Document Summary
When he analyzed samples from the mini-ocean, he found hydrogen cyanide (hcn)and formaldehyde (h2co) these are key compounds in chemical evolution because they are required for reactions that lead to the synthesis of more complex molecules. The sparks and heating had led to the synthesis of compounds that are building blocks of proteins: amino acids. Many other researchers pointed out that because volcanism would have been common as the. Amino acids have a c atom (c atom has a valence of 4) that forms bonds to: The combination of these is key to how these molecules behave: In water at ph 7, the concentration of protons causes the amino group to act as a base. The charges on these functional groups are important for 2 reason: they help amino acids stay in solution, where they can interact with one another and with other solutes, they alter amino acid chemical reactivity.
