Concept of hybrid molecules:
When double strand DNA is steamed to a temperature
exceed the melting temperature (Tm), it will separate
into 2 single strands DNA due to breaks of H bonds. If
the reaction temperature is then decreased slowly plus
other appropriate experimental conditions, these
ssDNA will pair again. This phenomenon is called the
hybridization of molecules.
Characteristic of the hybrid molecules: Specificity, the
re-pairing occurs only between two complementary
he characterization of individual molecules has been a scientifically attractive and challenging task for decades, and remains so today. New technological developments have facilitated great progress in our understanding of the structure and behavior of single atoms and molecules in various environments.
This book presents basic and advanced principles underlying the multivalent
interactions that are prevalent in biological systems. To illustrate important or
complex concepts, the book provides up-to-date examples of synthetic multivalent
molecules, their design, and their biological benefits. Functional roles
displayed by such molecules of both natural and synthetic origin are well
documented in biology, where they exert unique and crucial activities at a
level not readily achievable by monovalent molecules.
After studying this chapter, you should be able to accomplish the following outcomes: List the features of carbon that result in the diversity of organic molecules, tell how macromolecules are assembled and disassembled, name the most common 5 and 6-carbon sugars and give a function for each, compare the structures of starch, glycogen, and cellulose and give a function for each,...
Molecules, small structures composed of atoms, are essential substances for lives.
However, we didn’t have the clear answer to the following questions until the 1920s:
why molecules can exist in stable as rigid networks between atoms, and why
molecules can change into different types of molecules. The most important event for
solving the puzzles is the discovery of the quantum mechanics. Quantum mechanics is
the theory for small particles such as electrons and nuclei, and was applied to
hydrogen molecule by Heitler and London at 1927.
Metabolomics is the scientific study of chemical processes involving metabolites. Specifically, metabolomics is the "systematic study of the unique chemical fingerprints that specific cellular processes leave behind", the study of their small-molecule metabolite profiles. The metabolome represents the collection of all metabolites in a biological cell, tissue, organ or organism, which are the end products of cellular processes.
This course of lectures is devoted to protein physics, i.e., to the overall topics of
structure, self-organization and function of protein molecules.
The course is based on lectures given by us (earlier by O.B.P., and later by A.V.F.)
first at Moscow PhysTech Institute and then at Pushchino State University and the
Pushchino Branch of MoscowState University. Initially, our students were physicists,
then mainly biologists with some chemists.
There is hardly any book that aims at solving problems typically encountered in the
laser field, and this book intends to fill the void. Following some initial exercises related to
general aspects in laser physics (Chapt. I), the subsequent problems are organized along the
following topics: (i) Interaction of radiation with matter either made of atoms or ions,
weakly interacting with surrounding species, or made of more complicated elements such
as molecules or semiconductors (Chapters 2 and 3). (ii) Wave propagation in optical media
and optical resonators (Chapters 4 and 5)....

Twenty-five years ago, Georges Köhler and César Milstein invented a means of
cloning individual antibodies, thus opening up the way for tremendous advances in the
fields of cell biology and clinical diagnostics (1). However, in spite of their early
promise, monoclonal antibodies (MAbs) were largely unsuccessful as therapeutic
reagents resulting from insufficient activation of human effector functions and
immune reactions against proteins of murine origin.
