Document Summary
* one or more atoms bond to each other forming a carbon backbone which atoms are attached. * has a capacity to form long chains of large molecules by carbon bonds. * share electrons with elements like o,cn,s and p => this tetra valence makes large complex molecules possible. * carbon atoms link to each other forming carbon skeleton. * three bonds between carbons will repel each other to both negative charge and thus causes it to be unstable. Steroid hormones: testosterone - male hormone, estrogen - female hormone. * carbon skeleton are identical, functional group differ then interact with different targets in the body. Five functional group: hydroxyl - o-h, phosphate - o. Oh: carbonyl - o, amino - h - n - h, carboxyl - h - o - c = o. * big and made up of hundreds of molecules. * small building blocks (monomers) covalently bond to form big molecules called polymers.
