complementation groups cblA, cblC and mut (Ref 85), leaving these patients vulnerable to pernicious anemia.
Vitamin B12
Vitamin B12 is not produced naturally by our bodies, making this water-soluble nutrient essential to health in most individuals. Vitamin B12 plays an essential role in blood cell and nerve cell formation as well as DNA production and gastric acid production; plus its numerous other benefits including preventing anemia and improving cognitive performance.
Vitamin B12 can be obtained primarily through food sources such as meat, fish, poultry, dairy products and eggs; food-fortification of plant-based cereals and milks also contributes to providing this essential nutrient; however those following strict vegan diets may struggle meeting their requirements solely through dietary sources alone and may need oral supplements or injections for additional coverage.
Vitamin B12 deficiency causes symptoms such as anemia, which manifests with tiredness and weakness, dementia, confusion, tingling or numbness in the hands or feet, dementia and confusion among other symptoms. Research suggests supplementing with this vitamin may prevent and treat anemia while improving mood, memory and cognitive function in those suffering from dementia or depression.
Vitamin B12 helps to lower levels of homocysteine, an amino acid which promotes brain cell inflammation and may contribute to Alzheimer’s disease and other chronic conditions. According to studies, elevated homocysteine levels increase coronary heart disease risk. It can be caused by nutritional deficiencies, poor digestive function or certain medical conditions.
Vitamin B12 deficiency may result from taking medications to suppress stomach acid. This is most frequently seen among those taking proton pump inhibitors and H2 blockers for conditions like gastroesophageal reflux disease or peptic ulcers.
Although further research must be completed to ascertain how vitamin B12 affects mental health, studies indicate that this nutrient can provide relief from symptoms associated with depression and improve chances of recovery after depressive episodes, likely due to its role in serotonin production.
Vitamin B6
Vitamin B6 plays an integral part in over 4% of all enzymatic reactions. As an essential coenzyme it synthesises amino acids and proteins as well as supporting glycogen production and certain fat metabolism processes. Furthermore it assists with healthy red blood cell production as well as folic acid metabolism processes.
Vitamin B-12 is a water-soluble vitamin found in meat, fish, dairy products and eggs, though its importance should not generally be overemphasized in diets. Unfortunately, some individuals find it difficult to absorb enough from their food source; this can cause symptoms like tiredness, headaches and indigestion; however these typically improve once consumption increases.
Folate is well known for its role in helping to lower risk of some types of cancer and heart disease, while maintaining a healthy nervous system. You can find folate-rich food sources like breakfast cereals, bread, rice and pasta; or as a supplement such as Folic acid can be purchased, but research shows that humans can absorb folate through natural sources like liver, green leafy vegetables and nuts.
Vitamin B9, or folic acid, is another essential nutrient found in food sources like legumes, nuts, seeds, whole grains and dark green vegetables. As a water-soluble vitamin it plays an essential role in normal growth, development and reproduction – often overlooked due to alcohol consumption but studies have revealed certain groups may be at greater risk of deficiency such as those struggling to absorb enough through their diet.
Scientists have recently made the surprising discovery that certain plants can absorb vitamin B12. This discovery is made possible due to differences between plant and mammal absorption systems, enabling plants to take advantage of animal sources more effectively in order to absorb this essential nutrient.
Scientists from the University of Kent led by scientists trained Bacillus megaterium bacteria to produce all the components required for anaerobic production of vitamin B12. This enabled them to acquire all missing molecular pieces necessary to fully comprehend how this remarkable molecule is created.
Synthetic biology offers us a powerful way of harnessing this knowledge for medical treatment of pernicious anaemia or for fortifying crops so they contain sufficient amounts of B vitamin for daily intake, according to Eat Lancet and WWF Eat4Life recommendations.
Those taking prescription medicines or vaccines should inform both their doctor and pharmacist if any adverse reactions or risks have arisen from taking such treatments, so that they may monitor side effects and risks effectively. This will allow for proper assessment and management.
Vitamin B9
Vitamin B9, or folate, is an essential nutrient that plays an integral part in helping prevent neural tube defects in fetuses. Folate naturally occurs in leafy green vegetables and fruit while its synthetic form, folic acid, is added to processed food products due to being more stable than its natural form. Both forms are essential to health; however only folate can be converted to its active form methylfolate in the body.
Since humans produce their own folic acid, pregnant or trying to become pregnant individuals should take an additional daily dosage of 400 micrograms as advised by the Centers for Disease Control and Prevention (CDC). All adults should also consume enough folic acid in their diet to protect themselves against heart disease, stroke and other serious medical conditions; although genetic mutations may reduce methylfolate conversion.
New research may offer hope to alleviate this dilemma. Scientists from the University of Kent have discovered a particular bacteria strain capable of taking in and storing vitamin B12 from plants. Led by Professor Martin Warren and including researchers from John Innes Centre and LettUs Grow as well as students in year 11 and 12 classes at Sir Roger Manwood’s School in Sandwich, their team successfully created common garden cress seedlings capable of taking up this essential nutrient.
Researchers made this breakthrough by studying static crystal structures of bacterial protein complexes that capture and transport cobalamin. After conducting computer simulation, they then examined how these complexes captured and released cobalt atoms – this information could lead to strains of bacteria capable of manufacturing this vitamin in food production, providing safe and sustainable sources of vitamin production for humans.
As the world shifts towards plant-based diets, this research provides hope that B12 can be taken up and stored by plants – potentially placing vegetarians and vegans at risk of deficiency without supplementation or fortified foods containing B12. However, this also suggests a future where crops bred specifically for taking in and storing essential vitamins may become viable solutions.
B12 fortification has historically relied on animal products as raw materials for fortification, restricting availability of the essential nutrient in developing countries where access is restricted. But now there may be hope: breakthrough could use plant sources of B12 instead – making plant-based diets much more accessible while simultaneously addressing global deficiency levels and meeting nutritional requirements more effectively worldwide. Cell Chemical Biology published their research.
