In the Classroom
There is a version of teaching that transmits information. And there is another kind — rarer, more powerful — that changes how a person sees the world. Dr. Ray practiced the second kind.
His flagship course, Biological Sciences 170: Advanced Nutrition & Metabolism, was not for the faint of heart. Students had to earn their way in — prerequisites included biochemistry, a strong background in upper division science courses, and consent of Dr. Ray. Once admitted into the class, the student encounters a graduate-level study of the biochemistry and physiology of human nutrition: extensive study of carbohydrate, lipid, amino acid/protein, vitamin, mineral, water, alcohol, neurotransmitter, nucleotide, and hormone metabolism. A sample of what students will also critically examine are the interrelationships between the Krebs cycle (tricarboxylic acid cycle) and oxidative phosphorylation (electron transport system), which defines the control of cellular respiration and ultimately the rate of substrate utilization for cellular energy (ATP) production. The full elegant machinery of life.
“Students described it as the hardest and most comprehensive university class they ever loved.”
Dr. Ray was recognized with a Meritorious Superior Teaching Award by the University for his 28 years of teaching at the University. Dr. Ray was also selected as one of only five national faculty panelists at UC Berkeley's Annual Faculty Teaching Symposium. He also presented over 300 hours of live televised instruction and won the Cable Television Educator Award three consecutive years.

Original Research
University of California at Davis — The Lab That Shaped Everything
Dr. Ray's doctoral scientific research was conducted at the University of California at Davis in the laboratory of Dr. Richard A. Freedland, Chair of Molecular Sciences, School of Veterinary Medicine, UC Davis (No. 1 rated school of veterinary medicine in the world). Dr. Ray's lab colleague Dr. Roger Newton went on to develop Lipitor, one of the most prescribed cholesterol-lowering drugs in history. Dr. Newton also developed Nexletol and Nexlizet, used to lower blood cholesterol levels. Dr. Haring's and Dr. Newton's laboratory research methods were developed in Dr. Krebs' laboratory at the University of Oxford, England and brought back by Dr. Freedland — who personally worked with Dr. Krebs in his laboratory — so that his Ph.D. candidates could use the same laboratory techniques in their research.
Alcohol Metabolism
Dr. Ray's dissertation research focused on the biochemical and physiological mechanisms controlling ethanol (alcohol) oxidation. This work formed the scientific backbone of Shattering Myths & Mysteries of Alcohol — endorsed by Dr. George D. Lundberg, M.D., Editor-in-Chief of the Journal of the American Medical Association (JAMA).
The Metabolic Pathways
The Beautiful Complexity of Life
The following commentary and metabolic pathway diagrams are presented in Dr. Ray's own words — exactly as he has taught them for decades.
Aside from the few remarks below, no significant effort is made to explain the importance of these metabolic pathways. I hope the few comments provided, however, conjure up some curiosity.
The first pathway, shown below, describes the catabolism of carbohydrate (glucose) to lactate via anerobic glycolysis, which by definition occurs under anaerobic conditions. The next time you exercise and feel that “burn,” you will begin to appreciate this pathway and the reason why heart rate and respiration increase with muscle lactate production. Essentially, your lungs and heart are trying their best to deliver and replenish the additional oxygen used and needed during intense muscular activity. I have a great section on this material in Smart Weight Loss. Reading Smart Weight Loss is a much easier way to understand nutrition and exercise metabolism without pronouncing funny names and staring at strange diagrams. This is one of the reasons I wrote Smart Weight Loss.
The next metabolic pathway, shown below, is essential for the synthesis of urea (ureagenesis) from various nitrogen sources. Not a pathway we spend too much time thinking about on a daily basis until it is time to appreciate the vital role our kidneys and liver play in the elimination of nitrogen in the form of urea.
The next metabolic pathway, shown below, describes the oxidation (burning) of fatty acids (fat). The best way to lose extra or unwanted adipose tissue (fat) is to do more of the following:
The diagram below depicts the basic inter-relationship between amino acids (protein), triglycerides (fat), and carbohydrates (sugars). Memorizing metabolic pathways, like the one below, is the best way to start seeing the overall “picture” up close.
You will appreciate the next pathway, shown below, when you are unfed, on a caloric restricted diet, or when you are generating glucose from lactic acid (lactate) during bouts of anaerobic activity. Carbon flux to glucose from amino acids (derived from protein degradation) are not shown in this diagram. The following pathway, however, describes the metabolic events when your liver is told (“instructed”) to make glucose (sugar) via a process called gluconeogenesis. Start looking for “lactate” near the bottom of the diagram (just outside the mitochondrion) and then carefully follow the arrows to the top of the diagram to locate “glucose.” Note that the cytosolic enzyme “Pyruvate Kinase” catalyzes an irreversible (unidirectional) reaction between phosphoenol pyruvate (PEP) and pyruvate. Not much room here to discuss why it happens the way it does, but note that pyruvate must enter the mitochondrion to eventually get metabolized to phosphoenol pyruvate (PEP). In an unfed state, all reactions between phosphoenol pyruvate (PEP) and glucose in liver tissue are reversible. Do you see where the sugar “glucose” is produced and how we got there from “lactate?” The topic of gluconeogenesis gets very interesting when the regulatory (hormonal/enzymes) details are presented. Also look for pyruvic acid (pyruvate) and notice that pyruvate is just one step closer to glucose than lactate. Remember, lactate used for glucose production in liver (hepatic) tissue is generated in skeletal muscle tissue from anaerobic glycolysis, ie., “burning” or oxidizing glucose as a source of fuel when muscle cells are running a bit low on oxygen during intense physical activities. Although the steps are not shown or mentioned in the diagram below, certain amino acids generated from protein degradation can be used to make pyruvate and Citric Acid Cycle intermediates after they have been stripped (deaminated) of their nitrogen group. Simply, this means our bodies will increase rates of protein degradation in order to make glucose (gluconeogenesis) during periods of food restriction. Think simple. Does it make sense to try to keep the sugar (glucose) level from falling into the hypoglycemic (low) range during an intentional or unintentional restriction of food intake? Yes! The liver is pretty smart at times!
The next metabolic pathway, shown below, describes the production of ketone bodies (ketogenesis) from fatty acids. Look for “acetone.” It is the ketone body that gives you the “bad breath” syndrome when blood insulin levels are low. Seriously, it is critical that the liver makes ketone bodies whenever blood insulin levels are low. You have a healthy curiosity if you are wondering why?
The last diagram, shown below, pretty much explains why I took all the big words and complicated diagrams out of my Smart Weight Loss book. I have always found it fascinating that there are so many different ways to essentially make the same point.
The diagrams above are excerpts from the Review of Physiological Chemistry.
