Document Summary
Bio 102 chapter 3 protein structure and function. Describe the early experiments that lead to the theory of chemical evolution. Describe the properties of amino acids and understand the role of r-groups. Describe how amino acids form proteins through peptide bonds. Describe primary, secondary, and tertiary protein structure and how they relate to function. Describe the general properties of enzymes and enzyme kinetics. Chemical reaactions in atmosphere and ocean in ancient earth lead to formation of first complex carbon molecules called chemical evolution. Chemical evolution proposed in 1923 by alexander i. oparin hypothesis was published independently and size years later by j. Oparin-haldane proposal best understood as formal scientific theory. Theory can be broken into 4 steps **each step requires input of energy** Chemical evolution began with production of small organic compounds ie. formaldehyde (h2co) and hydrogen cyanide (hcn) & with h2, co2, ch4 and. 1953 stanley miller preformed breakthrough experiment in chemical evolution his question .
