CHEM 265 Biochemistry I • 5 Cr.

Department

Division

Description:

The first in a two-quarter sequence for science majors and for students interested in careers in pharmacy, dentistry, medicine, veterinary medicine and medical technology. Topics include protein structure and function; carbohydrates and their metabolism, electron transport processes and some of the major metabolic pathways. Prerequisite: BIOL& 211 and CHEM& 261.

Outcomes:

  • Protein structure and function
  • • Draw the structure of amino acids at a given pH and discuss the chemistry of the peptide bond
  • • Describe all four levels of protein structure and protein folding
  • • Describe and recognize different protein purification, analysis and sequencing strategies
  • • Describe the biochemical action of muscles, myofibrils and myosin-actin
  • Enzymatic catalysis, kinetics, inhibition and control
  • • Define enzyme, substrate, cofactors, allosteric, enzyme catalysis and enzyme inhibition

  • • Perform calculations for enzyme kinetics
  • Carbohydrates
  • • Describe the chemical structure of carbohydrates
  • • Describe lactose, sucrose, cellulose, and the “glycogens” in terms of structure and function
  • Introduction to metabolism
  • • Give an overview of metabolism in terms of free energy, nutrition, thermodynamics, and flux
  • • Explain the concept of a high-energy compound such as ATP, acetyl-CoA
  • • Describe how oxidation-reduction plays a role in metabolism
