MADMAN BIOLOGY Amino acids are the monomers of proteins. They have a positively-charged amino group on one side and a negatively charged carboxyl group on the other. Attached to the central carbon is a variable group called the 'R' group. This group is different for each amino acid.

Chapter 05 - The Structure and Function of Macromolecules 3. What is a polymer? What is a monomer? A polymer is a long chain-like molecule, consisting of many similar or identical building blocks linked by covalent bonds. A monomer is a smaller molecule that serves as the building blocks of polymers. 4. Monomers are connected in what type of reaction? What occurs in this reaction?

Oligomer Dimers, trimers, and tetramers are, for instance, oligomers composed of two, three and four monomers, respectively. In the context of biochemistry, an oligomer usually refers to a macromolecular complex formed by non-covalent bonding of a few macromolecules like proteins or nucleic acids.

Principles of Biochemistry/Biomolecules A monomer (/ˈmɒnəmər/ MON-ə-mər) (mono- , one + -mer, part) is a molecule that may bind chemically to other molecules to form a polymer. The term monomeric protein may also be used to describe one of the proteins making up a multiprotein complex.ucleotides, monomers found in the cell nucleus, polymerize to form nucleic acids – DNA and RNA. Glucose monomers can polymerize to form starches, glycogen or cellulose; xylose monomers can polymerise to form xylan.

If the monomer is amino acid, the polymer is ? But there are plenty of examples of non-biological (i.e. non-polypeptide) polymers made from amino acid monomers. Sodium poly(aspartate) is an important example of a non-polypeptide polyamide. So the answer is polyamides. Polypeptides are a specific type of polyamide and proteins are a specific type of polypeptide.

Protein structure Interactive diagram of protein structure, using PCNA as an example. Protein structure is the three-dimensional arrangement of atoms in a protein molecule. Proteins are polymers — specifically polypeptides — formed from sequences of amino acids, the monomers of the polymer. A single amino acid monomer may also be called a residue indicating a repeating unit of a polymer.

Principles of Biochemistry/Biomolecules Amino acids are natural monomers that polymerize at ribosomes to form proteins. Nucleotides, monomers found in the cell nucleus, polymerize to form nucleic acids – DNA and RNA. Glucose monomers can polymerize to form starches, glycogen or cellulose; xylose monomers can polymerise to form xylan.

- The monomers in proteins are amino acids, those in polysaccharides are sugar derivatives, (example: hexoses such as glucose or fructose, or pentoses such as ribose). Those in nucleic acids are nucleotides. Lipids as major food components are not organized as proteins, i.e., in a repeating manner of monomers.Proteins, carbohydrates, and lipids constitute the main substrates for digestive enzymes as well as the oral enzymes supplied as dietary supplements.ost food components are macromolecules. Food macromolecules are biological polymers (i.e., chains of repeating units of smaller molecules linked together) and are comprised of proteins, nucleic acids, carbohydrates (polysaccharides), and lipids.

Protein Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific three-dimensional structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides, or sometimes oligopeptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residues in a protein is defined by the sequence of a gene, which is encoded in the genetic code.

- Proteins are linear polymers formed by linking the a-carboxyl group of one amino acid to the a-amino group of another amino acid. This type of linkage is called a peptide bond or an amide bond. The formation of a dipeptide from two amino acids is accompanied by the loss of a water molecule.

- Proteins are composed of α-amino acids linked together by peptide bonds into polypeptide chains. An amino acid is characterized by an amino group (-NH2) and a carboxylic acid group (-COOH) linked to a carbon, known as the α-carbon.Also attached to the α-carbon is a H and various R-groups or side-chains.uilding a polypeptide: Polymers are chains of subunits, monomers, linked together by chemical bonds. The bond between two amino acids is known as a peptide bond. Two amino acids, joined together by a peptide bond, are known as a dipeptide. An amino acid polymer is known as a polypeptide.

What is the difference between a protein and peptide? A protein is a type of peptide. A single peptide is simply a functional monomer that can be grouped into higher level structure to make either an amino acid or protein. So, we have a monomer peptide, which groups with other peptides to make a polypeptide, which can be considered an amino acid (primary structure of a protein). Then, the amino acid, also known as a polypeptide chain, arranges itself into secondary, tertiary, or quaternary to serve a specific function as a protein. I know, confusing. But, like you said, they are basically all the same thing. Just different arrangements.

MACROMOLECULES Although R-groups of some amino acids contain amino and carboxyl groups, branched polypeptides or proteins do not occur. The sequence of monomer units in a macromolecule is called the PRIMARY STRUCTURE of that macromolecule.Each specific macromolecule has a unique primary structure.e will conclude this section of the course with a consideration of denaturation and renaturation -- the forces involved in loss of a macromolecule's native structure (that is, its normal 3-dimensional structure), and how that structure, once lost, can be regained.

Protein and Polypeptide Structure The primary structure of a polypeptide of protein determines its secondary, tertiary, and quaternary structures. Primary Structure. The primary structure of polypeptides and proteins is the sequence of amino acids in the polypeptide chain with reference to the locations of any disulfide bonds.uaternary Structure. Quaternary structure is used to describe proteins composed of multiple subunits (multiple polypeptide molecules, each called a 'monomer'). Most proteins with a molecular weight greater than 50,000 consist of two or more noncovalently-linked monomers.
