Protein or the physical region of the protein that participates in chemical catalysis. In solution proteins also undergo variation in structure through thermal vibration and the collision with other molecules. Proteins can be informally divided into three main classes, which correlate with typical tertiary structures: globular proteins, fibrous proteins, and membrane proteins. Almost all globular proteins are soluble and many are enzymes. Fibrous proteins are often structural, such as collagen, the major component of connective tissue, or keratin, the protein component of hair and nails. Membrane proteins often serve as receptors or provide channels for polar or charged molecules to pass
In the Name of the Brother extraordinary things discovered in the real world are likely to be "studied to death." The name of the character Greg Mendell is similar to that of Gregor Mendel, who is known as the father of modern genetics. It is not known if this reference is deliberate, or what its significance is.
