Human cells possess implausibly complexed structure and made up of many compounds, among them a group of essential fats called phospholipids. A sophisticated and refined combination of essential phospholipids (EPL) comprises of phosphotidyl Choline (lecithin), phosphotidyl Serine, phosphotidylethanolamine, phosphotidylinositol, in…

As a Biology teacher, one of the things that I deem critical for students to leave my class knowing is the structural components (and their functions) of a eukaryotic cell. Eukaryotic cells are cells that have a nucleus and membrane…

Your body needs structure. Without it, we’re just a puddle of skin and blood. For the human body, this structure is provided in part by the skeleton. But our cells, the fundamental units from which we’re built, also require structure….

Biochemistry is that branch of chemistry that applies to chemical reactions in cells of organisms as big as a cow and as small as a bacterium. These biochemical reactions that take place inside the cells are amazingly organized and accurate. …

The cytoskeleton in human cells forms the backbone of all cells found in eukaryotes. This cytoskeleton helps the cell to maintain its shape, helps to protect the cell, functions in intracellular transport and allows for the cell to move using…

The mitochondria are organelles located with each cell. The mitochondria are bacillus shaped, or shaped like a drug capsule. In the fact that they are shaped like many common bacteria is not a coincidence. An important aspect of the mitochondria…
