The endoplasmic reticulum (ER) is present in every eukaryotic cell except mature erythrocytes. It is a cell organelle with multiple functions. Without ER, the cell and thus the organism would not be viable. What is the endoplasmic reticulum? The endoplasmic reticulum (ER) is a very structurally rich cell organelle with a channel system of cavities. … Endoplasmic Reticulum: Structure, Function & Diseases
Definition Cells are the smallest, coherent units from which organs and tissues are built. Each cell is surrounded by a cell membrane, a barrier consisting of a special double layer of fat particles, the so-called lipid double layer. Lipid bilayers can be imagined as two fat films lying on top of each other, which cannot … Cell membrane
Structure of the cell membrane Cell membranes separate different areas from each other. To do this, they have to meet many different requirements: First of all, cell membranes are made up of a double layer of two fat films, which in turn are composed of individual fatty acids. The fatty acids consist of a water-soluble, … Structure of the cell membrane | Cell membrane
What are the components of the cell membrane? Basically, the cell membrane is composed of a phospholipid bilayer. Phospholipids are building blocks consisting of a water-loving, i.e. hydrophilic, head and a tail formed by 2 fatty acids. The part consisting of fatty acids is hydrophobic, which means that it repels water. In the bilayer of … What are the components of the cell membrane? | Cell membrane
Functions of the cell membrane As the complex structure of cell membranes already suggests, they have many different functions to fulfil, which can vary greatly depending on the type and localisation of the cell. On the one hand, membranes generally represent a barrier. A function that should not be underestimated. In our body, countless reactions … Functions of the cell membrane | Cell membrane
Differences to the cell membrane of bacteria – Penicillin The cell membrane of bacteria is hardly different from that of the human body. The big difference between the cells is the additional cell wall of the bacteria. The cell wall attaches itself outside the cell membrane and in this way stabilizes and protects the bacterium, … Differences to the cell membrane of bacteria – Penicillin | Cell membrane

Products Waxes for medical and pharmaceutical use are available in pharmacies and drugstores as pure substances in pharmacopoeia quality. Structure and properties Waxes are semisolid to solid, lipophilic and purified mixtures of substances, typically consisting mainly of esters of long-chain fatty acids with long-chain and aliphatic alcohols. They belong to the lipids. Rarely, they are … Grow
Introduction Fats, lipids and fatty acids are probably the most controversial energy suppliers in our diet. On the one hand they are responsible for diseases of civilization such as overweight and high cholesterol levels, on the other hand they are vital components of our diet. The quality of the individual fats is determined by the … Fats and Sport
Products Ethoxyquin was synthesized in the 1920s. In the late 1950s, ethoxyquin was first marketed by Monsanto (Santoquine). It is available as a chemical, among other products.
