In turn, animals provide much of the meat eaten by the human population, whether farmed or hunted, and until the arrival of mechanised transport, terrestrial mammals provided a large part of the power used for work and transport. A variety of living things serve as models in biological research, such as in genetics, and in drug testing.
Different non-human animals unwillingly help humans with creating medicine that can treat certain human diseases. For example, the anticoagulant properties of snake venom are key to potential medical use. These toxins can be used to treat heart disease, pulmonary embolism, and many other diseases, all of which may originate from blood clots.
All living things contain two types of large molecule, proteins and nucleic acids, the latter usually both DNA and RNA: these carry the information needed by each species, including the instructions to make each type of protein. The proteins, in turn, serve as the machinery which carries out the many chemical processes of life.

As a further example of WP:SYNTH, the Three types of use heading actually doesn't cite a single source that divides human use of living things into three: there are sources to support each of the three types, but not secondary sources as to why the types were broken down in that way.
These can be inorganic (for example, water and metal ions) or organic (for example, the amino acids, which are used to synthesize proteins). [7] The mechanisms used by cells to harness energy from their environment via chemical reactions are known as metabolism. The findings of biochemistry are applied primarily in medicine, nutrition and ...

The Psychopathology of Everyday Life. Everyday life is a key concept in cultural studies and is a specialized subject in the field of sociology.Some argue that, motivated by capitalism and industrialism's degrading effects on human existence and perception, writers and artists of the 19th century turned more towards self-reflection and the portrayal of everyday life represented in their ...
