Hormones. Fool.
Hormones
proteins are structural materials, energy sources, and chemical messengers.
Chemical messengers to send information move molecules in and out of cells
To function as enzymes (in chemical reactions).
No cell carries messages out of a cell. Hormones are considered to be messengers and as well as some proteins.
They can be activated by signaling molecules such as second messengers.

I believe they are called chemical messengers because of their function and the fact it is a chemical. They travel through the blood and target cells respond to hormones often because of their structure. I have read in a science book (McDougal Littell 's Human Biology) that they are called chemical messengers because they are made at one location and function at another.
Phospholipids have several different functions. They can act as anchors to cell proteins and can also act as protein messengers.

glands secrete chemical messengers called leucocytes?

What part of the membrane helps chemical reac
Membrane proteins serve a range of important purposes, such as helping cells to communicate, maintain their shape, carry out changes triggered by chemical messengers, and transport and share material. Hopefully this answered your question!
