Phospholipid

According to the cell theory, the cell is the smallest form of life but there are many parts of a cell which allow the cell to do the job it is assigned correctly. An example of a cell would be the animal cell, which is a eukaryotic cell or a cell that contains a plasma membrane. Inside the membrane there are parts of the cell called the organelles. (Animal Cell Structure, 2005) Organelles inside the cell have specific jobs to perform for the cell, organelles include the ribosomes, vacuoles,…

When explaining new material to students, educators frequently employ metaphor during their lectures to make new, difficult material simpler and more accessible to the student than it otherwise would be. This teaching technique is logical: metaphors provide the link between immaterial, complex target domains of knowledge and readily understandable source domains that the students have been exposed to in their everyday lives, in order to make the new information comprehensible to the learner. In…

This results in the activation of the Gq/11 which stimulates the inositol phospholipid signalling pathways, resulting in the production of IP3 and DAG. This causes the downstream increase of intracellular calcium and activation phospholipase D and A2. The overall physiological effect is vasoconstriction, bronchoconstriction, increase…

Lipids: Lipids have a hydrophobic nature because of the predominantly of hydrocarbon chains in their structure. They are insoluble or poorly soluble in water, but readily soluble in non polar solvents such as ether and benzene. Characteristics of Lipids:  Amphiphatic  Naturally occurring  Soluble in organic solvents but insoluble in water  Undergo saponification  Undergo emulsification Classification and biological functions of Lipids: • Fatty Acids:  Energy sources  Biosynthetic…

Case Study 1 Vivek Poudel University of Texas at Arlington In partial fulfillment of the requirements of N5315 Advanced Pathophysiology Mary Schira Ph.D., RN, ACNP-BC September 19, 2017 What causes systemic lupus erythematosus (lupus)? Why did the NP suspect that Sharon may have lupus? (15 pts) Exact cause of systemic lupus erythematosus (lupus) is not known. It is believed that some people are born with tendency to develop lupus that is triggered by a viral infection, chemical…

not penetrate the memory. This would cause the bacteria to be dysfunctional. When observing gram-positive bacteria one can perceive that the bacteria consist of teichoic acid, surface protein, lipoteichoic acid, peptide-glycan, cell membrane, and phospholipid. When observing the gram-negative bacteria one can note that this bacteria consist of lipopolysaccharide, surface protein, outer membrane, lipoprotein, peptide glycan, and cell membrane. These two are mainly composed of a lot of different…

the exchange of ions and solutes, protect the cell, cell communication and adhesion, and some signaling mechanisms (Mandraccia 2014). Most eukaryotic cellular membrane are made up of phospholipid bilayer, a phospholipid molecule with fatty acids, which has proteins embedded within. The proteins within the phospholipid bilayer are not fixed within its position and its functions is to regulate the passage of molecules and an identification tag (Gupta, 2009). Within “Cellular Membranes: Effects of…

linked hydrocarbon rings forming the bulky steroid structure. There is a hydrocarbon tail linked to one end of the steroid and a hydroxyl group linked to the other end. The hydroxyl group is able to form hydrogen bonds with nearby carbonyl oxygen of phospholipid and sphingolipid headgroups.Cholesterol is referred as an amphipathic molecule, that it contains its hydrophilic and hydrophobic parts. Cholesterol is usually synthesized in animals and smaller cholesterol can be generated in plants.…

BIOMOLECULES It is from the foods we eat that we get the essential compounds that our body needs. These types of compounds are used by our body for energy and growth. In this chapter, you will learn about biomolecules and their functions in the human body. iEngage Nutrition Facts Objectives To examine nutrition facts from food labels To recognize the importance of knowing the food labels Materials food label paper pen Procedures 1. Examine carefully the nutrition facts of…

We, the organelles of Cell city need to unite and function as one. This can be achieved through the sole leadership of us, the Smooth-ER. We are like a tube that winds and bends. Our insides are surrounded by a phospholipid membrane, the same one used around this city. It might be easy to confuse us with our opponent, the Rough-ER, but make no mistake the Rough-ER are flat like pancakes while we are totally tubular. Although we create adrenal steroids, we also play a large role in the…
