Polysaccharide

According to archaeological evidence, dental caries went from rare to common when our ancestors began to farm.1 This fact will be important as we begin to study the characteristics of Streptococcus mutans that enables them to be the main initiators of dental caries in human subjects. The human mouth contains hundreds of species of bacteria, some improve oral health while some do not. Streptococcus mutans is one of the worst of these bacteria. “Streptococcus mutans [does] have a prominent,…

a means for energy and cell support in plants. .( Parsi et al, 2016) They can be further categorized by the subtitles monosaccharides, disaccharides, and polysaccharides. Since monosaccharides are monomers and thus simple sugars, as monomers are added to the chain they become polysaccharides. In addition starches and glycogens are polysaccharides. .( Parsi et al, 2016) Proteins in comparison are composed of carbon, hydrogen, oxygen, nitrogen, and occasionally sulfur. Polymers of amino acids…

protect cells from engulfment by eukaryotic cells, such as macrophages. In other words, when S strain covers itself with a polysaccharide capsule, it protects it from the host’s immune system, resulting in the death of the host. In addition to that, R strain which is genetically identical, differ from S strain because it carries mutation that prevents it from making polysaccharide coat. According to the definition of mutation in iGenetics Third Edition page 10 under the topic of Griffith…

Macromolecules are in a clearing technique of life,which make up living beings. It is an expansive particle that is joined by littler atoms by shaping new bonds. Illustrations of Macromolecules would be nucleic acids, proteins, and polysaccharides (2 or more sugars). These segments are starches, lipids, proteins, and nucleic acids. Starches consisit completely of glucose monomers and are joined by glycosidic linkages, just found in plants. Lipids are a vast gathering of natural particles that…

would be nucleic acids, proteins, and polysaccharides (2 or more sugars). The biological components are composed of starches, proteins, lipids, and nucleic acids. Starches consisit entirely of glucose monomers and are joined by glycosidic linkages, only found in plants. Lipids are a large group of biological molecules that…

The subject that is being read is Prokaryotes. An example of a prokaryote is bacteria. Bacteria traits are usually for a genus and are extremely important to the cell. Bacteria come within various shapes, such as spirals, cocci, rods, etc. These shapes are very useful for the prokaryotes. Prokaryotes do not have a developed nucleus instead the cell has a nucleoid which is also known as a nuclear bound and it lacks the cytoplasm membrane. Prokaryote structures consist of the flagella, pili, and…

Monosaccharides are the unmistakable sugars. Two monosaccharides make a disaccharide. Three or more monosaccharides are a polysaccharide. Glucose, fructose, and galactose are monosaccharides. Sucrose, lactose, and maltose are disaccharides. Starch and glycogen are polysaccharides. Central sugars can be found by utilizing Benedict's test. Proteins are made of carbon, hydrogen, oxygen, nitrogen, and now and again sulfur. Proteins are covalently supported…

same polysaccharide-rich diet were fed. It had been noted in another study by turnbaugh et.al that the development of obesity had been associated with an increase of Firmicutes and decrease of Bacteroidetes when both ob/ob mice and conventional mice were fed a typical western diet as compared to another group of mice consuming a high polysaccharide and low fat diet. It was observed in the obese mice that coding for enzymes that assist the extraction of energy from indigestible polysaccharides…

Attachment Uses the TCP acquired from V. Cholerae to attach to intestinal mucosal cells. Invasion Forms a biofilm along the intestinal wall, clearing nearby cilia and producing antibiotics that will kill nearby competing bacteria. Evasion The polysaccharide capsule obtained from B. Anthracis prevents engulfment by macrophages as well as preventing opsonization of the bacterium. Toxin…

Chitosan is a natural linear amino polysaccharide gained from chitin which is, after cellulose, the second more common biopolymer on earth. Chitin is the primary component in the shells of crustaceans such as shrimp, crab, and lobster. Chitin is present in crayfish, insects, and vegetal species mainly in the walls of fungi. These species require nitrogen for nutritional cycle. Chitin has been sourced from different originate and its composition shown in table 2.1 (synowie). Small quantity of…
