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.

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.
