Szószedet: simplicity (egyszerűség)

The relevant facts of biochemistry are many; the student approaching this subject for the
first time may occasionally feel overwhelmed. Perhaps the most encouraging development
in twentieth-century biology is the realization that, for all of the enormous diversity in
the biological world, there is a fundamental unity and simplicity to life. The organizing
principles, the biochemical unity, and the evolutionary perspective of diversity, provided
at the molecular level, will serve as helpful frames of reference for the study of

Although living organisms contain a very large number of different proteins and different
nucleic acids, a fundamental simplicity underlies their structure (Chapter 1). The simple
monomeric subunits from which all proteins and all nucleic acids are constructed are few
in number and identical in all living species. Proteins and nucleic acids are informational
macromolecules: each protein and each nucleic acid has a characteristic information-rich
subunit sequence (Fig. 3–15).

Polysaccharides built from only a single kind of unit, or from two different alternating
units, are not informational molecules in the same sense as are proteins and nucleic acids
(Fig. 3–15). However, complex polysaccharides made up of six or more different kinds of
sugars connected in branched chains do have the structural and stereochemical variety
that enables them to carry information recognizable by other macromolecules.
