These principle substances include carbohydrates, proteins, fats, minerals and vitamins. We can test for the presence of these important compounds in food by using chemical reagents that react in predictable ways in the presence of these nutrients.

...Biologically Important Molecules, Carbohydrates, Proteins, lipids and Nucleic Acids Tiffany Osbey Jackson State University Lab Report Authors: Tiffany Osbey Portia Mcmlertrey Jamia Ransome Darrius Bryant Abstract: Organic molecules are those primarily made up of carbon, hydrogen and oxygen. The common organic compounds of living organisms are carbohydrates, proteins, lipids, and nucleic acids. Each of these macromolecules (polymers) are made of smaller subunits (monomers). The bonds between these subunits are formed by dehydration synthesis. This process requires energy; a molecule of water is removed (dehydration) and a covalent bond is formed between the subunits (Fig.1). Breaking this bond is called hydrolysis; it requires the addition of a water molecule and releases energy. Each class of these macromolecules has different structures and properties. For example, lipids (composed of fatty acids) have many C-H bonds and relatively little oxygen, while proteins (composed of amino acids) have amino groups (-NH3+) and carboxyl (-COOH) groups. These characteristic subunits and chemical groups impart different properties to the macromolecules. For example, monosaccharide’s such as glucose are polar and soluble in water, whereas lipids are non-polar and insoluble in water. Objective: Perform lest to detect the presence of biology important carbohydrates, proteins lipids and nucleic acid. Explain the importance of a positive and a negative control in biochemical test. Use biochemical...

...UTAR FHSC1214 Fundamentals of Cell Biology Trimester 1 How YOU can do well in BIOLOGY Follow the 4A’s and you can expect A’s. A ttitude • Attend ALL lectures, tutorials and practicals on time without fail. • Be attentive in class and revise your notes after class while the topic is still fresh in your mind. Why waste time re-reading 2-3 months later? • Do your assignments faithfully as they carry marks for the finals. • Come prepared for lessons (i.e. read up beforehand). • Read up beforehand before attending lectures so that you won’t be lost and wasted hours of your life week after week. • Why stress yourself out if you can avoid it? Do NOT count on last minute revision for tests and examinations, as it will be too late to catch up and seek help in areas where you may find confusing or unclear of. • Why panic before exams because you can’t find this or that? Keep separate files for lecture, tutorial and practical. File up the respective notes systematically so that you do not lose them along the semester. • Do you expect the lecturer/ tutor to be available all the time to answer your questions? It is YOUR responsibility to take the initiative to clear your doubts or satisfy your curiosity to understand certain scientific phenomena by reading up on the relevant topics. A Based on a true story… A professor at the National University of Singapore recounts how on one occasion a student consulted him days before the exam. Student:...

...Dear nutrition student, Thank you for inquiring about my RD/DTR study guide. And yes, there is no catch, the study guide is COMPLETELY FREE! All I ask for is some feedback. So feel free to shoot me any questions/comments! A little background: This study guide is the culmination of years of my own research. And after careful thought, I put into the study guide what I feel are the most important concepts you need to know for the RD/DTR exam. If you notice, I spent much time teaching you in detail the concepts you need to know, not just “spitting” you questions with little or no explanation. I believe this is important. I know you might be thinking “oh, how am I going to absorb and learn all this material?” I say, just read and answer the questions at your own pace. Simply test yourself and of course take some breaks along the way. Just take it one concept at a time. After you have mastered one concept, then move on to the next. I know if you study whole-heartedly what I have outlined in this study guide, you are sure to pass! GOOD LUCK!

The steps of nursing process 1)Assesment 2)Diagnosis 3)Planning 4)Implementation 5)Evaluation Assessment An RN uses a systematic, dynamic way to collect and analyze data about a client, the first step in delivering nursing care. Assessment includes not only physiological data, but also psychological, sociocultural, spiritual, economic, and life-style factors as well. For example, a nurse’s assessment of a hospitalized patient in pain includes not only the physical causes and manifestations of pain, but the patient’s response—an inability to get out of bed, refusal to eat, withdrawal from family members, anger directed at hospital staff, fear, or request for more pain mediation. Diagnosis The nursing diagnosis is the nurse’s clinical judgment about the client’s response to actual or potential health conditions or needs. The diagnosis reflects not only that the patient is in pain, but that the pain has caused other problems such as anxiety, poor nutrition, and conflict within the family, or has the potential to cause complications—for example, respiratory infection is a potential hazard...

...INTRODUCTION Mung bean (Vigna radiata L. Wilczek) sprouts can be considered one of the most common vegetables consumed in the Philippines due to availability and nutritional value (Del Rosario, 2003 and FNRI, 1997). One cup of raw mung bean sprouts contains 48 calories, 6.5 grams of protein, 1.5 grams of fat, and 5.6 grams of carbohydrate. One cup of cooked bean sprouts contains 48 calories, 6.6 grams of protein, 1.8 grams of fat, and 4.6 grams of carbohydrate. In addition, sprouts are a good source of minerals and vitamins, particularly vitamins B1, B2, and C (http://ianrpubs.unl.edu/horticulture). Mung bean sprouts are low in calories and exceptionally high in potassium. A nutritious sprouted mung bean offers the same amount of vitamin A as a lemon, the niacin of a banana, the thiamine of an avocado, the riboflavin of a dried apple, the carbohydrate content of a melon and the ascorbic acid of a loganberry (http://www.specialtyproduce.com). The sprouting process encourages the rapid growth of microorganisms that reach very high numbers in the finished product (Fu et al., 2000). Seed sprouting provides an excellent environment for the growth of many types of organisms. The release of nutrients from the sprouting seeds, the moisture resulting from the irrigation process, the aerobic conditions, pH and temperatures favorable to mesophiles all contribute to the rapid expansion of microbial population, including food pathogens, during sprouting. Population as high as...
