Monomers of Proteins An amino acid is a subunit of protein a polymer found throughout nature. An amino acid is therefore the monomer of protein.
Cellulose another natural polymer is the main structural component of plants.
Is amino acid a polymer. A polymer may contain hundreds of thousands of monomer units. The physical and chemical properties of a large polymer is always very different from its constituent monomers. A protein is a polymer of amino acids.
There are 20 different amino acids that are combined in chains by the protein-building machinery of the cell. If the monomer is an amino acid the polymer will be a long chain of individual amino acids. An amino acid chain forms a protein.
A string of amino acids is called a polypeptide chain. Polypeptide chains grow in number and begin to fold creating helices and plated sheets. These interact with one another and keep becoming more and more complex until a protein is formed.
Chains of about 50 amino acids or more are usually called proteins or polypeptides. A sequence of amino acids in a peptide or protein is written with the N-terminal amino acid first and the C-terminal amino acid at the end writing left to right. The polymers are formed from a single amino acid that is the repeat unit of the polymer formed and are commonly termed polypeptides homopolypeptides and polyamino acids.
In this chapter the term polyamino acids will be used to describe such polymers as this title reflects that the polymer formed consists of amino acid repeat units and avoids confusion with peptides that are composed of multiple amino acids. Monomers of Proteins An amino acid is a subunit of protein a polymer found throughout nature. An amino acid is therefore the monomer of protein.
A basic amino acid is made from a glucose molecule with an amine group NH3 a carboxyl group COOH and an R-group side chain. Also is cellulose a polymer of amino acids. Polymers are widely found in nature.
The human body contains many natural polymers such as proteins and nucleic acids. Cellulose another natural polymer is the main structural component of plants. It is also referred to as a polysaccharide because it is a polymer of the monosaccharide glucose.

An amino acid is therefore the monomer of protein. A basic amino acid is made from a glucose molecule with an amine group NH3 a. A polyamino acid is a polymer composed of amino acids as monomeric units.
Structural and functional proteins polypeptides peptides. As we noted for nucleic acids a polymer is a chain of subunits amino acid monomers linked together by peptide bonds. Under the conditions that exist inside the cell this is a thermodynamically unfavorable dehydration reaction and so must be coupled to a thermodynamically favorable reaction.
A molecule formed from two amino acids joined together by a peptide bond is known as a dipeptide. Question 1-A nucleotide and or amino acid are not polymer as An amino acid is a subunit of protein amino acid is therefore the monomer of protein. Nucleotide is monomer nucleic acid polym view the full answer.
Previous question Next question. Polypeptides and proteins are polymers of amino acids and some major examples include collagen actin and fibrin. Polysaccharides are linear or branched polymeric carbohydrates and examples include starch cellulose and alginate.
