Abstract Carbohydrates are the most abundant organic compounds in the plant world. They act as storehouses of chemical energy (glucose‚ starch‚ glycogen); are components of supportive structures in plants (cellulose)‚crustacean shells (chitin)‚ and connective tissues in animals (glucosaminoglycans); and are essential components of nucleic acids (D-ribose and 2-deoxy-D-ribose). Monosaccharides‚ oligosaccharides‚ and polysaccharides are theclassifications of carbohydrates. This experiment involves

Carbon‚ Hydrogen and Oxygen. These three simple elements make up one of the most useful substances for many living organisms: Carbohydrates. Carbohydrates are used for numerous processes in organisms from acting in important roles of cellular recognition in the human body to storing chemical energy in plants in the form or starch. The roles of carbohydrates in the human body alone are numerous; providing energy for working muscles‚ providing energy for the regulation of blood glucose‚ preventing

Even though carbohydrates are good for your body too much of it can upset the delicate balance of your body’s blood sugar level which can result in fluctuation in energy and mood that leave you feeling irritated and even tired.

Digestion and Nutrients Briana Smallwood The human body needs nutrients for it to survive. Nutrients are the fuel for the body to do work. It helps the body grow‚ provide protection from sickness and disease‚ function properly‚ and even live. There are many types and forms of nutrients that each do specific or multiple jobs. They are classified in six main groups. Carbohydrates‚ proteins‚ fats‚ vitamins‚ minerals and water are all the different groups. Proteins are nutrients that help build and

Carbohydrate Metabolism Carbohydrate metabolism starts with digestion in the small intestines. This is the site where monosaccharides are absorbed into the blood stream. This type of metabolism is basically considered to be glucose metabolism because carbohydrates are eventually broken down into glucose so that it can diffuse into the blood stream. There are three hormones in the body that control the concentration on glucose in the body: Insulin‚ glucagon‚ and epinephrine. If sugars are too

Energy in context Introduction Digestion is the breakdown of large insoluble food molecules into smaller molecules so they can pass though the intestinal wall into the bloodstream and be transported throughout the body. There are seven different food groups in a balanced diet which should include Carbohydrate‚ fat‚ water‚ protein‚ fibre‚ vitamins and minerals. Although most foods contain these in some shape or form the foods that contain most of one type fall into that category‚ a chicken

Human Digestion April 27th‚ 2014 SCI/241 Erica Leath The digestive system is a very interesting process that takes place after we have eaten a meal or a snack. The digestive system is responsible for breaking down the food that we have eaten and sending the nutrients to the different places in the body. The digestive is so amazing because it recognizes what your body needs and does not need and understands how to separate the two. Just like everything else in our body‚ the digestive

What are Carbohydrates? Carbohydrates are the sugars‚ starches‚ and fibers found in fruits‚ grains‚ vegetables and milk products. Carbohydrates are sugars that break down inside the body to create glucose. Glucose is moved around the body in the blood and is the primary source of energy for the brain‚ muscles‚ and other essential cells. There are two types of carbohydrates‚ simple and complex; Simple carbohydrates refer to sugars with a simple molecular construction of one or two parts. Because
