Drug design frequently but not necessarily relies on computer modeling techniques. This type of modeling is sometimes referred to as computer-aided drug design. Finally, drug design that relies on the knowledge of the three-dimensional structure of the biomolecular target is known as structure-based drug design.
The most well known vitamin that the body canât produce and can only be gotten from animal foods, is Vitamin B12. Vitamin B12 is a water-soluble vitamin that is involved in the function of every cell in the body. It is tightly involved in the formation of blood and the function of the brain.
Vitamin B12 is naturally found in animal products, including fish, meat, poultry, eggs, milk, and milk products. Vitamin B12 is generally not present in plant foods, but fortified breakfast cereals are a readily available source of vitamin B12 with high bioavailability for vegetarians [5,13-15]. Some nutritional yeast products also contain vitamin B12.
