Hence, the biochemical properties of the glucosides, so far as their hydrolysis by the enzymes which are present in many biological agents is concerned, depends wholly upon the molecular configuration of the glucose itself.
The actual process for these separations need not be discussed here, as it is given in detail in all standard text-books dealing with the methods of biochemical analysis.
It is sufficient now to call attention to the fact that these vital processes, in either plants or animals, are essentially chemical in character, and subject to study by the usual methods of biochemical investigations.
Bearing on the First Sugar of Photosynthesis," in Biochemical Journal, Vol.
Death is reduced to a biological event leading only to biochemical decomposition: No fun, no direct practical significance for others, except in the inheritance process, a market event for funeral parlors and pushy clergy.
Obviously, the language and literacy expected for the success of the biochemical reaction in the test tube is different from that involved in the constitution of the family.
It is possible to visualize molecular structures and simulate interactions of molecules in order to see how medicine affects the cells treated, the dynamics of mixing, chemical and biochemical reactions.

Biochemistry) A chemical compound which exhibits a synergistic effect on some biochemical or physiological action, in combination with another compound.
All classical enzymes are composed of protein, and control most of the biochemical transformations carrie dout in living cells.
You have undertaken a biochemical and medical survey for which you had neither the proper equipment nor the training qualifications, and you exposed your ship and your crewmates to an incredible risk in landing on such a planet.
Anatomically they were ordinary cellular creatures like you and me, and when we examined them we expected to find the same sort of biochemical reactions we'd find with any such creatures.
We're going to have to do a complete biochemical and medical survey before we can hope to do anything.
The principle that environments and life forms in the universe may be dissimilar, but that biochemical reactions are universal throughout creation," Dal said slowly.
Creatures may develop and adapt in different ways, but the basic biochemical reactions are the same.
However, this purely biochemical investigation cannot possibly give any information on which specific cells are synthesizing DNA.
Since metabolism is the sum of the biochemical reactions taking place in a living organism, it properly belongs to the field of investigation of biochemists.

Cell reproduction is the concern of both biochemists and morphologists[3] since it can be studied by either biochemical or morphological techniques.
The gene-action system is the series of biochemical events that regulate and direct all life processes by “transcription” of the genetic “information” contained in molecules of DNA.
The earliest biochemical studies employing radioactive isotopes go back to 1924, when George de Hevesy used natural radioactive lead to investigate a biological process.
This paper reports the results of studies involving morphological and biochemicalfeatures that I consider less sensitive to external environmental factors than are features which have been studied previously.
