Document Summary

Antibodies/complement proteins attack & destroy virus and bacteria. Receive chemical signals from outside and initiate response. Provides support for cells and tissues (hair, feathers) Moves substances across cell membrane and throughout body. Wanted to know if complex organic materials can be synthesized by simple molecules. These sparks represented electrical energy (lightning): the solution in the boiling flask began to turn pink, then deep red and cloudy. Hot mineral rich water, life may have begun here. Basis of life came from outer space or thorough contamination from atmosphere. Monomer amino acid; polymer peptides (proteins) Made of an amino group, a central carbon, a carboxyl functional group, and a r-group. Structural differ in the order in which the atoms are attached. Geometric differ in arrangement around a double bond. Can be trans: different side; cis: same side. Non-superimposable (think of hands); most amino acids have optical isomers. L-dopa is effective, but d-dopa is biologically inactive.
