Proteins are a diverse and abundant class of biomolecules, constituting more than 50% of the dry weight of cells. This diversity and abundance reflect the central role of proteins in virtually all aspects of cell structure and function. An extraordinary diversity of cellular activity is possible only because of the versatility inherent in proteins, each of which is specifically tailored to its biological role. The pattern by which each is tailored resides within the genetic information of cells, encoded in a specific sequence of nucleotide bases in DNA.

The third stage of binding is spreading. This involves cell reorganization and is dependent on metabolic inhibitors. The results are dramatic changes in cell structure and functional properties. 

A superb textbook on cell structure and function, covering the topics considered in this chapter, and a useful reference for many of the following chapters. 

This chapter begins with descriptions of the physical and chemical properties of water, to which ail aspects of cell structure and function are adapted. The attractive forces between water molecules and the slight tendency of water to ionize are of crucial importance to the structure and function of biomolecules. We review the topic of ionization in terms of equilibrium constants, pH,... 

Although many aspects of cell structure and function are influenced by pH, it is the catalytic activity of enzymes that is especially sensitive. Enzymes typically show maximal catalytic activity at a characteristic pH, called the pH optimum (Fig. 2-21). On either side of the optimum pH their catalytic activity often declines sharply. Thus, a small change in pH can make a large difference in the rate of some crucial enzyme-catalyzed reactions. Biological control of the pH of cells and body fluids is therefore of central importance in all aspects of metabolism and cellular activities.

Proteins are involved in cell structure and function as enzymes, determining the reactions that occur in cells. Thus, proteins, the products of genes, determine what cells look like and how they behave.

Proteins are made of amino acids arranged in chains joined by bonds that distinguish them as peptides. Proteins are essential parts of all plants and animals, participating in every process of cell structure and function. Some proteins are important for cell communication, immune responses, and life cycle. Proteins are also necessary in your diet, because the body cannot synthesize all the amino acids required for proteins to build cells, so you must obtain essential amino acids from proteins in your foods. Among superfruits particularly excellent as sources of amino acids and proteins are fig, goji, kiwifruit, seaberry, and guava. 

Water is the major component of all living organisms. It constitutes 60% or more of the weight of most living things, and it pervades all portions of every cell. It existed on our planet long before the appearance of any form of life. The evolution of life was doubtlessly shaped by physical and chemical properties of the aqueous environment. All aspects of living cells structure and function seem to be adapted to water-unique properties.
