Naturally occurring means that people did not make it. Steel is not a mineral because it is an alloy produced by people. Inorganic means that the substance is not made by an organism. Wood and pearls are made by organisms and thus are not minerals.efinite chemical composition means that all occurrences of that mineral have a chemical composition that varies within a specific limited range. For example: the mineral halite (known as  rock salt  when it is mined) has a chemical composition of NaCl.
Cyanocobalamin injection is also sometimes used to treat methylmalonic aciduria (an inherited disease in which the body cannot break down protein) and is sometimes given to unborn babies to prevent methylmalonic aciduria after birth.
This doesnât only mean that cyanocobalamin is a less efficient way to supplement your vitamin B12 intake. You also face the problem of what happens to the cyanide group that is liberated during conversion into the âactiveâ (useful) form of B12 i.e. methylcobalamin.
