Did you know that placenta abruption occurs in 1 in 100 pregnancies? The placenta is the way the baby receives food and oxygen through the umbilical cord which attaches to the wall of the uterus. In the Maternal Early Pregnancy Serum Metabolomics Profile and Abnormal Vaginal Bleeding as Predictors of Placenta Abruption: A Prospective Study, by Blzu Gelya he reported that women ages 20-34 had placenta abruption 64% out of others aged mothers. Also he reported Non-Hispanic whites had higher chance…

Introduction The purpose of this lab was to identify the lipids in an egg yolk and to identify the amount of lipids in milk [1]. To extract the lipids from the egg yolk, the egg yolk needed to be combined with an organic solvent such as a mixture of CHCl3/MeOH. An organic solvent was needed to carry the extracted lipids up the TLC plate because the plate was polar, due to the presence of silica gel (silanol groups). To compare relatively similar lipids to the ones found in the egg yolk, the egg…

blood vessels to prevent excessive blood loss. If the protein is missing or its function disrupted by a mutation, it cannot participate in this clotting process. Factor VIII is a cofactor for factor IX that, in the presence of calcium ions and phospholipids, forms a complex that activates factor X, which is an enzyme that also helps clot blood by converting fibrinogen to fibrin. Factor VIII is produced in liver cells and endothelial…

Diet Analysis Throughout the week of September twenty ninth through October fifth I created a food log to help me further analyze my diet. I noticed that my diet is lacking dietary fiber, potassium, iron, magnesium, vitamin A, D, and choline. I was able to know this by logging my food every time I ate on a website called SuperTracker where it can tell you the food sources you’re missing along with your activity levels. Dietary Fibers primary role in the body is to strengthen the walls and to…

complex carbs contain fibers which cannot be digested. This helps controlling the blood glucose levels by slowing the rate of absorbing sugar. Lipids are another type of macromolecules. They also are a source of energy and divide into steroids, phospholipids and fatty acids. The unsaturated fats increase…

Structure and Functional Differences and Similarities of Prokaryotes and Eukaryotes All living organisms are made up of cells. Different types of organisms require different cellular structures to function properly. Eukaryotes are structurally more complex than prokaryotes. While prokaryotes don’t have any membrane-bound organelles in common with eukaryotes, prokaryotes do have some non-membrane-bound components in common with eukaryotes. Eukaryotes are made of several key organelles whose…

that can be exported (Paterson and Fodor, 2012). M proteins also plays crucial role when the new virus buds off. It blocks the nuclear pores to stop re-entry of the newly formed RNAs and allows assembly of the new virus. M proteins can bind the phospholipid tail of the cell membrane with the viral envelope of the glycoproteins around the encapsidated RNA and bud off the host cell (Figure 1) (Gomez-Puertas et al, 2000, Cao et al,…

Despite modern knowledge, technology, and science, doctors still prescribe drugs identical to cocaine, alcohol, cigarettes, caffeine, and heroine (Khosh and Beneda). The medication ritalin is a stimulant that works the same way those harmful drugs do. In 1993, 2,500,000 prescriptions were written for ritalin (Khosh and Beneda). As is commonly known, all prescription drugs have side effects, but imagine the side effects of drugs identical to heroin and cocaine. Ritalin is a stimulant…

serves as a support to the cell and helps maintain its shape. The cell is made up of a mix of protein and lipid. The lipid helps to give membranes their flexibility and the protein which helps in the transfer of molecules across the membrane. Phospholipids are the main molecules of the cell membrane. It forms a bilayer in which their hydrophilic (attracted to water) head areas are arranged to face the cytosol (liquid part of the cell) and hydrophobic (repel water) tail areas face outside the…
