Because of this symmetrical geometry, CCl 4 is non-polar. Methane gas has the same structure, making carbon tetrachloride a halomethane. As a solvent, it is well suited to dissolving other non-polar compounds, fats, and oils. It can also dissolve iodine.
The best sources of Vitamin B 12 include: eggs, milk, cheese, milk products, meat, fish, shellfish and poultry. Some soy and rice beverages as well as soy based meat substitutes are fortified with vitamin B12. To see if a product contains vitamin B 12 check the Nutrition Facts on the food label.
There is also evidence linking B12 deficiency to Alzheimerâs Disease, which is the most common cause of dementia in Western countries (4, 5). The only good food sources of B12 are animal foods like meat, fish and eggs. A deficiency is widespread among vegans and vegetarians, who avoid these foods. In one study, 92% of vegans and 47% of lacto-ovo vegetarians were deficient in this critical brain nutrient (6).
