Case Study 1 The Structure of Insulin Focus concepts The three dimensional structure of insulin is examined and sequences of various animal insulins are compared. Prerequisites • • • Amino acid structure Protein architecture Basic immunology Background Diabetics lack the protein insulin‚ which is produced by the pancreatic β-cells of the islets of Langerhans. Insulin stimulates uptake of glucose from the blood into the tissues. Diabetes is treated by replacing the missing insulin. Human

Nursing Process: Assessment MSC: NCLEX: Physiological Integrity 2 2. A 76-year-old woman with a body mass index (BMI) of 17 kg/m and a low serum albumin level is being admitted by the nurse. Which assessment finding will the nurse expect to find? Restlessness Hypertension Pitting edema Food allergies a. b. c. d. ANS: C Edema occurs when serum albumin levels and plasma oncotic pressure decrease. The blood pressure and level of consciousness are not directly affected by malnutrition. Food allergies

3. Which MWCO dialysis membranes allowed both of these ions through? 50‚ 100‚ 200 4. Which materials diffused from the left beaker to the right beaker? Na+/Cl-‚ Urea‚ Glucose 5. Which did not? Why? Albumin did not diffuse from the left to the right beaker. The conclusion is that Albumin is a polar substance. Polar substances have a much lower solubility in the membrane phospholipids. Certain compounds that are intermediates of metabolism are not usually allowed through the membrane‚ as

is 60.07 . Do you think urea will diffuse through the 20 MWCO membrane? No‚ not at all ( Predict Ques. 1) 3/ Glucose is a six-carbon sugar. Albumin is a protein with 607 amino acids. The average molecular weight of a single amino acid is 135 g/mole. There is no reason to run these solutes at the 20 MWCO because : d. glucose and albumin are both too large to pass. 50 MWCO : Na+Cl- equilibrium at 10 min (9.00nM)

9/4/2014 Fillers within Protein Supplements Local gym enthusiasts are trying to reveal if certain new dietary supplements will actually help them gain muscle mass by providing high levels of protein. Before the users consume the new supplements they want to know if they are indeed true protein supplements or if the manufacturer used fillers as a mean to make more profit. “Do the new supplements contain fillers such as sugar and starch or are they pure protein?” This is important

INTRODUCTION: 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

Time: 2 hours BACKGROUND The principal chemical constituents of living matter are: water‚ mineral salts‚ organic compounds such as carbohydrates‚ proteins‚ lipids‚ nucleic acids. In this exercise we shall concentrate on carbohydrates‚ lipids‚ proteins‚ and we shall estimate the concentration of Vitamin C‚ an organic compound‚ in a solution‚ by the iodometric technique. • Carbohydrates include simple sugars‚ disaccharides and polysaccharides

Short answer questions – generally complex by their nature and require knowledge and integration of several different concepts 1. Explain what are the end goals of reproductive cloning and therapeutic cloning. Outline the steps both procedures share and the step(s) specific for each procedure. • Reproductive Cloning- Reproductive cloning is a type of cloning which is performed for the purpose of creating a duplicate copy of another organism. It is accomplished using a process called somatic cell
