Biochemistry Notes
Electrical potential guided by ions exists across the membrane of all body cells. Some cells, such as neuronal cells, cardiac muscle cells, etc., are excitable. The property is called excitability, … Read more
All organisms acquire nutrients from the environment to survive. Some nutrients operate as building blocks for the formation of biological material, whereas others, such as vitamins, control the course of … Read more
To characterize the nature of protein-protein interactions, three different models have been proposed. Emil Fischer first suggested the lock and key paradigm, which depicts inflexible interactions. Here, the shapes of … Read more
The movement of nitrogen between the atmosphere, biosphere, and geosphere in different forms is called the nitrogen cycle and is one of the major biogeochemical cycles. It may also be considered as the movement of nitrogen … Read more
Aerobic respiration refers to the concept of the breakdown of nutrients and the production of energy. Any organism, when consuming any nutritive material, the material goes through a series of … Read more
What are Lipids? Lipids are a group of diverse macromolecules consisting of fatty acids and their derivatives that are insoluble in water but soluble in organic solvents. Lipids consist of … Read more
Enzymes Definition An enzyme is a protein biomolecule that acts as a biocatalyst by regulating the rate of various metabolic reactions without itself being altered in the process. The name … Read more
Enzymes are biological catalysts. These are commonly proteins but also include RNA (ribozymes) molecules that catalyze chemical reactions by lowering the activation energy of a reaction. These are known to … Read more
Lipids and proteins are the major constituents of most plasma membranes which account for approximately 50-50% each by weight, with carbohydrate portion of glycolipids and glycoproteins comprising 5 to 10% … Read more
Pyrimidine is a heterocyclic aromatic compound composed of carbon and nitrogen atoms in a six-membered ring. Pyrimidine derivatives are also known as pyrimidine, which consists of three nitrogen bases along … Read more
