Enzymes are biological catalysts, responsible for directing the flow of chemical reactions that is the basis for life.

Enzymes are remarkably specific, acting on only one or a few types of molecules (called “substrates” of…
As mentioned, the range of protein functions is enormous: from passive structural elements to active motor proteins and everything in between. What characteristics of proteins are required for them to carry out these functions? While these characteristics vary from protein to protein, there are some that can be found in most proteins. We will discuss…
It is often necessary to obtain a preparation containing protein molecules of only a single type (a “pure protein”); eg. for medical use or scientific study. With such preparations, one may determine 3D structure, binding affinities, or determine the amino acid sequence. Obtaining a pure protein is generally challenging because there are thousands of proteins…
Proteins are the largest and most varied class of biological molecules, and they show the greatest variety of structures. Many have intricate three-dimensional folding patterns that result in a compact form, but others do not fold up at all (“natively unstructured proteins”) and exist in random conformations.

More properly known as alpha-amino acids, their general structure is: Nineteen of the twenty amino acids have the same arrangement around the central alpha-carbon: a. an amino group, b. a carboxyl group, c. a hydrogen, and d. an R group (called the “side chain”) which differs for each amino acid. Recall that when 4 different…
The term “dogma” describes a doctrine or code of beliefs accepted as authoritative. The central dogma of biology refers to the way that genetic information is stored and retrieved in living cells. The classic relationship is DNA > RNA > Protein. Thus DNA functions as the information storage molecule, and this information is “read out”…
