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.

Are proteins and nucleic acids polymers?
Carbohydrates, nucleic acids, and proteins are often found as long polymers in nature. Because of their polymeric nature and their large (sometimes huge!) size, they are classified as macromolecules, big (macro-) molecules made through the joining of smaller subunits.

Are proteins 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 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.
Are proteins polysaccharides?
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 are the 4 types of polymers?
Terms. Synthetic polymers are human-made polymers. From the utility point of view, they can be classified into four main categories: thermoplastics, thermosets, elastomers, and synthetic fibers.
What are the 4 natural polymers?
Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.
Are proteins a polymer?
Proteins are polymers in which the 20 natural amino acids are linked by amide bonds.22 mai 2020
How do proteins depend on nucleic acids?
The sequence of the codons in nucleic acids determines the sequence of amino acids in a protein. Each codon is composed of three nucleotides (nitrogen bases), and codes for a particular amino acid (or stop codon). The sequence of amino acids determines the structure of a protein, which determines its function.5 mai 2015
Do nucleic acids use proteins for energy?
Nucleic acids are a type of macromolecules that make up the genetic material. This is their main function. Unlike the other three macromolecules (carbohydrates, lipids, and proteins), nucleic acids are not used for energy production; therefore, the results stated in this question don’t seem valid.
What consist of nucleic acids and proteins?
Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
What foods are high in nucleic acids?
Not only did cultivated plants such as cereals and pulses show a high RNA-equivalent content but also vegetables such as spinach, leek, broccoli, Chinese cabbage and cauliflower.
How are nucleic acids used in medicine?
Nucleic acid therapeutics, based on nucleic acids or closely related chemical compounds, are an emerging new class of therapeutics for treating unmet medical needs. They are capable of targeting a disease at the genetic level by preventing the expression of disease-causing proteins.
What are the 3 main functions of nucleic acids?
Nucleic acids function to create, encode, and store biological information in cells, and serve to transmit and express that information inside and outside the nucleus.
