Why we get Fat AND Hungry | (Biology of Weight Gain & Low-Carb )

Why we get Fat AND Hungry | (Biology of Weight Gain & Low-Carb )

Growing up in Texas, I thought that the weight gain of people around me was just something that naturally happened. Though, I didn’t realize how big us Texans were getting until I saw Morgan Spurlock’s “Supersize Me!” and he mentioned how 5 of the fattest cities in America were in Texas. This was surprising, but …

Introduction to Biochemistry

Introduction to Biochemistry

Hey, it’s professor Dave, let’s talk about biochemistry. What is biochemistry? Is it biology? Is it chemistry? Well as you might guess, it’s sort of in-between, quite literally in terms of size. In the great panoply of the sciences, biochemistry sits right here. If we go smaller we get into small molecules made of just …

G-Protein Coupled Hormone Signal Transduction

G-Protein Coupled Hormone Signal Transduction

This animation depicts the surface view of a target cell and its interaction with a peptide hormone as a model to demonstrate g-protein coupled signal transduction in cells. Peptide hormones generally consist of short chains of amino acids. Because peptide hormones are often quite short, they lack a rigid three-dimensional conformation and are flexible. Peptide …
