5.3.1 Allosteric regulation
In this unit we explore how proteins are the 'doers' of the cell. They are huge in number and variety and diverse in structure and function, serving both the structural building blocks and the functional machinery of the cell. Just about every process in every cell requires specific proteins. The basic principles of protein structure and function which are reviewed in this unit are crucial to understanding how proteins perform their various roles.

Understanding cardiovascular diseases
Your heart beats around 100,000 times every day and, in that time, pumps about 23,000 litres of blood around your body. But what happens when it doesn’t work as well as it should? This unit explains what happens in cardiovascular disease, when the heart’s performance is affected, how the normal function of blood vessels is impaired, and what treatments are available. Whether you are a patient, relative, friend or healthcare professional, you will find the unit interesting.

Bioengineering at MIT: Building Bridges Between the Sciences, Engineering and Health Care (Part Two
Glycomics, the study of sugars’ role in living systems, is a relative newcomer to the revolution in molecular biology. In fact, Ram Sasisekharan remembers how colleagues told him “not to work on carbohydrates -- that it was useless.” But his research has shown that glycans, observed as long chains or intricat
