1.0 Title Determination of Protein Content Using Kjedahl and Titration 2.0 Introduction Proteins are polymers. They are the source of dietary amino acids and are used for growth and maintenance of living systems. They are costlier sources of energy compared to carbohydrates and fats and hence the human body utilizes proteins mainly for biosynthesis rather than as an energy source‚ though the energy yield is 5 kcal/g of protein. Twenty different types of amino acids occur naturally in proteins

“Pineapple peelings as vinegar” “Pineapple peelings as vinegar” *Abstract*- The pineapple ( Ananas comosus) is a tropical plant and fruit (multiple)‚ nativeto Uruguay‚ Brazil‚ and Paraguay. It is a medium tall (1±1.5m) Herbaceous perennialplant with 30 or more trough-shaped and pointed leaves 30±100 cm long‚ surrounding at hick stem. The pineapple is an example of a multiple fruit: multiple‚ spirally-arranged flowers along the axis each produce a fleshy fruit that becomes pressed against the

pH pH means Power of Hydrogen or Potential of Hydrogen. pH is a scale of acidity from 0 to 14. It tells how acidic or alkaline a substance is. More acidic solutions have lower pH. More alkaline solutions have higher pH. Substances which are not acidic or alkaline i.e neutral usually have a pH of around 7. Acids have a pH less than 7. Alkalis have a pH greater than 7. There are a lot of ways for finding the pH of something. One way is to use litmus paper. The pH paper is able to tell how strong

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 were determined by spectrophotometry using the 3

THE EFFECTS OF AMMONIA AND VINEGAR ON RADISH PLANTS 1 The Effects of Ammonia and Vinegar on Radish Plants THE EFFECTS OF AMMONIA AND VINEGAR ON RADISH PLANTS 2 Abstract INTRODUCTION OF GROUP Plants are one of the most complex organisms; how they grow is very complex and it is important to see how they grow to even how they die. We first had to propose a question and test it to see if it was profound enough to test. Our group decided to see how different chemical

Investigatory Project (Pineapple Peelings to Vinegar) Introduction A. Background of the Study A Pineapple is a fruit wherein you have to peel off the peelings to eat it‚ like any other fruits. The researchers chose this as their project to prove that Pineapple peelings have other uses. The researchers also noticed that the families in our country are very practical nowadays. Instead of throwing the peelings away‚ many families can earn something from it by using our experiment. They can produce a product

Vitamin C Introduction: The lab consists in determining the vitamin C concentration in a solution by a redox titration using iodine. Vitamin C (ascorbic acid) is a water-soluble‚ essential oxidant that plays a vital role in the protection of the body from infections and disease it is acquired from primary fruits and vegetables. With the use of different materials as natural orange juice‚ Tampico (chemical orange juice) and other solutions that contain vitamin C we will find the amount of vitamin
