Hormones
Cyclic AMP and calcium may be second messengers
Proteins have a very complicate chemical formula but not a "balanced chemical equation".
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.
It depends on what your definition of a chemical is. It is a molecule, and you can react it with other chemicals to form different products, so I would say it is a chemical. You can also synthesize proteins in labs, so that also would point to it being a chemical.
Yes proteins are built up from amino acids.
proteins are structural materials, energy sources, and chemical messengers.
Hormones. Fool.
Chemical messengers to send information move molecules in and out of cells
glands secrete chemical messengers called leucocytes?
Hormones
No cell carries messages out of a cell. Hormones are considered to be messengers and as well as some proteins.
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!
"hormones"
They can be activated by signaling molecules such as second messengers.
