Novel coronavirus (2019-nCoV)
Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans. https://youtu.be/HFi6rvuyRtk Free Certification Academy Europe presents…
Sign Language
Sign languages (also known as signed languages) are languages that use the visual-manual modality to convey meaning. Sign languages are expressed through manual articulations in combination with non-manual elements. Sign languages are full-fledged natural languages with their own grammar and lexicon. https://youtu.be/LUrPlhb8YB0 Free Certification Academy Europe presents high-quality formal diplomas, certificates and e-certificates which are formal proof and recognition of…
The Chemistry of Carbohydrates
Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules. They are often called sugars. Other carbohydrate molecules are very large (polysaccharides such as starch and cellulose). https://youtu.be/8Q4toJyrgKU Carbohydrates are: a source of energy for…
Triacylglycerol Metabolism
Triacylglycerides possess a glycerol backbone, derived from either glyceraldehyde-3-phosphate or dihydroxyacetone phosphate produced in glycolysis. Esterified to the glycerol backbone are three fatty acid chains, which consist of nonpolar hydrocarbon tails that vary in their length as well as the degree of saturation. https://youtu.be/DF4hQveQ9g8 Triacylglycerol occurs in human metabolism in two roles, namely (a)as…
Cholesterol Metabolism
Cholesterol metabolism in humans is complex. Cholesterol is either supplied from the diet (exogenous) or synthesized de novo by many cells of the body (endogenous). The major factors in the diet that may increase the blood cholesterol level are high intakes of cholesterol itself, or of saturated fats and excessive calories. The liver is one of the major…
Metabolic Regulation
Metabolic regulation is the physiological mechanism by which the body takes in nutrients and delivers energy as required. Metabolic regulation works ultimately at a molecular level, mainly by modulation of enzyme activities that function together as a whole system to sense the balance of energy coming in and energy required. The different organs in the…
Basic Knowledge of RNA
Ribonucleic acid, or RNA is one of the three major biological macromolecules that are essential for all known forms of life (along with DNA and proteins). A central tenet of molecular biology states that the flow of genetic information in a cell is from DNA through RNA to proteins: “DNA makes RNA makes protein”. Proteins are…
