derived from animals that contain a significant amount of carbohydrates. Carbohydrates are divided into two groups‚ simple carbohydrates and complex carbohydrates. Simple carbohydrates‚ sometimes called simple sugars‚ include fructose (fruit sugar)‚ sucrose (table sugar)‚ and lactose (milk sugar)‚ as well as several other sugars. Fruits are one of the richest natural sources of simple carbohydrates. Complex carbohydrates are also made up of sugars‚ but the sugar molecules are strung together to form

GUIDELINES FOR INTERNSHIP REPORT By Md. Shawan Udddin and M.A. Matin* INTRODUCTION 1.1 What Is Internship? Internship program is a pre-service training designed to render practical experience of a given job. In other words to employ achieved knowledge hand in hand is called internship. In a single word‚ “Standard method taken for searching knowledge or information is meant internship”. Internship is a process of acquiring practical knowledge about some theoretical lessons

In its modern forms‚ it is typically a sweet and enriched baked dessert. In its oldest forms‚ cakes were normally fried breads or cheesecakes‚ and normally had a disk shape. Determining whether a given food should be classified as bread‚ cake‚ or pastry can be difficult. Modern cake‚ especially layer cakes‚ normally contain a combination of flour

Reducing sugar can reduce Cu2+ into Cu+ and form a bricked-red precipitate (copper(I) oxide) which is insoluble in water. ii) Use of Benedict’s test Benedict’s test can show the presence of reducing sugar (all monosaccharide and disaccharide‚ except sucrose). Add Benedict’s solution into food samples (solution). Then mix them up and put into a water bath for 5 minutes. If reducing sugar is presence‚ there will be bricked-red precipitate. More is that‚ the variation of the color of the bricked-red

your body‚ the lack of reliable evidence to back up claims made by sport drink companies‚ the amount of money wasted and the concentration of the sport drinks available. Sports drinks have a negative effect on your health. The sugars fructose and sucrose are the main ingredients in most sport drinks; fructose is a monosaccharide which means the fructose cannot be broken down into simpler sugars by hydrolysis. Fructose can affect the kidney functions by evaluations in the uric acid; simulating fat

Plan a procedure that will allow you to compare quantitavely the glucose concentration in fresh samples of orange‚ lemon and grapefruit juice. Aim: The aim of this investigation is to produce a set of data which will enable comparison of the glucose concentrations of orange‚ lemon and grapefruit juice. Research: Benedict’s Reagent is a mixture of sodium compounds and copper sulphate. The copper ions are reduced by fructose (a reducing sugar) to form copper oxide‚ thus turning it from blue

1.0 ABSTRACT The production of reducing sugars by acid of carbohydrate cereals powder‚ jams (total sugar content) and jams (reducing sugar content) were performed in order to study reducing sugar production. The study involved hydrolysis carbohydrate cereals powder and jams by immersing in boiling water at environmental temperature. Acid hydrolysis was carried out through reflux boiling for 20 minutes with 10ml 0f 1.5M concentrations of diluted sulphuric acid. Reducing sugars concentrations

Acknowledgement I would like to express my sincere gratitude to my chemistry mentors Mrs. Smiti Gupta for her vital support‚ genius guidance and encouragement without which this project would not have come forth from my side. I would also like to express my heartly gratitude to the lab assistants Mr. Rajkumar Singh for his necessary suggestions and initiations during the making of this project. I am grateful to My Parents and My Sister whose blessings and wishes have gone a long way in the

Laboratory Order Form 1 DESIGN 1.1 Defining the problem Focus / Research question How does osmosis work and what effect will this have on the raisin at different sucrose concentrations? Hypothesis The raisin in the beaker with most diluted sucrose solution will gain the most mass‚ therefore the control (0% sucrose solution) should be the most successful (in relation to the aim.) Background Information / theory Osmosis may occur when there is a partially permeable membrane‚ such

Abstract Carbohydrates are important in metabolic processes for everyday physical and chemical actions. The carbohydrate‚ glucose‚ is a key component in generating adenosine triphosphate‚ also known as ATP. In order to analyze unknown glucose levels‚ a DNS assay was performed. By using 2-hydroxy-3‚5-dinitrobenzoic acid to oxidize the aldehyde group on the carbohydrate‚ the reducing end of glucose increases in absorbance of 540 nm. Using a UV spectrophotometer‚ the concentration was calculated
