Document Summary

Understanding chemical bonding between atoms and molecules is fundamental to understanding biochemistry: covalent bonds: strong bonds formed by the sharing of electrons between adjacent atoms, noncovalent interactions/bonds include. Uv light exposure has a high enough energy to break carbon-carbon and carbon- hydrogen bonds which bonds found in our bodies and cells. These bonds can be broken and affected by uv light: covalent bonds are stronger and more stable than noncovalent bonds. This is due to a higher amount of energy required to break covalent bonds as compared to noncovalent bonds. Hydrocarbons: chains or rings composed only of carbon and hydrogen, economically important, limited importance in biology due to the inability to be soluble in water. Electronegativity: the te(cid:374)de(cid:374)(cid:272)y of a(cid:374) ato(cid:373)"s a(cid:271)ility to attract an electron. If an atom is more electronegative than the other atom it is bound to, it will attract more electrons to itself and create a polar covalent bond.
