yeast is used to make bread!

Yeast are a large group of microorganisms, not chemical compounds.

Yeast infection is when there is an overgrowth of yeast, a naturally occurring fungus in the body, typically this will occur in womens vulva's or vagina's but they can occur anywhere and in anyone. There are various natural treatments, but for a yeast infection of the genitals just use an over-the-counter treatment such as a yeast infection cream.

Yeast is an example of migro-organisms of the fungi kingdom, used mostly for fermenting.

I think it is called Fermentation.
