Biological Membranes was the subject of an earlier blog post. Charles Tanford, “The Hydrophobic Effect: Formation of Micelles and Biological Membranes”, 1st Edition, was published in 1973. The “Singer-Nicolson” biological membrane model of 1972, generated interest in the “Hydrophobic Effect”. The “effect” is the strong attraction of water for itself, and weak hydrocarbon attraction. The … Continue reading Charles Tanford, "The Hydrophobic Effect: Formation of Micelles and Biological Membranes, 2nd Edition, 1980.
The Singer-Nicolson model in biochemistry is second only to the Watson-Crick model in importance. The cell organelles of the two models: 1. cell membranes, and 2. genetic chromosomes are fundamental cellular structures. In the diagram above, proteins are large objects in the lipid fluid. The years 1953 and 1972 gave biochemistry these new idea models. Continue reading S. Singer & G. Nicolson, “The Fluid Mosaic Model of the Structure of Cell Membranes”, SCIENCE, 1972, volume 175, pages 720-731.
Here is the use of a radioactive isotope in metabolomics’ by Joseph Katz. Otto Warburg’s decades earlier research was foundational metabolism study. Carbon-14, here used by Joseph Katz was the next generation of metabolomics. Radiology is an area of Medicine that has used Glucose-Carbon-14 in studies of Neurology. The ABOVE photograph shows blood vessels … Continue reading Joseph Katz, "The use of Glucose Carbon-14 in the Study of the Pathways of Glucose Metabolism in Mammalian Tissues".
There are 15 cell types in Porifera(sponges). This schematic drawing shows the typical cell type arrangement of a sponge. Poriferans are filter feeders, and amorphously unembryonic. Sponges are the foundation organisms of the Animal kingdom taxon. Continue reading Kitchen Sponge (poriferan) cell types.
Cellular respiration depicted above is the combination of three biochemical pathways. These pathways are 1. Glycolysis 2. Kreb’s Citrate Cycle and 3. The Electron Transport Chain. Continue reading Cellular Respiration: Glycolysis, Citric Acid Cycle & Electron Transport Chain.
