Unformatted text preview: Proteins Vary Greatly in Size, Shape, and Function proteins can be grouped into several broad, functional categories structural proteins: provide structural rigidity to the cell transport proteins: control passage of substances across cell membranes regulatory proteins: act as sensors/switches to control protein activity/gene function signaling proteins: transmit external signals inside the cell motor proteins: produce movement Proteins: polymers of 20 different amino acids characteristic structure: a central C atom (C ) bound to 4 different chemical groups an amino group (NH 2 ) a carboxyl group (COOH) a H atom a variable group ( side chain or R group ) carbon of all amino acids (except glycine) is asymmetric exist as stereoisomers (D and L forms) usually only the L forms are found in proteins Stereoisomeric Amino Acid Structures chemical properties are the same, yet biological activities are distinct to understand proteins, you must understand the amino acids...
