The Four Types Of Macromolecules In The Human Body

Carbohydrates, proteins and lipids are known as macronutrients as the body needs masses of these nutrient components in order to carry out the bodies’ essential functions.

The most common macromolecules found in living organisms are lipids, carbohydrates, proteins and nucleic acids. Briefly, the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy, information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests, many cannot. Scientists then use certain tests to determine the presence of macromolecules.

On my current diet, I consume excessive amounts of refined carbohydrates and added sugars. These types of carbohydrates do not contain the necessary nutrients, needed by the body for optimal health. Also, consuming excessive amounts of these types of carbohydrates may result in obesity.

(Driskell 29) These simple carbohydrates are easily broken down, converted into glucose for the body and easily flow into the blood stream. The downside to this form of carbohydrates is that they are most common in the form of refined sugars or refined flours which retain very few vitamins after being processed. (“HealthStyle Fitness”) As the body uses this form of glucose a cycle begins which involves fluctuations of high and low blood sugar. This cycle works when blood sugar rises after the consumption of simple carbs and then as the blood sugar begins to drop the body demands more simple carbs to bring blood sugar levels back to up. The cycle that is formed essentially keeps the body from burning body fat because there is a continuous demand and consumption of simple carbohydrates. The second form of carbohydrates is that of complex carbohydrates which consist of polysaccharides, three or more monosaccharides. These complex carbs are found in the form of starch, fiber and glycogen (animal starch). Those complex carbohydrates consumed in the form of starch are found in plant foods like corn, wheat, potatoes, cereals, pastas, and beans. When they are broken down these carbs allow for the slow production and release of glucose into the blood stream and allowing for a consistent blood sugar level. (Guthrie 27) Dietary fiber is another form of complex carbs which are present in plant foods because fiber is

Carbohydrates are composed of carbon, hydrogen, and oxygen. Carbohydrates can come from fruits, vegetables, and grains. There are two different kinds of carbohydrates. The first being simple carbohydrates, which are sugars. Glucose, fructose, and galactose fall under the sugar category. Then you have your complex carbohydrates, which are starch in grains, glycogen stored in our muscles, and fiber. When it comes to energy within our body glucose is a major source of energy. When our body does not get enough carbohydrates to supply enough glucose, our body will make glucose from proteins. I applied this to my life by making sure I eat fruits, vegetables, and grains to get my carbohydrates every single

Carbohydrates are macromolecules which and contains carbon, hydrogen and oxygen (C,H,O). There are also two types of sugars, sweet soluble and starches which are non-soluble. Sugars can also be single or simple sugars.Carbohydrates can be found in a wide variety of foods such as pasta, wheat and grains, rice, potatoes, fruits and sugars. Carbohydrates are broken down into

This section will dealt with the main organic molecules in living things: carbohydrates, fats ( lipids ), proteins and nucleic acids.

Living in Hong Kong, a place where 90% of the food are imported from a place where everything can be a fake or contaminated, it is not uncommon to hear that governmental reports showing some food products are contaminated with some certain chemicals or pathogens and the public should avoid ingesting them. At the age of 6, I already knew that all daily food products are not 100% free of contamination, and one could not avoid eating anything. What I wondered was what those contaminations are and how they affect our bodies. This is the start of my fascination in toxicology. As I started learning science in elementary and middle school and learn about the macromolecules inside the body, I started to imagine how ‘macro’ they are when the molecule cannot be seen even with a microscope and why they can have distinct functions when they use the same word to describe their properties. (I did not know that protein is a type of molecules that can have different shapes at that time). Instead of memorizing these facts, I wished to know why and how the molecules interact with each other.

Most people ask are all carbohydrates bad? The simple answer to this question is no. There are two different types of carbohydrates; good and bad. Many people don’t realize this and this is often the cause of so many weight loss failures.

There are two types of carbs: simple carbs and complex carbs. Simple carbs are also known as simple sugars or refined sugars. These can be found in candy, but it is better to obtain them through fruit which also contain natural vitamins and nutrients. Complex carbs are also known as starches which are found in bread, rice, and pasta. These are rich in fiber which aids the digestive system and helps you feel fuller.

Start avoid processed carbohydrates in cookies, crackers, candies, baked goods, white rice, bread and pasta. We bring you a few tasty ideas that will help you in controlling carbohydrate intake.

Lipids are a diverse group of molecules that is hydrophobic, encompassing all fatty acids and their derivatives. They are essential in human life, functioning as a long term energy source, a heat insulator, and a membrane structure for cells and organelles. Fatty acids are a component of lipids, with a basic structure of a

Carbohydrates are loaded with vitamins, minerals, phytochemicals, fiber, and above all - they give your body the energy it needs for exercise - and muscle repair and growth. Breads, rice, cereal and pasta compose the starch list you should be opting for on a daily basis. These complex carbs deliver glucose which is then circulated to your body's cells to provide energy. Fibers in the forms of fruits and vegetables should also be consumed on a daily basis in order to provide your body with anti-oxidants while promoting proper digestion, bone building, and cholesterol

There are four types of biomolecules, carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are large chains of sugar found in food and living tissues. This includes sugars, starch, and cellulose. They have the same ratio of hydrogen and oxygen that water has, 2:1. They are broken down to release energy in the animal body. Lipids are any organic compounds that are fatty acids and don’t dissolve in water but do in organic solvents. Fatty acids can be found in natural oils, waxes, and steroids. Proteins are macromolecules that do everything in the cell. They are tools and machines that make things happen. Nucleic acids are long strands of nucleotides, and function primarily in storage and transmission of genetic information. There are two types of nucleic acids, DNA and RNA. DNA is the genetic material of all cellular organisms, and RNA sends out messages from the information that is held in the DNA.

All organisms have biological macromolecules that they cannot live without. In order to fully understand them, we categorize them into four major classes: carbohydrates, proteins, nucleic acids and lipids. One or more of these molecules are used in every biological process of life, including the cell cycle. Though different parts of the cell cycle rely on one or more of the four major macromolecules, they are all involved in fulfilling the duties of the cycle.
