Penicillin is a type of antibiotic that is used to treat bacterial infections. It is one of the most widely used antibiotics in the world. Penicillin was discovered in 1928 by Alexander Fleming.

Vitamins are essential nutrients that the body needs to function properly. They are not produced by the body, so they must be obtained from food. Vitamins are divided into two groups: water-soluble vitamins and fat-soluble vitamins. Water-soluble vitamins are not stored in the body, so they must be consumed regularly. Fat-soluble vitamins can be stored in the body, so they do not need to be consumed as often.
Hormones are chemical messengers that are produced by glands in the body. They travel through the bloodstream and control many of the body’s functions, including growth, development, and metabolism.
