About this title

Synopsis

Explore how early dialysis experiments revealed what molecules pass through membranes and how enzymes behave when separated from their surroundings.

This book surveys laboratory studies on diffusion, dialysis, and enzyme activity, showing how substances like urea, glycerol, amino acids, and proteins move across membranes under different conditions.

Through a series of experiments, it discusses the limits of dialysis with collodion membranes, the fate of enzymes such as pepsin, trypsin, and catalase, and how activity can change after dialysis. It also presents debates on how urine is formed, comparing mechanical and secretory theories with data from diffusion and diffusion-like processes.

Examples of diffusion rates for glycerol, urea, glycocoll, alanine, amino acids, and peptone.
Observations on enzyme stability and activity after dialysis, including catalase and ptyalin (salivary amylase).
Discussion of experimental setups, membranes, and preservation methods used in these studies.
A framing of how these findings relate to broader theories of urinary secretion.

Ideal for readers interested in physiology, biochemistry, and the history of laboratory techniques in enzyme research.

Store Description

**Please note our transit times are from the date of dispatch.** We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first purchase with us, or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
