Proteins, nucleic acids, and most carbohydrates (the polysaccharides) are macromolecules formed by the joining (polymerization) of hundreds or thousands of low-molecular-weight precursors: amino acids, nucleotides, and simple sugars, respectively.

What is the difference between polysaccharides and nucleic acids?
Cellulose, a polysaccharide ( poly meaning many, and saccharide referring to sugar), is classified as a carbohydrate. It is found in the cell wall of plants. Nucleic acids are molecules found in the nucleus and help with genetic material, like what DNA does for us.10 nov. 2015
Do polysaccharides have proteins?
Polysaccharides are carbohydrates, long chains of monosaccharides, made of carbon, hydrogen, and oxygen, often in a 1:2:1 ratio. Polypeptides are proteins, long chains of amino acids, made of carbon, hydrogen, oxygen, nitrogen, and a variety of other element, not in a particular ratio.2 août 2014
What elements are found in proteins and nucleic acids?
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). The body also needs trace amounts of other elements such as calcium, potassium, and sulfur for proper functioning of muscles, nerves, etc.
What’s an example of nucleic acids?
Two examples of nucleic acids include deoxyribonucleic acid (better known as DNA) and ribonucleic acid (better known as RNA). These molecules are composed of long strands of nucleotides held together by covalent bonds. Nucleic acids can be found within the nucleus and cytoplasm of our cells.25 jan. 2020
What is the function of nucleic acids?
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.
What do polysaccharides nucleic acid and proteins have in common?
A. none of them are polymersB. they all contain nitrogenC.7 jan. 2019
Are nucleic acids Heteropolymers?
DNA is HETEROPOLYMER . HETEROPOLYMER made of AMINO ACIDS. While a nucleic acid like DNA or RNA is made of only 4 types of nucleotide monomers, Upvote | 7.
How are nucleic acids and proteins similar?
Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.13 août 2020
What is the difference of proteins and polysaccharides?
The main difference between proteins and polysaccharides is that proteins are composed of amino acids, while polysaccharides are composed of long chains of sugar molecules. On a smaller scale, proteins are synthesized from long chains of peptides to form their primary structure.24 juil. 2020
What are the function of polysaccharides?
Polysaccharides generally perform one of two functions: energy storage or structural support. Starch and glycogen are highly compact polymers that are used for energy storage. Cellulose and chitin are linear polymers that are used for structural support in plants and animals, respectively.
What foods contain polysaccharides?
Food sources Polysaccharides comprising up to 10 000 closely packed glucose units arranged linearly. Grains, vegetables, fruit, nuts, cereal bran. Polysaccharides containing sugars other than glucose. Cereal grains, vegetables, fruit, legumes (for example: peas, beans, chick peas, lentils) and nuts.
Do proteins contain nucleic acids?
Protein is a molecule made up of polypeptides. It is a class of biological molecule consisting of chains of amino acids called polypeptides. Nucleic acid is a class of macromolecules made up of long chain of polynucleotide that includes deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
What are nucleic acids two examples?
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. The other type of nucleic acid, RNA, is mostly involved in protein synthesis.
Is an important component of proteins and nucleic acids?
Nucleic acids also typically contain phosphorous, and nitrogen plays an important structural role in nucleic acids and proteins. The proteins, being made up a diverse set of amino acids, have, in addition to carbon, hydrogen, oxygen, and nitrogen, the elements sulfur and selenium.1 oct. 2020
