  Biochemistry News In 2017 Biochemistry  is also known as biological chemistry. It is the study of chemical processes within the living organisms. In this article, we will explore all breakthroughs, innovations and Nobel prize winners in Biochemistry for the year 2017. 1. Moosy 32Enose – An Electronic Nose The first and most important biochemistry news in 2017 is  Moosy 32Enose . Researchers developed a technology that can help sniff disease, called the  Moosy 32eNose . This new device can help differentiate between patients with Crohn’s disease and ulcerative colitis. In the future, the electronic nose could be used to detect pancreatic cancer or to detect microbial contamination of water. 2. The Hybrid-SOEC System A team of scientists at the Ulsan National Institute of science and technology (UNIST) has developed a new system for efficient hydrogen production. This new technology called the Hybrid-SOEC system produces hydrogen in a highly efficient and cost-effect...

 Nucleic acids Nucleic acids are essential biomolecules found in all living organisms. They play a crucial role in storing, transmitting, and expressing genetic information. Types of Nucleic Acids: 1. DNA (Deoxyribonucleic acid) 2. RNA (Ribonucleic acid) Structure of Nucleic Acids: Nucleic acids are composed of: 1. Nitrogenous bases (Adenine, Guanine, Cytosine, Thymine/Uracil) 2. Sugar molecules (Deoxyribose/Ribose) 3. Phosphate groups Functions of Nucleic Acids: 1. DNA:     - Stores genetic information     - Transfers genetic traits to offspring     - Provides instructions for protein synthesis 2. RNA:     - Transfers genetic information from DNA to ribosomes     - Participates in protein synthesis     - Regulates gene expression Types of RNA: 1. Messenger RNA (mRNA) 2. Transfer RNA (tRNA) 3. Ribosomal RNA (rRNA) 4. Small nuclear RNA (snRNA) 5. MicroRNA (miRNA) Importance of Nucleic Acids: 1. Genetic inheritance 2. Protei...

   Vitamins Vitamins are   organic substances that are essential for the body to function properly and stay healthy .   They are needed in small quantities and can be obtained from plant and animal foods, dietary supplements, or the body itself.   There are 13 essential vitamins, including: Vitamin A Vitamin C Vitamin D Vitamin E Vitamin K Vitamin B1 (thiamine) Vitamin B2 (riboflavin) Vitamin B3 (niacin) Vitamin B6 (pyridoxine) Vitamin B12 (cyanocobalamin) Pantothenic acid (B5) Biotin (B7) Vitamins can cause side effects, especially at high doses, including: Bad taste in your mouth, Stomach pain, Nausea, Vomiting, Diarrhea, and Constipation.   You should talk with a doctor before taking vitamins

  Biomolecules Biomolecules include both micromolecules, e.g. amino acids, nitrogenous bases, fatty acids, sugar, etc. and macromolecules, such as carbohydrates, proteins, lipids and nucleic acids. Living organisms are made up of organic as well as inorganic substances. For analysing the organic constituents of living tissue, we mix it with CCl 3 COOH (Trichloroacetic acid) and make a slurry by grinding. We get two fractions: Acid soluble fraction- Organic micromolecules (biomolecules) (mol wt. 18-800 Da) and inorganic compounds, e.g. phosphate, sulphate, etc. It mostly accounts for the cytoplasm Acid insoluble fraction- Polymeric macromolecules (mol wt. >10 thousand Da) and also lipid (a component of the cell membrane and form water-insoluble vesicles on fragmentation) The inorganic constituents can be estimated by analysing the ash formed after burning a tissue completely. All the macromolecules are homo or heteropolymers of various simple compounds. Protein- Polymer of amino ...
