Phospholipid

Taking care of your body is a necessity that requires a daily basis commitment. Dieting is known as the “only way” to become healthy, but simply eating wiser food choices that still satisfy your stomach is certainly an option. Read carefully Mitchell, as I am going to inform and caution you to become aware of the composition of the food that you are consuming and how it affects your body. After reading my helpful tips, you will be more acquainted with the different carbon compounds and how they…

The structure and function of carbohydrates (25 Marks) Carbohydrates are made from Carbon (C), Hydrogen (H) and Oxygen (O). A monosaccharide is the monomer sub unit of carbohydrates and can be joined together through a condensation reaction to form a glycosidic bond between the two monomers which is known as a disaccharide. The above diagram shows a condensation reaction taking place. There is a reaction between two monomer sub units, in this case α-glucose and ethanol, which involves the…

are responsible for many functions such as providing diffusion pathway from skin surface to SC. The lipophilic matrix (Figure 1.) is unique because of its content as it composes of ceramides, free fatty acids and cholesterol but are absent of phospholipids which is surprising as…

Introduction Influenza A virus is a respiratory pathogen that seasonally causes approximately 200,000 hospitalizations every year in US alone and affects human health worldwide extensively [1]. Seasonal viruses circulating in the human population cause annual epidemics with about 500,000 deaths per year. Furthermore, novel strains of influenza A virus without pre-existing immunity could cause a global pandemic with a high fatality rate; the 2009 H1N1 pandemic caused 151,700–575,400 deaths in…

Level 3 Applied Science Unit 11 physiology of Human Body Systems Task 1: ORGANELLE DIAGRAM FORM FUNCTION Nucleolus • The nucleolus is a darker staining region of the nucleus. It is non-membrane bound structure composed of ribonucleic acids (RNA) and proteins. It makes ribosomes inside the nucleus and contains all the DNA of the cell. It is also used for cellular reproduction and it is often referred to as the brain of the cell as it controls what goes on. Golgi…

Aging Context Aging is treated as a vital factor in the etiology of human disease (ES-2014-aging). It is also an important risk factor for AD and PD onset and progression. Biologically, aging is an inevitable biological process that is characterized by a progressive decline in physiological function, including cognition, and by the increased susceptibility to disease (RX-2013). Oxidative stress and mitochondrial malfunction are two interdependent mechanisms that play a central role in brain…

The CCR5-Δ32 Allele: A Natural Resistance to HIV Virus Human immunodeficiency virus, most commonly known as HIV, is an acquired virus that attacks the immune system of the host and eventually leads to acquired immunodeficiency syndrome otherwise known as AIDS. HIV is a relatively new disease in human populations, AIDS was first observed in homosexual males in 1981 (Herron et al., 2014, p. 2). Later, in 1983, soon after the discovery of AIDS, scientists identified HIV virus as being responsible…

bacterium is not known to be harmful to humans or other animals. Xanthomonas axonopodis is classified as a gram negative Protobacteria. Because the bacterium are gram negative, they all have an outer membrane of lipopolysaccharide (LPS) and a phospholipid inner membrane.They are aerobic and rod…

1. Describe 3 targets of antibiotics, why each target is unique to the particular bacteria, and under what circumstance the bacteria could be resistant to that particular drug. (5 pts) As the name implies 50s subunit protein synthesis inhibitors such as erythromycin inhibit protein synthesis by binding to the 50S subunit of the 23S rRNA molecule of the bacterial ribosome. This ultimately acts to block the exit of the growing peptide chain. It should be noted that gram+ bacteria more…

Xerox at headquarters, and with that our micro-V96 craft was propelled towards the cell membrane for the first leg of our journey to investigate the process of Protein Synthesis in a eukaryotic animal cell. The cell membrane is a delicate wall of phospholipid molecules, consisting of hydrophilic heads and hydrophobic tails that swayed and looked like a mosaic. Our craft could not enter the cell directly through the semi-permeable membrane as it consisted of a negatively charged polysaccharide…
