Document Summary
Sensors for environmental changes and mechanisms for relaying this information to the cell. Each protein has its own unique defined structure that enables it to carry out a particular function. Amino acids are attached in a linear array to create the primary structure of the protein, known as a polypeptide. Amino acid residue - the remnants of an amino acid that has combined to form a peptide after the condensation reaction. The variable r group i. ii. iii. iv. Defines the property of each amino acid residue. The accumulated r groups define the properties of the entire polypeptide or protein. Properties of side chains that effect the conformation of the whole protein: Amino acids are classified into groups based upon solubility in water or polarity of the side chain. Solubility - a physical property of a molecule that can transiently bond with water through hydrogen bonding (it is thermodynamically favorable)
