Carbohydrates, proteins, and nucleic acids are built from small molecular units that are connected to each other by strong covalent bonds. The small molecular units are called monomers (mono means one, or single), and they are linked together into long chains called polymers (poly means many, or multiple).

Why are carbohydrates lipids proteins and nucleic acids important?
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions. Combined, these molecules make up the majority of a cell’s dry mass (recall that water makes up the majority of its complete mass).5 mar. 2021

What do carbohydrates lipids proteins and nucleic acids have in common?
Carbohydrates and lipids are made of only carbon, hydrogen, and oxygen (CHO). Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P).
What are polymers of carbohydrates?
The most common carbohydrate polymers that are found in nature are cellulose, starch, dextrins and cyclodextrins, chitin and chitosan, hyaluronic acid, and various gums (carrageenan, xanthan, etc.).6 sept. 2019
What are the 4 natural polymers?
Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.
What is the main function of carbohydrates in your body?
Introduction. Alongside fat and protein, carbohydrates are one of the three macronutrients in our diet with their main function being to provide energy to the body. They occur in many different forms, like sugars and dietary fibre, and in many different foods, such as whole grains, fruit and vegetables.14 jan. 2020
What are nucleic acids function in the body?
Nucleic acid is an important class of macromolecules found in all cells and viruses. The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.
Which is the main use of carbohydrates in cells?
Energy Production The primary role of carbohydrates is to supply energy to all cells in the body. Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Some cells, such as red blood cells, are only able to produce cellular energy from glucose.13 août 2020
What are the three classes of carbohydrates?
1. Sugars. They are also called simple carbohydrates because they are in the most basic form.
2. Starches. They are complex carbohydrates, which are made of lots of simple sugars strung together.
3. Fiber. It is also a complex carbohydrate.
Is RNA made of protein?
Together, RNA, short for ribonucleic acid, and DNA, short for deoxyribonucleic acid, make up the nucleic acids, one of the three or four classes of major “macromolecules” considered crucial for life. (The others are proteins and lipids. … RNA and DNA are made up of subunits called nucleotides.15 oct. 2020
How do lipids nucleic acids and proteins differ from carbohydrates?
Proteins are different from fats and carbohydrates due to the presence of nitrogen, carbon, hydrogen, and oxygen in them. Carbohydrates only contain carbon, hydrogen, and oxygen whereas fats contain fatty acids which contain a carboxyl group and an alkyl group, thus containing only carbon, oxygen, and hydrogen.
What are the 5 elements of nucleic acids?
Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P).13 août 2020
Do lipids include steroids?
Steroids. Steroids are another class of lipid molecules, identifiable by their structure of four fused rings. Although they do not resemble the other lipids structurally, steroids are included in lipid category because they are also hydrophobic and insoluble in water.
What chemicals make up carbohydrates?
Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution, etc., are known as carbohydrate derivatives and may contain other elements.26 sept. 2014
