Anabolic steroids are used as performance-enhancing drugs to increase the ability to do work and exercise by abnormally stimulating muscle growth, power, and aerobic capacity. This increased function comes with a cost of potentially life-threatening side effects.nfections are a common side effect of steroid abuse because of needle sharing and unsanitary techniques used when injecting the drugs into the skin. These are similar risks to IV drug abusers with increase potential to acquire blood-borne infections such as hepatitis and HIV/AIDS.
In water's hydrogen bonds, the hydrogen atom is covalently attached to the oxygen of a water molecule (492.2145 kJ mol-1 [350]) but has (optimally) an additional attraction (about 23.3 kJ mol-1 [168].
A molecule is two or more atoms linked by a chemical bond. Molecules can contain different types of bonds. If atoms are sharing electrons, then the bond between them is covalent. If an atom gives up an electron to another atom, then they have an ionic bond.Methane has four covalent bonds between carbon (C) and hydrogen (H). Chemical reactivity of molecules-tendency to break and form chemical bonds. 2  Biology of molecules-size and shape of molecules, and the nature of weak interactions with other molecules.
