Our bodies break down starch into the individual glucose units‚ which are further metabolized into CO2 and water through the process of glycolysis—this is the process we commonly call digestion. The enzyme amylase is present in our saliva and begins the process of digestion when starch containing foods enter our mouths. In this lab you will measure the amount of amylase present in your saliva by monitoring the breakdown of starch. Introduction: You can probably name a variety of foods that are referred to as “starchy”

“Carbohydrates in our Life” The cells are composed of biomolecules that are needed in order for us to live‚ one of which are carbohydrates. Most people tend to think that carbohydrates are fats but that is not the correct way of thinking about it. Truthfully‚ these are all just fallacies. In fact‚ carbohydrates or in scientific terms called as “saccharides” serves as fuel and energy storage in our body. It can either be classified as simple or complex and is composed of carbon‚ hydrogen and oxygen

Cell membranes are a bilayer make up of phospholipids‚ proteins‚ and cholesterol. Its main function is to regulate what comes in and out of the cell by means of diffusion‚ transport proteins and protein channels. Trans membrane proteins transport polar solutes across hydrophobic regions of the bilayer. Diffusion occurs when solutes are transferred from a high concentration of that solute to a lower concentration of solutes. Solutes do not depend on the concentration of other solutes‚ which allows

Practical 1 : Carbohydrates Introduction : Carbohydrates are important to human life ‚ this practical is to investigate physical ‚ functional and sensual properties of different carbohydrates ‚ including monosaccharides and disaccharides . Experiment 1 Title : Relative Solubility of Carbohydrates ‚ Glucose ‚ Galactose and Lactose . Objective : To determine the relative solubility of glucose ‚ galactose and lactose by measuring their saturation point at the same constant temperature.

Without a good supply of carbohydrates as glycogen in the muscles and liver‚ and frequent supplies with food and drink‚ it reduces the amount of time that can be sustained a moderate or intense physical effort. Who takes part in events that last for over an hour must pay particular attention to supply meals and snacks rich in carbohydrates. Dehydration impairs performance and athletes should not lose more than 2% of body weight during

The aim of the experiment is to investigate the effects of carbohydrate receptors in the mouth on exercise performance during a simulated time trial. Energy is required in the body for metabolic processes‚ physiological functions‚ muscular activity‚ heat production‚ growth and synthesis of new tissues. Carbohydrates have been researched and studied for centuries and are commonly viewed as a substrate for fuel metabolism‚ associated with many other energy-demanding processes. There has been extensive

It was stated in a Diabetes Forecast article‚ Researchers at Stanford University made a splash in the diet and nutrition world last March when they reported that in a 1-year study of 331 women‚ participants lost more weight on the controversial low-carbohydrate Atkins diet than popular rivals such as the Zone‚ Ornish‚ or

Optimal strength and endurance during your workouts it is very important that these glycogen supplies are completely restored before starting a new workout. The best moment to replenish exhausted glycogen supplies is during the first 2 hours after the workout.

We have four important macromolecules; carbohydrates‚ lipids‚ proteins‚ and nucleic acids. From these four‚ the macromolecule I chose for this assignment was carbohydrate. Carbohydrates branch off into three main categories; monosaccharides‚ disaccharides‚ and polysaccharides. I decided to focus on disaccharides‚ specifically sucrose. Sucrose is more commonly known as table sugar. It has a chemical formula of C12H22O11. It is physically described as a white‚ odorless (although when heated‚ it may
