The Roles Of Carbohydrates And Their Cooperation Within The Immune System

They are all polymers made during dehydration synthesis reactions from monomers. These reactions result in the loss of water forming strong covalent bonds. They are referred to as endergonic reactions since they require an input of energy. Hydrolytic reactions are the opposite as they break polymers into single unit monomers using water and in the process releasing energy thus referred to as exergonic reactions (Gorrod, 1985). The monomer form of carbohydrates is a monosaccharide e.g. glucose (used for energy in cells), fructose and ribose. When two monosaccharides undergo a dehydration synthesis reaction they form a disaccharide e.g. sucrose, which is a combination of glucose and fructose. Sucrose is used for transport in plants. Polysaccharides consist of three or more covalently bonded monosaccharides. Starch and glycogen are good examples and are both used in energy storage in plants and animals respectively. Monomers of lipids are fatty acids and glycerol while amino acids are monomers of proteins. Amino acids mainly function to regulate different cell functions as well as catalyze various cell reactions. Nucleotides are the monomers of nucleic acids and they function in storing the genetic information of a cell (DNA) and synthesis of proteins (RNA). All these monomers undergo dehydration synthesis reactions to form their corresponding polymers and are used in

Then, nucleic acids are made up of nucleotides and has the ability to make new cells. Finally, Lipids. Lipids are made up of glycerol and fatty acids. Lipids play a big role in the body, it provides cushion and insulation for the larger organisms in our bodies. All of these macromolecules and monomers are needed to make energy.

A polysaccharide is when a numerous amounts of monosaccharides are joined together forming a molecule. Both glycogen and starch are polysaccharides. Glycogen is a energy storage carbohydrate found in animals. Glycogen in comparison to starch is much more highly branched. Starch is a polysaccharide that functions as a energy carbohydrate store in plants. This can be found mostly in potatoes and cereals. It is formed by the bonding together of many of glucose subunits into long chains. The actions of hydrolysis is the chemical breakdown of a compound due to the reaction of water. In order for hydrolysis to occur water must be added to the compound

What is metabolism? How are carbohydrates, lipids, and proteins metabolized? What role does enzymes play in metabolisms?Metabolism is the chemical process that occur within a living organism in order to maintain life.Carbohydrate metabolism- begins with digestion in the small intestine where monosaccharides are absorbed into the blood stream. Blood sugar concentrations are controlled by three hormones: insulin, glucagon, and epinephrine. If the concentration of glucose in the blood is too high, insulin is secreted by the pancreas.Lipid metabolism- are involved with Fatty Acid Oxidation to produce energy or the synthesis of lipids which is called Lipogenesis. Lipid metabolism is closely connected to the

First of all, let’s discuss the carbohydrate molecule, which contains carbon, oxygen, and hydrogen atoms. Carbohydrates are the most important source of energy for our body and our digestive system changes carbohydrates into glucose (sugar). Carbohydrates contain monosaccharides (one simple sugar), disaccharides (two simple sugars), and polysaccharides (many simple sugars). These simple sugars are joined by glycosidic bonds to form

High carb diets are utilized to glycogen stored in the liver and muscles. Glycogen is a

Biomolecules are essential to the cell processes of human life. These molecules are broken down into three major components: Saccharides, Lipids, and Peptides, each carrying specific functions for the processes of the body. Saccharides, our focal point in this lab, enhance the synthesis of other biomolecules by supplying them with carbon, form structure in cells and tissues, provide fuel for metabolism, and are responsible for the storage of glucose. Saccharides are further broken down into three biomolecules: Monosaccharides, Disaccharides, and Polysaccharides. Monosaccharides are simple sugars that can be classified as Aldehyde or Ketone. These Monosaccharides can be easily identified with the reaction between the Benedict’s Reagent with

Mutations in the NAGA gene interfere with the ability of the alpha-N-acetylgalactosaminidase enzyme to perform its role in breaking down glycoproteins and glycolipids. These substances accumulate

The purpose of this lab was to test 12 different aqueous solutions containing macromolecules, 11 of which were controls while the final one was an unknown. Three different test were carried on each of the 12 samples. The first was an iodine test for the presents of either starch and glycogen in the sample. Iodine is a clear colourless liquid before being added to any of the solutions. The way starch is identified is by the solution turning blue-black.The solution does this because of the amylose in the starch, amylose and amylopectin are the two parts that make up a starch, amylose is made up of 200 to 5,000 alpha -D-glucose, which coil into a tight spring structure(Toole, 2004). When the iodine is added it is pushed by the starch into the middle of this coil this creates a tight helix and this turns the solution black/ dark blue.(Ophardt, 2003) The way Glycogen is identified is when the solution turns reddish-brown. Glycogen is very similar to amylopectin as it is made up of alpha glucose units joined at 1-4 and 1-6 and it is a branched structure. (Toole, 2004) Iodine affects glycogen similarly as it does amylose.

