characterization. B. Albumin from egg Egg white is acquired because it is where albumin is present. It is gently stirred to prevent denaturation and to mix the enzymes present in it. Later on‚ it is added with 1.0 M HOAc to remove calcium anions present. Then‚ it is sent to the centrifuge. The precipitate collected is discarded because it contains contaminants which aren’t needed for the experiment. Also‚ according to Campbell‚ if the

body. The things we eat turn into things such as carbohydrates‚ fats‚ and proteins. Carbohydrates are‚ any of a large group of organic compounds occurring in foods and living tissues and including sugars‚ starch‚ and cellulose. Protein‚ such as meat‚ eggs‚ and beans‚ consist of large molecules of protein that must be digested by enzymes before they can be used to build and repair body tissues. An enzyme in the juice of the stomach starts the digestion. Further digestion

I found myself pleasantly surprised with the remarkably improved quality from its American counterpart. My friend convinced me to try a latte and an egg sandwich. After that‚ every time I walked past a McDonald’s I looked forward to stopping‚ especially for a latte. I have only purchased an American McDonald’s coffee once since

Experiment 2: Food Tests Objective * To study the presence of reducing sugars. * To study the presence of protein. Introduction In this experiment‚ glucose‚ maltose‚ lactose and sucrose are used for testing reducing and non-reducing sugars. Glucose is monosaccharide while maltose‚ lactose and sucrose are disaccharides of carbohydrates. Monosaccharaides are the monomers which make up all other carbohydrates and cannot be broken into smaller molecules by hydrolysis. Disaccharides are
