This is the first of a 4-volume module that is an introduction to
the study of cell chemistry and physiology. It is not intended to
be encyclopedic in nature but rather a general survey of the
subject with an emphasis on those topics that are central to an
understanding of cell biology and those that are certain to become
of increasing importance in the teaching of modern medicine.
We have followed what appeared to as to be the logical divisions of
the subject beginning with proteins. Allewell and her colleagues
stress the point that proteins fold spontaneously to form complex
three-dimensional structures and that some of them unfold with the
help of proteins called chaperones. Michaelis-Menten kinetics are
shown by Nelsestuen to describe the behaviour of enzymes in the
test tube. The formalism is particularly useful in the search for
agents of therapeutic value, as exemplified by methotrexate. Uptake
by mammalian cells of substrates and their metabolic conversions
are discussed by van der Vusse and Reneman. However, both Welch and
Savageau expound the view that the cell is not simply a bagful of
enzymes. The biologist is urged by Savageau to abandon
Michaelis-Menten formalism and apply the Power Law. The biologist
is also told that the approach to arriving at a theory of metabolic
control would have to be one of successive approximations requiring
the use of the computer. Information gained from comparative
biochemistry is shown by Storey and Brooks to have shed new light
on mechanisms of metabolic rate depression and freeze tolerance,
and to be applicable to organ transplantation technology. We are
reminded that enzyme adaptation is partly the result of the
presence of a hydrating shell of vicinal water that stabilises
conformation of the enzyme. Vicinal water, according to
Drost-Hausen and Singleton, lies adjacent to most solids and
protein interfaces. The kinks or breaks observed in the slope of
the Arrhenius plot are attributed to structural changes in vicinal
water. Regulation of cell volume is shown by Hempling to involve
regulation of cell water. It could be that the osmo-receptor or
volume detection system is a protein that links the cytoskeleton to
specific K and C1 channels. Additionally, it is interesting that
aquaporins, which are water channel-forming membrane proteins, are
now known to exist in both renal and extra-renal tissues. One of
the renal porins is affected by vasopressin.
We then pass on to protein synthesis (Rattan) and other important
topics including protein glycosylation (Hounsell), methylation
(Clarke), ADP-ribosylation (Pearson) and prenylation (Gelb). Among
the four types of lipids attached to membrane proteins are the
prenyl groups. Ford and Gross in their chapter on lipobiology drive
home the point that there is an accumulation of acyl carnitine and
lysophospholipids during myocardial infarction.
