Biology Laboratory Report Practical 4 Food tests Introduction The main components of food are proteins‚ fats‚ carbohydrates‚ and‚ of course‚ water. Proteins‚ lipids and carbohydrates are carriers about energy necessary for vital activity. They are a plastic material for the formation of structures of the body‚ as well as used for the synthesis of hormones and substances that transmit signals in the nervous system. Our food also includes food (plant) fibers‚ has recently seemed unnecessary ballast

restriction of dietary carbohydrates. The Atkins Diet eliminates fruits‚ cereals‚ breads‚ grains‚ starches‚ baked goods‚ dairy products‚ starchy vegetables and sweets. During the initial two-week induction of the Atkins Diet‚ only pure proteins are allowed. Pure proteins include‚ meat‚ fish‚ shellfish‚ poultry and eggs‚ along with pure fats such as butter‚ olive oil and mayonnaise. A total of 20 grams of carbohydrates is allowed during this initial 2-week period. These carbohydrates in include‚ vegetables

Project Proposal Rationale There are many levels of carbohydrates in different kinds of milk. The carbohydrate levels in milk can determine which milk is the healthiest. Milk contains carbs and the amount of carbs can affect a diet. RESEARCH QUESTION(S)‚ HYPOTHESIS(ES)‚ ENGINEERING GOAL(S)‚ EXPECTED OUTCOMES: How is this based on the rationale described above? What is the problem or purpose to be addressed? Can the difference of milk and carbohydrate levels determine which type of milk is healthier

Aldehyde and Ketone 1. ALDEHYDE Definition: An aldehyde is an organic compound containing a formyl group. This functional group‚ with the structure R-CHO‚ consists of a carbonyl center (a carbon double bonded to oxygen) bonded to hydrogen and an R group‚ which is any generic alkyl or side chain. The group without R is called the aldehyde group or formyl group. Aldehydes differ from ketones in that the carbonyl is placed at the end of a carbon skeleton rather than between two carbon atoms

The two food substances that had the most were butter and starch. The organic compounds that are most common in foods that come from plants are carbohydrates. However‚ the organic compounds that are most common in animal meat are proteins. The original colors of the food substances did affect our test results. For example‚ if the substance was yellow‚ such as apple juice‚ and we were trying to test

In biology‚ there are four major biological macromolecules that are found in the cell‚ carbohydrates‚ lipids‚ nucleic acid‚ and proteins. Biological macromolecules are also known as organic molecules. Biological macromolecules are very large molecules that are of a key importance to living organisms. Most biological macromolecules are built by joining smaller molecule subunits. Carbohydrates are large groups of organic compounds found in foods such as sugars‚ starches‚ glucose‚ fructose‚ galactose

Name:_________________________________ Nutrition Label Analysis When we read a nutrition label‚ the Calories tell us how much energy is stored in our food. Energy in food comes from 3 sources: fat (lipids)‚ protein‚ and carbohydrates. You will be analyzing the nutrition facts of an item to determine how much of the energy (Calories) comes from each type of carbon-based molecule. 1. How many grams of lipids (fat) are in your item? _________________________________________________________________________________________________

health conscious or health enthusiasts prefer to stick to a low carb diet which basically means cutting out fruits‚ cereals‚ grains and sugar from the diet.A low-carb diet is a diet that restricts carbohydrates‚ such as those found in sugary foods‚ pasta and bread. It is high in protein‚ fat and healthy vegetables. There are many different types of low-carb diets‚ and studies show that they can cause weight loss and improve health. Sources of Low carb diet: Meat: Beef‚ lamb‚ pork‚ chicken and others

cells that transfer the fuel from food into the energy needed in everyday life to complete daily activities. Energy is needed to get rid of oxygen from certain areas in our bodies and remove it from our bloodstream. Energy comes from; Fats Carbohydrates proteins Without energy stored in our bodies- our bodies would not function properly at all every human being needs energy to survive. Energy’s role in our body consists of the breakdown of large molecules to release energy‚ this is called
