levels and glucose use are in fact increased‚ but hyperglycaemia that is not necessarily resolved by the use of exogenous insulin is present. This appears‚ to some extent‚ to be driven by an elevated glucagon to insulin ratio. To support hyper-metabolism and increased gluconeogenesis‚ fat is mobilized from adipose stores to provide energy (lipolysis) as the result of elevated levels of catecholamine along with concurrent decrease in insulin production. If hyper-metabolic patients are not fed during

with discretion; opt for carbohydrates with a low glycemic index (GI). GI is the property of a carbohydrate to be converted into blood sugar. A low GI indicates that a carbohydrate takes longer to be converted to sugar‚ thus implying that it is contains insoluble fiber that is tougher to break down (that’s good news‚ intestines need some exercise too). While consuming carbohydrates‚ watch out for the glycemic load (GL) too. Glycemic load accounts for how much carbohydrate is in the food‚ and how much

The structure and function of carbohydrates A carbohydrate is an organic molecule containing only Carbon‚ Hydrogen and Oxygen with the general formula Cn(H20)n. They are made up of individual molecules called monomers which are joined together by condensation reactions to make a longer chain called a polymer. Carbohydrates are categorised in to three main groups; monosaccharides‚ disaccharides and polysaccharides. Monosaccharides are single sugars and are sweet tasting soluble substances such

Getting Lean With Carb Cutter? Many Americans have turned to diet pills. Should you? In the United States today many people have supposedly lost weight with certain pills. One of these pills is called carb cutter. Carb Cutter claims to inhibit the activity of the starch-digesting enzyme‚ amylase. When the diet pill binds to the amylase‚ it prevents the breakdown of starch. In the Biology 1103 lab‚ we conducted two experiments to determine whether or not the diet pill‚ Carb

Nutrients- substances in foods that provide energy and form body tissue necessary for life and growth. -Carbohydrates- sugars‚ starch and fibre -Fats- main form of energy storage in the body -Proteins- amino acids require to build and repair body structures and to regulate processes in the body Part ll 1.

Organic molecules are the molecules of life that include Carbon and Hydrogen. Organic molecules consist of four important classes which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing

OBJECTIVE: 1. To distinguish the bacteria abilities to metabolize various substrates and end products formed. 2. To observe the growth of different bacteria species in term of structures and its morphology based on different chemical substance applied. 3. To observe physiological and immunological properties utilized by different species of bacteria.

structural units linked together by covalent bonds‚ giving them a variety of structures and functions in the body. Macromolecules (also known as supermolecules) are commonly grouped into four major categories: proteins‚ nucleic acids‚ lipids and carbohydrates. These are mainly composed of polymers‚ long molecules made up of a large number of small‚ similar molecules‚ or monomers. Proteins are polymers of amino acids. Long amino acid chains are folded into complex shapes‚ the shape of each determining

The study of metabolism reaches as far back as the thirteenth century. With it‚ things like the citric acid cycle‚ mitochondrial physiology‚ and diseases like diabetes have been better understood. The overall concept of metabolism is key in any biological field and it helps ensure the survival of an organism. It does so by converting things like food that we ingest into energy via a series of somewhat complex biochemical reactions. This energy can then be used for a multitude of things including

There are four types of macromolecules: carbohydrates‚ proteins‚ lipids and nucleic acids. In this lab we will test four foods to see if they contain carbohydrates (sugar and/or starches)‚ proteins and lipids. We will use chemical reagents to test to determine the presence of macromolecules: Benidicts solution for sugar‚ Iodine for starch‚ Biurets reagent
