how Vitamin A, B, and C work


how Vitamin A, B, and C work

In: Biology

Digestion is the process of using enzymes to break down foods into component proteins.
Vitamins are enzymes that your body does not produce on its own.
Vitamin C in particular is key to making proteins used to create antibodies.

Can’t really ELI5 the question you way you asked since you specifically asked a biochem question about several very different things at once.

But guessing what you’re actually asking, what they do/why they’re needed, they are gears that play a part in your bodies machinery. They all have very different roles and anybody explaining them in a few sentences is compressing what they do too much – each vitamin literally has hundreds, thousands of different (sometimes contradictory) individual functions let alone the byproducts produced after these vitamins go through their first use.

Something is called a vitamin when you must eat it in it’s exact form (or one or two steps away) in your diet. If your body is able to make it from several different things, then it’s not considered to be a vitamin.

Lutein for example is required by your body but not considered to be a vitamin because your body is able to make it from a few different sources, only under pretty severe circumstances would it in theory be necessary and at that point you’re more than likely starving and need a bunch of other things too.

You are asking about 10 different vitamins here, all with different functions (there are 8 B vitamins). They key thing they share in common is that your body needs to convert some chemicals to other chemicals. It has enzymes that do this. Some of those enzymes need vitamins in order to function.

For example, your body needs to make a molecule called collagen. One of the enzymes in the collagen making process needs vitamin C in order to work properly. Without vitamin C, you end up with a disease called scurvy.

That’s pretty much the only function of vitamins. They just serve as support for a handful of enzymes in your body. One vitamin might only be involved with 3-4 enzymes in your whole body. But those 3 or 4 enzymes are key steps in 3-4 necessary processes. Without vitamins, you can get really sick and even die.
