Summary Introduction

To explain: The digestion and absorption of three biomolecules including location, enzymes, and the mechanisms in tabular form.

Introduction: Digestion is a process by which the body fulfills its demand for energy to operate. The conversion of large insoluble molecules into smaller molecules is called digestion. Digestion typically consists of two parts. In one part, the large food chunks are broken down into smaller ones. In the second part, the smaller food particles are digested to the molecular level by the enzymes in chemical digestion Digestion process makes the biomolecules ready for absorption. The movement of digested particles from the lumen of the intestine to the extracellular fluid is called absorption.

Summary Introduction

To explain: The process of iron absorption.

Introduction: The absorption of minerals usually takes place through active transport. The intestinal absorption of the iron is regulated. The decrease of body concentration of iron gives rise to enhance uptake of the iron at intestine.

1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple different routes of administration provides greater insight than just a single route of administration alone. The following data was collected in 250 g rats following bolus iv, oral (po), and intraperitoneal (ip) administration.Using this data and set of graphs, determine: (a) k, C0, V, and AUC* for the bolus iv data  (b) k, ka, B1, and AUC* for the po data  (c) k, ka, B1, and AUC* for the ip data  (d) relative bioavailability for po vs ip, Fpo/Fip  (e) absolute po bioavailability, (f)Fpo absolute ip bioavailability, Fip    MAKE SURE ANSWERS HAVE UNITS if appropriate. SHOW ALL WORK, including equation used, variables used and each step to your solution.
2. Drug quantification from plasma is commonly performed by using techniques such as HPLC or LC/MS. However, these methods do have limitations, and investigators may choose to use a radiolabeled analog of a drug instead. Radioligands are molecules that contain radioactive isotopes, commonly 3H or 14C. This technique allows investigators to quantify drug concentration from radiation measurements. The following measurements were made in 250 g rats following oral administration of 18.2 µCi of a 14C-labeled drug of interest: Time (min) Plasma Radiation Levels (µCi/L) 0 0.0 2 9.7 4 19.2 7 25.3 9 37.8 12 39.6 14 45.8 17 48.8 20 52.0 25 56.4 30 59.2 35 60.1 40 61.1 45 62.1 50 62.8 60 63.1 70 62.1 80 60.1 90 57.3 100 55.5 110 53.7 120 52.2 150 48.0 180 45.0 240 39.0  Note that a µCi is a measure of the amount of radioactivity and hence is a measure of the amount of drug present.  Given that the oral bioavailability of this drug is known to be essentially 100%, estimate the following from this…
The current nutrition labelling regulation in Hong Kong requires food manufacturer to list E+7 information on the package of pre-packaged food products. Do you think that more nutrients, such as calcium and cholesterol, shall be included?
