Polysaccharide

many higher organisms in the food chain. It is one of the many biological molecules present in plants and needed by animals. Biological molecules are macromolecules composed of many monomers (polymer) connected through a covalent bond forming polysaccharides, proteins, and nucleic acids (Table 1). They have specific, characteristic three-dimensional shapes that depend on the structure, properties, and sequence of their monomers important for their biological functioning and their interactions…

2.2.3. Azoles. Its mode of action, therapeutic properties, and resistance mechanisms developed by fungi and also by pharmaceutical companies, who get involve in enhancing its efficacy studied more. Hence it is mostly used antifungal agent in clinical practice. Azoles are two types i.e. imidazoles contain two nitrogen atoms, and the triazoles contain three nitrogen atoms which was classified according to number of nitrogen atoms presents in this cyclic organic molecules. Azole drugs target the…

Structure of Glucose Introduction to Glucose: Glucose, a rich source of energy for living organisms, is produced by the photosynthesis of water and carbon dioxide. Living organisms take in food and obtain energy by the chemical and mechanical breakdown of glucose. Glucose is a simplest carbohydrate, belongs to the monosaccharide category of sugars. More complex carbohydrates usually arise from the linked glucose units (Spencer et. al, 2010). Chemical composition of glucose: Being the simplest…

1. Pyrimidines are heterocyclic aromatic amines which, together with purines, form nucleotides. Nucleotides are the building blocks of nucleic acids, the basic structural component of DNA and RNA. The pyrimidines in DNA are cytosine and thymine, and in RNA uracil replaces thymine (Bettelheim, Brown, Campbell, Farrell & Torres, 2013). 
DNA and RNA are found in the nuclei of all cells and their job is to transmit the information needed for cellular growth and reproduction (Averill & Eldredge,…

insoluble organic compound usually located in biological organisms or systems. A variety of test for different substances would be done in this experiment. The Molisch test is not carbohydrate specific but all monosaccharides disaccharides and polysaccharides barring exceptions should give a positive test for it (Harpercollege.edu 2015) . These give a positive test because hydrochloric acid dehydrates the carbohydrate to give an aldehyde . This aldehyde then condenses with phenol molecules in…

that is made up of 3 beta sheets and an alpha helix. Many have been studying the effects that chlorotoxin has on cancer cells. Some of the ingredients that make up the scorpion venom are histamine, serotonin, histamine releasing factors, bio-polysaccharides and protease inhibitors. This composition of the venom has bound to the excitable cell membranes by choosing where to bind. The many ways that they have achieved this is by either changing chlorotoxin or deriving…

In everyday life, people use disinfectants, substances used to destroy viruses and microbes such as bacteria and fungi1, to clean their bathrooms. If not properly sterilized and cleaned, the bathroom can be a domain for numerous bacteria including ubiquitous Serratia Marcescens, a short, rod shaped, facultative anaerobic, opportunistic pathogen that can cause nosocomial infections such as urinary tract infections, bacteraemia, meningitis, sepsis and cerebral abscesses2. Facultative anaerobic…

Introduction Starch, a complex polysaccharide comprised of glucose monomers, is used as a storage compound in the plants it is found to be present in. As a result it is a renewable and biodegradable source of food for humans and many animals that devour these plants (Man et al. 2013). In 1831 a discovery was made by Erhard Leuchs that when mixed with human saliva, starch molecules are broken down into simpler compounds. (Butterworth, Ellis, Warren 2011). These polysaccharides made of glucose…

and also carry out respiration, photosynthetic membrane posses pigments and spread throughout the cell, nitrogen-fixing membrane is present in the cell membrane for fixing nitrogen. The capsule/glycocalyx is a stiff structure which is made of polysaccharides and…
