Document Summary

Structures of the major compounds of the body. Organic compounds are made up of the atoms: Car(cid:271)o(cid:374) (cid:272)a(cid:374) (cid:373)ake up to (cid:1008) (cid:271)o(cid:374)ds, si(cid:374)gle or dou(cid:271)le (cid:271)o(cid:374)ds (cid:271)etwee(cid:374) c"s for(cid:373) the (cid:271)a(cid:272)k(cid:271)o(cid:374)e of compounds. If the compound is a straight chain it is called aliphatic. Simplest molecule is methane where c bonds to 4 hydrogen.

The other method uses greek letters to count from the carbon next to the most oxidized. This molecule can be called 3-hydroxybutyrate or - hydroxybutyrate. Carbons also bond to form ring structures in many compounds.
