The answer is Cx,(H2O)y (It could be associated with other elements).
From the point of view of chemistry, the characteristic of organic matter is to be organized from water and carbonaceous materials (Cx, (H2O) y), its properties in combination with the few elements with which it is abundantly associates in nature (hydrogen, oxygen, nitrogen, phosphorus, sulfur, etc.).
Organic chemistry, then biochemistry, developed through the study of the multitude of these organic compounds with particular properties and behaviors, in comparison with inorganic chemistry.
