Unit 1
Short Answer Question:
Atoms are the bases for biology, therefore types of interactions that can hold atoms together, molecular bonds, help determine formation, structure, and function of macromolecules, the essential to life, such as nucleic acids and proteins, and especially with their role in cell replication and the transmission of genetic information.
Essay:
In essence the structure of a biochemical entities determine its function. The properties of an organism and capabilities are soley based upon the structure, the chemicals it obtains as well as the interactions between them, types of bonding. In order to establish the function of an element in our environment we must observe its structure. Three observable examples are proteins, carbons, and water.
Proteins have a structure that consists of twenty different polymers which in turn result in their characteristics and capabilities. The specific properties of each kind of protein are largely dependent on the kind and sequence of the amino acids in it, yet many proteins include components other than amino acids. For example, some may have sugar molecules chemically attached. Other proteins may have lipid, or fat, molecules chemically bonded to them. Sugar and lipid molecules always are added when synthesis of the protein’s amino-acid chain is complete. Protein structures generally are described at four levels: primary, secondary, tertiary, and quaternary. Primary structure is simply the two-dimensional linear sequence of amino acids in the peptide chain. Secondary and tertiary structures both refer to the three-dimensional shape into which a protein chain folds. Finally, quaternary structure creates the way in which many protein chains relate with one another. For example, hemoglobin consists of four protein chains of two slightly different types, all attached to an iron atom.
