The main purpose of carbohydrate loading is to reestablish both the glycogen of the muscles and liver in order to keep hunger away during some types of competitive sports. These types of competitive sports include: marathons‚ long distance swimming‚ and cycling. Carbohydrate loading is done anywhere from a week out from a competition or event to only twenty four hours before. There are three main benefits to carb loading for athletes of sports like marathons‚ long distance swimming‚ cycling‚ and

Edward F. Coyle’s article‚ Fat Metabolism During Exercise: New Concept‚ focuses on answering the question to “what limits the rate at which people can convert their body fat into energy during exercise. He focuses on the different components of fats‚ such as the adipose tissue‚ blood plasma‚ and the oxidization of fats. He highlights how within the adipose tissue there an estimated 50‚000 to 60‚000 kcal energy stored as triglyceride and an obese individual will have more energy than compared to an

Organic Chemistry/Biochemistry 1: Compounds Important to Life • Biologists classify compounds into organic compounds and inorganic compounds. Organic Compound: a compound that is derived from living things and contains carbon Inorganic Compound: a compound generally derived nonliving things • Water Water is an inorganic molecule with unique properties that make it one of the most important compounds for living things. In the water molecule (H2O)‚ the hydrogen and oxygen atoms bond

Monosaccharide also called SIMPLE SUGAR‚ any of the basic compounds that serve as the building blocks of carbohydrates. Monosaccharides are polyhydroxy aldehydes or ketones; that is‚ they are molecules with more than one hydroxyl group (-OH)‚ and a carbonyl group (C=O) either at the terminal carbon atom (aldose) or at the second carbon atom (ketose). The carbonyl group combines in aqueous solution with one hydroxyl group to form a cyclic compound (hemi-acetal or hemi-ketal). Monosaccharides are

CHAPTER 1 Cell Structure and Organisation Cells * All living organisms are made up of cells * The simplest living organisms have one cell only * His name is unicellular-e.g. bacteria. * Most other living organisms have many cells- his name is multicellular- e.g. Man‚ plants‚ animals. * Cells can be seen only under microscope Cell structure All cells have the following structure in common: a) Cell membrane- a very thin layer of protein and fat‚ surrounding the cell.

energy. The breakdown of fats is not instant because skeletal muscle has to receive the fatty acids from the blood to break it down. In the fifteen minutes‚ the body has to tap into a fuel source so sustain the energy and that fuel source is the glycogen and glucose (which is located in the skeletal muscle). Frielander‚ Casazza‚ Horning‚ Buddinger‚ and Brooks reported that throughout the hour of the exercise all the subjects reported an increase in glycerol. This data shows true with what was seen

Living organisms are composed of part water and part chemicals. The chemicals that help make up life are constructed mainly of carbon. A compound that has carbon in its composition is called an organic compound. Organic compounds also usually contain hydrogen atoms. Even though life is very complex‚ all large molecules that make up life are categorized into four large classes: lipids‚ protein‚ carbohydrates‚ and nucleic acids. These four molecules are known as macromolecules‚ due to their large size

Nutrition notes 9-17-2013 Chapter 5 ** Fat from fat stores and muscle glycogen provides most of the energy to fuel muscular work (physical activity) ** About 95% of the lipids in foods and in the human body are triglycerides. ** The fatty acids in foods influence the composition of fats in the body. ** Fats are a mixture of saturated monounsaturated and polyunsaturated fatty acids. ** Lipids that are firm at room temperature are called fats‚ and lipids that are liquid at room
