Cholesterol Lab Report

Heart Healthy Fat In this experiment the amount of fat will be seen in four different types margarine. Margarine is mostly made of water and fat. There are two different types of fat, saturated and unsaturated.

The purpose of this experiment was to test which form of cream would produce the most amount of fat.

The first step that needed to be done in this experiment was adding hydrochloric acid (HCl)

As detailed in Pavia 's Organic Laboratory techniques the reaction is expected to proceed via the following reaction:

Cholesterol is a waxy, fat like product found in cells throughout your body. It helps in building hormones like estrogen, progesterone, testosterone, and in the production of cortisol, the stress hormone. Cholesterol also helps the body in the absorption of vitamins A, D, K, and E. Although your body produces some cholesterol, it is found in many of the foods you eat.

There were no changes made in the procedure. Procedure from the lab manual was followed.

On a thin chromatography plate, five spots were placed ( as shown in table 2) and the plate was developed using chloroform/methanol. This was later visualized with dragendorff’s reagent under the UV light. All separated components were observed, identified and recorded.

Results: There were different food dyes, solutions, beakers, chromatography strips, Erlenmeyer flasks, tooth picks, and watch glasses on the lab tables. There was also a ruler and a pencil. The first thing I did was prepare two strips of chromatography paper as instructed in the procedures. Next I used a toothpick

You should start on your life's work in regards to cholesterol testing at about the age of 20; while it is likely that your levels should be normal at that time of your life, it would provide a baseline for your doctor. A test can follow every five years until symptoms of high cholesterol become evident when cholesterol testing would become more frequent. The lipoprotein profile shows levels for good and bad cholesterol.

A cholesterol granuloma is a rare condition that results from a foreign body response to the presence of crystallized cholesterol (1). It is more commonly seen in males and usually occurs in middle aged men (4). The most typical locations are middle ear, petrous apex, and mastoid (2). Although uncommon, orbital involvement usually occurs in the lateral portion of the superior orbital ridge (3). The most common presenting symptom reported is proptosis (5). Ptosis and periorbital pain have also been reported. Restriction in ocular movements may be seen due to compression of the globe and extrinsic ocular muscles. Although uncommon, reduced visual acuity has been reported in relation to induced astigmatism or choroid folds involving the macula (5). Surgical excision has a high success rate with a low incidence of recurrence. We present a rare presentation of an orbital cholesterol granuloma causing vision loss that was successfully removed by surgical excision.

Learn how to prevent high cholesterol and know what your cholesterol levels actually mean. A good time to get your blood cholesterol checked and take steps to lower it if your levels are elevated is in September because it is National Cholesterol Education Month. National Cholesterol Education Month is also a good time to learn about lipid profiles and about food and lifestyle choices that help you reach personal cholesterol goals. The National Cholesterol Education Program (NCEP) states that adults aged 20 years or older have their cholesterol checked every four to six years to stay on track with their cholesterol levels. To our surprise, many people do not know that their cholesterol levels are high given that having high cholesterol generally doesn’t have any symptoms. However, doctors can administer a simple blood test called a lipoprotein profile to check your cholesterol levels. A lipoprotein profile can measure your total cholesterol levels, including LDL (low-density lipoprotein, or "bad" cholesterol), HDL (high-density lipoprotein, or "good" cholesterol), and triglycerides (NECP). According to the Centers for Disease Control and Prevention (2013), “high cholesterol is a major risk factor for heart disease which is currently the leading cause of death in the United States.” Preventive recommendations for cholesterol screening among young adults vary, but most experts agree on the need to screen young adults who have other risk factors for heart disease or stroke

Weyermann et al. (2010) observed the variability in the amounts of squalene and cholesterol found between and within donors. While cholesterol and squalene was found in all the latent fingerprints of their six donors, there was a high variability in the initial quantity of these materials, both between and within these donors. With respect to the ageing kinetics as a function of time, they conducted an experiment on two different surfaces (i.e. porous for 30 days and non-porous for 65 hours). It was found that squalene decreases at a faster rate on a non-porous surface (not detectable after one week) than on a porous surface (still detectable after 30 days).

In this paper, we proposed a novel non-invasive cholesterol level measurement model, to measure the total cholesterol (TC) and LDL levels of the human body. The proposed method predicts the cholesterol levels of human subjects using the lipid deposition existing in the cornea region of their eye. For this study, a database was created using the eye images collected from the subjects with normal/ abnormal cholesterol levels and their serum cholesterol levels. After data collection, the eye images in the database were pre-processed for specular reflection removal and the corneal lipid deposition was segmented from the other regions of the eye image. The statistical features were extracted from the segmented corneal lipid deposition.

Carbohydrates are the product that made up from carbon, hydrogen and oxygen. Carbohydrates are form by the combination of carbon dioxide and water molecules. The carbohydrates contain two specific functional group in it which is the hydroxyl groups and carbonyl groups.A reducing sugar is a type of sugar with is an aldehyde group.This means that sugar can act as a reducing agent.The procces of reducing sugar is isomerisation,example of reducing sugar islactose,maltose,glucose and fructose.All monosaccharides are capable of reducing other chemicals such as copper (II) sulphate to copper oxide.Beside that disaccharides such as maltose and lactose are reducing sugar,however sucrose is non reducing

pressure varies person to person depending on a variety of personal factors. Blood pressure is an
