The Structure and Function of Carbohydrates Large biological molecules are called macromolecules, there are giant molecules (polymers) made up of repeating units (monomers). Carbohydrates are one of the main classes of biological molecules. Macromolecule units (monomers) are joined together by condensation reactions and hydrolysis reactions split macromolecules down into their individual units. Carbohydrates are molecules that contain elements of carbon, hydrogen, and oxygen. Carbohydrates have a 2:1 hydrogen to oxygen ratio, there are twice as many hydrogen atoms as oxygen atoms (the same proportion as in water). Carbohydrates are categorised in three many groups: Ø Monosaccharide – monomers and therefore contain single surgar. Ø Disaccharide – contain double sugars. Ø Polysaccharide – are large molecules containing many complex sugars. The general formula for carbohydrates is Cx(H20)y. Monosaccharides are white crystalline solids with low molecular mass and sweet tasting. All monosaccharides are reducing sugars because they all aldehydes. Different monosaccharides contain different number of carbon atoms. There are three types of monosaccharides, trioses, pentose and hexose. They generally contain three (trioses), five (pentoses) or six (hexoses) carbon atoms. Triose is used as a product in biochemical pathways of respiration and photosynthesis. An example of pentoses is ribsomes and deoxyribsome. These sugars are found in the nucleic acid of DNA and RNA. Examples of hexoses are glucose and fructose. It is an important source of energy in respiration found in many sweet tasting fruits. There are four different types of hexose sugars. The slight differences in the way their atoms are arranged give them slightly different properties. These are shown below: α-glucose: β-glucose: Galatose: Fructose: [IMAGE] [IMAGE] The main function of monosaccharide is that they are able to move through bodies, gut walls and therefore important as a source of energy. All other carbohydrates have to be converted to monosaccharides before energy can be released and its is due to it’s small size they are very soluble and it is the form of monosaccharides that all carbohydrates are carried in the blood.

One of the four molecules is carbohydrates. Carbohydrates are made out of CHO. The main building blocks are sugars (saccharides). What carbohydrates do for us is they store fuel for our cells. They are fast energy. Glucose, fructose, and galactose are examples of single or simple sugar molecules or monosaccharide. Maltose, sucrose, and lactose are examples of two sugar molecules linked, also known as disaccharide. Starch, glycogen, and cellulose are examples of many sugar molecules linked. They are also called polysaccharide. If you wanted to test if there were carbohydrates in something you could do the sugar or the starch test.
Differentiating between fatty acids can be in two main ways: the length of free fatty acid chains and the fatty acids degree of saturation. The number of carbon atoms determine the length of fatty acid chains which often categorized as short chain fatty acids (SCFA), Medium-chain fatty acids (MCFA), Long-chain fatty acids (LCFA), and Very long chain fatty acids (VLCFA) with aliphatic tails longer than 22 carbons, while the number of double bonds between carbon atoms determine their degree of saturation. Fats can be categorized into saturated fats and unsaturated fats. Furthermore, the unsaturated fats divide into monounsaturated fats and polyunsaturated fats. Fatty acid can be saturated if there are no double bonds
The primary method to control gestational diabetes mellitus (GDM) is through dietary regulation. The most effective method to control GDM via diet is through carbohydrate restriction and/or selectivity. It is recommended that pregnant women with GDM reduce their carbohydrate intake to 40% of the total caloric intake or can maintain a 60% carbohydrate intake but those carbohydrates must all come from low glycemic index foods. Examples of low glycemic foods are apples, spinach, black beans, split peas, oatmeal, and quinoa. Additional suggestions are to eat complex carbohydrates instead of simple, refined sugars. Eat small, frequent meals and snack often in between meals in order to maintain constant glucose levels throughout the day.
Carbohydrates are biomolecules that consist of a chain or ring of carbon atoms attached to hydrogen and oxygen atoms. The simplest formula for carbohydrates is (CH2O)n. Carbohydrates are important to organisms for a variety of reasons. They are used to form the structural components of the cell, aid in energy storage, and serve as intermediary compounds for more complex molecules. Carbohydrates are classified as either monosaccharides, disaccharides, or polysaccharides. Both monosaccharides and disaccharides dissolve easily in water. Carbohydrates are produced in plants through the process of photosynthesis and animals obtain these carbohydrates by eating the plants. ("BIO 1510 Laboratory Manual," 2016)
Lipids and Carbohydrates Lipids are a group of substances, which include fats, oils and waxes. Carbohydrates include sugars, starches, glycogen and cellulose. They are stored in plants as starches and in animals as glycogen. There are many differences between carbohydrates and lipids.
