added iodine into starch‚ the result was the starch solution turned dark blue. Starch had a positive result is because of the complex of iodine stuck inside the amylase coil which produced a characteristic purple - black color (Elservier Science Publishers‚ 1988). Also‚ starch was composed of polymers of glucose and long linear chains were amylase (Alberts Bray‚ Hopkin Johnson‚ Lewis Raff‚ Roberts Walter‚ 2009). The Benedict’s test for reducing sugars was used to determine the presence of reducing

macromolecules? Carbohydrates (monosaccharides & polysaccharides)‚ lipids‚ proteins‚ & nucleic acids. 4) What is the original colour of iodine‚ and what colour does it turn in presence of starch and glycogen? Starch: yellow --> blue-black (amylase in starch reacts with iodine) Glycogen: yellow --> reddish-brown (due to the multi-branched component) 5) How do plants and animals store simple sugar glucose? In the form of polysaccharides. In plants‚ starch is the polysaccharide with glucose

has had a fever for 3 days and has complained of fatigue. Tests: Blood tests revealed high levels of triglyceride (hypertriglyceridemia) and increased calcium levels (hypercalcemia) and hyperlipidemia (excess levels of fat in the blood). Blood amylase levels slightly elevated and decrease in insulin levels also her lipase concentrates were elevated. Ct scan was positive for a psuedocyst. We used a stethoscope to listen for bowel sounds. None were present. Due to the test results patient is diagnosed

The Digestive System Structure and Functions Jermaine Kendrick Vista College The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary canal is made up of the oral cavity‚ pharynx‚ esophagus‚ stomach‚ small intestines‚ and large intestines. In addition to the alimentary canal‚ there are

Digestion is a process in which the food that we eat is broken down into tiny nutrients to be taken in by the body. Within the human digestive system‚ chemical and physical reactions occur that allow for the digestion and the absorption of proteins into the bloodstream. The purpose of this paper is to show how chemistry relates to the daily functions within the body. There are two types of digestion processes‚ which are called mechanical and chemical digestion. Mechanical digestion includes the

The Pancreas The pancreas is probably one of the few organs that we really do not pay close attention to‚ but it is a very vital organ. The pancreas is a part of the digestive system. It is the largest organ in its system. It plays life sustaining roles in the regulation of food digestion and blood glucose levels. The anatomy of the pancreas helps us to understand each part and each section and how it pertains to the body. It is also very to study the physiology‚ because it tells us the functions

(American College of Gastroenterology‚ 2016) Abdominal pain‚ nausea‚ and vomiting are symptoms of acute pancreatitis. The abdominal pain is usually in the epigastric region radiating to the back. This is accompanied by elevated serum levels of amylase‚ lipase‚ or both and by radiographic evidence of pancreatic inflammation‚ edema or necrosis. Although pancreatic morphology and function may recover after an episode‚ complete recovery is unlikely if the initial damage is substantial‚ particularly
