Biochemistry

BCHM461 – Biochemistry I

Prerequisite: Minimum grade of C- in CHEM 271 and CHEM 272 or CHEM 276 and CHEM 277. Credit only granted for: BCHM 461 or BCHM 463.
The study of the structures, chemical properties, and chemical behavior of the molecules that are essential for life. Biochemistry 461 is the first of a three-semester series of courses that cover all of the basic aspects of the subject. We will cover in this course the four major classes of biological molecules: proteins and enzymes, nucleic acids, carbohydrates, and lipids.

The course content can be summarized as:

(1) the atomic structures and chemical properties of the organic molecules of biology; (2) how the chemical properties determine the three-dimensional structures of these molecules; and (3) how the structure and chemical properties together enable these molecules to carry out their biological functions.

BCHM462:

Prerequisite: Minimum grade of C- in BCHM 461. Credit only granted for: BCHM 462 or BCHM 463.

Covers metabolism in all of its chemical and biological intricacy. The course covers the pathways by which nutrients in food are broken down to provide energy and small molecule building blocks, and how those building blocks and energy are used to construct the biological molecules that are characteristic of the particular organism. The focus will be on metabolism in humans, but important pathways or interesting variations that are found in plants, yeast, and bacteria will also be discussed.

The important concepts that appear throughout the course are:

1) the organic chemistry of biological systems;

2) how organisms extract energy from food and the environment, and how they use the energy for biosynthesis;

3) the chemical mechanisms by which enzymes catalyze biological reactions;

4) the functions of co-enzymes derived from vitamins;

5) mechanisms for regulating the catalytic activity of individual enzymes, the flux through metabolic pathways, and the overall metabolism in an organism;

6) the medical relevance, including diseases that arise due to defects in metabolism, and drugs that intervene at specific metabolic steps.

Biochemistry 462 depends critically on concepts from previous courses:

1) General Chemistry (chemical equilibria; kinetics; basic thermodynamics),

2) Organic Chemistry (structures, nomenclature, and the chemical mechanisms of some types of reactions),

3) Biochemistry 461 (structures of amino acids, carbohydrates, lipids, and nucleotides; protein structure; properties of enzymes and catalytic strategies; allostery), and

4) Cell Biology (cell structure and organization; organelles; membrane structure, and transport across membranes). The most relevant aspects of these topics will be reviewed briefly, as necessary.

BCHM463:

Prerequisite: Minimum grade of C- in CHEM 271 and CHEM 272 or CHEM 276 and CHEM 277 or CHEM 271 and CHEM 272.  Credit only granted for: BCHM 461, BCHM 462 or BCHM 463.