There are many kinds of carbohydrates; monosaccharides, disaccharides, and polysaccharides each containing a certain number of sugars in them. Monosaccharides are classified by the number of carbons in its carbon skeleton. Some examples of a monosaccharides are glucose, which is basic sugar, fructose, and hydroxyl. Disaccharides (which are built from monosaccharides) include sucrose, lactose, and maltose, which are all forms of sugars. Lastly, polysaccharides are made from both monosaccharides and disaccharides, these inclu...
For my research project I chose Molecular Gastronomy because I think it will benefit me in the future as I would like to be a chef. Molecular Gastronomy is the science that changes the chemical and physical appearance of food. I chose to research "To what extent is Molecular Gastronomy practical in the home kitchen". This was because I wanted to see if it was possible to recreate Molecular Gastronomy in the home kitchen and if it is really worth the trouble. The research methods I used were interviews, surveys, internet articles, books, you tube and experiments.
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 classified by the number of carbon atoms in the molecule; trioses have three, tetroses four, pentoses five, hexoses six, and heptoses seven. Most contain five or six. The most important pentoses include xylose, found combined as xylan in woody materials; arabinose from coniferous trees; ribose, a component of ribonucleic acids and several vitamins; and deoxyribose, a component of deoxyribonucleic acid. Among the most important aldohexoses are glucose, mannose, and galactose; fructose is a ketohexose.
Every food that people eat has molecules just like one of your favorite foods like pizza which has molecules. Trees, plants, animals and even humans have molecules. There is more than one type of atoms that you know of. There are four types of atoms are Carbon, Hydrogen, Oxygen and Nitrogen. An easier way to say all the atoms in one word is CHON which stands for Carbon, Hydrogen, Oxygen and Nitrogen.
The food we consume is for a purpose - energy. Some foods are better than others at producing energy, while foods like monosaccharides and disaccharides are ‘sweeter’ or ‘taste better’ but aren’t as efficient. These are known as simple sugars. Monosaccharides are one molecule of simple sugar. They don’t need to be broken down to be energy and are found in foods like fruits, cane sugar, and beans. Alternatively disaccharides are two molecules of bonded monosaccharides. This means that they have broken down into energy adenosine triphosphate (ATP) but they are still simple sugars. Though you can often associate highly processed foods with disaccharides they are also found in milk.
Carbohydrates are compounds of carbon, hydrogen, and oxygen, which provide the body with energy when they are broken down in cellular respiration (LABS-AIDS INC., 2012). Starches and sugars are considered two carbohydrates. Our bodies use carbohydrates to make glucose also known as sugar, which gives you energy and helps keep everything going. Our bodies use glucose immediately or stores it in our liver and muscles for when it is needed. Carbohydrates found in fruits, vegetables, grains (cereal, breads, etc.), milk, and foods with added sugars. The foods that contain added sugars, such as cakes and cookies, are considered to be “bad” carbs in most cases. “Good” carbs can be found in natural foods, such as strawberries and bananas.
Carbohydrates are divided into two groups, simple carbohydrates and complex carbohydrates. Simple carbohydrates, sometimes called simple sugars, include fructose (fruit sugar), sucrose (table sugar), and lactose (milk sugar), as well as several other sugars. Fruits are one of the richest natural sources of simple carbohydrates.
Carbohydrates - the main role of a carbohydrate is to provide energy, this is because they are the body's main source of fuel, which is needed for physical activity, brain and operation of the organs. All the tissues and cells in the body need carbs but not only that they are also important for intestinal health. Carbohydrates are biological molecules that contain carbon(c), hydrogen(H) and oxygen(O) atoms. Monosaccharides are the simplest unit of carbohydrates and the simplest form of sugar.
The bulk of our diets should be carbohydrates because of the importance that they serve on the body. Carbohydrates give our bodies fuel and energy that allows the rest of our body to function properly. The only other nutrients that fuel our bodies are protein and fats, which have their disadvantages. Protein when consumed in an excess amount actually is not helpful. While fats are only used as fuel by certain areas in the body. Our brains and nervous systems do not find fats to be useful when conducting energy. Carbohydrates not only provide energy for the body but they also help with glucose storage, raw materials, structures and functions, digestive tract health, blood cholesterol, blood glucose, satiety, and body weight.
