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 polar bond is formed when electrons are unequally shared between two atoms. Polar covalent bonding occurs because one atom has a stronger affinity for electrons than the other (yet not enough to pull the electrons away completely and form an ion). good example of a polar covalent bond is the hydrogen-oxygen bond in the water molecule. Water molecules contain two hydrogen atoms (pictured in red) bonded to one oxygen atom (blue). Oxygen, with six valence electrons, needs two additional electrons to complete its valence shell. Each hydrogen contains one electron.