Cancer glutamine metabolism has been a whole lot complicated to figure it out since there is flexibility of the metabolic systems as well as the number of free nutrients to which the cells have access to simultaneously. The cancer cells in culture are avid consumers of glutamine and metabolize glutamine at higher rates compared to other amino acids. Glucose on the other hand is said to play a crucial role in cancer cell metabolism and glutamine is second and both are needed for proliferating cancer cells for bioenergetics and synthesis of intermediates for macromolecular. The Warbug’s effect states that most cancer cells rely aerobic glycolysis to generate energy for cellular processes which yields less adenosine 5’-triphosphate (ATP). In

Abstract: Selectins are carbohydrate-binding proteins that play a vital role in inflammatory responses. These proteins are involved in the homing of leukocytes and have been implicated in numerous diseases, including autoimmune diseases such as multiple sclerosis as well as various form of cancer. In addressing the role of selectins in autoimmune diseases, it has been found that they involved in the trafficking of immune cells to secondary lymphoid organs under normal conditions as well as to peripheral tissues during inflammation. Precise selectin–ligand interactions facilitate the recruitment of distinct immune cell subpopulations in specific target organs during autoimmune diseases. Additionally, selectins (and their ligands) are also vital for homeostasis and immune cell activation. Tissue-specific, selectin antagonists are fairly promising new therapeutic approaches for the treatment of autoimmune and inflammatory diseases, however, a more precise mechanism for selectin leukocyte targeting must be uncovered first. Selectins also have been found to translate their roles in cellular adhesion to metastatic progression when the correct ligand is present. Though selectins have been identified as potential facilitators of metastasis, they have not been studied as drug targets for treating cancer progression and metastasis. However, targeting selectins as a cancer metastasis treatment could prove very successful as seen from initial positive clinical findings regarding heparin

There are four types of biomolecules, carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are large chains of sugar found in food and living tissues. This includes sugars, starch, and cellulose. They have the same ratio of hydrogen and oxygen that water has, 2:1. They are broken down to release energy in the animal body. Lipids are any organic compounds that are fatty acids and don’t dissolve in water but do in organic solvents. Fatty acids can be found in natural oils, waxes, and steroids. Proteins are macromolecules that do everything in the cell. They are tools and machines that make things happen. Nucleic acids are long strands of nucleotides, and function primarily in storage and transmission of genetic information. There are two types of nucleic acids, DNA and RNA. DNA is the genetic material of all cellular organisms, and RNA sends out messages from the information that is held in the DNA.

Emerging studies highlight the relationship between proteome and immune cell activation and explore the interaction between metabolic activities and immune responses. Recent investigation of how specific ligands affect immune cell proteome and function underlies that different agents may cause diverse proteome alterations in immune cells such as DCs (Pearce and Everts, 2015). Apparently, proteome changes including metabolic state affect DC function. Recent technical developments together with the increasing availability of high-throughput methodologies have enabled a more comprehensive overview of these proteome alterations and thus provide new approaches to find better agents for DC maturation. Importantly, immune cell activation is also

The term ‘’Carbohydrates’’ is defined as the carbon compounds which contains hydroxyl groups in large quantities (King, 2013). Carbohydrates are those organic compounds which have the empirical formula CnH2nOn, or (CH2O)n (Fromm 1997). Carbohydrates are one of the four types of organic compounds in living cells that are produces during photosynthesis and are the important source of energy in both plants and animals (Ahmed 2014). They are built from monosaccharides. These monosacchradies are the small molecules that consists of three to nine carbon atoms and differ in size and in the stereochemical configuration at one or more carbon centers. The simplest carbohydrates also contain either an aldehyde or ketone compounds (freeman 2002). Carbohydrates are classified as simple and complex carbohydrates. The classification of carbohtdydrates is based on the chemical structure of the food and how fast it absorbs. Simple carbohydrates contains single or double sugars in their chemical structure whereas complex carbohydrates consists of three or more sugars (ahmed 2014). There are four major types of carbohydrates depending on their chemical composition.
