What are the bond linking monomers for each of these biological macromolecules: Protein, Carbohydrate, Nucleic Acid, and Lipid.

Expert Solution

Protein - Peptide bond

Proteins are formed by when the amino acids(Monomers) are linked by a covalent bond known as a peptide bond. In peptide bond carboxyl group of one monomer is linked with the amino group of another monomer and a molecule of water is lost.

Carbohydrate - Glycosidic bond.

In glycosidic bond monosaccharides(monomers) are linked together and a molecule of water is released. OH group of both the monomers are linked together which results in dehydration. It is a type of covalent bond.

Nucleic acid - Phosphodiester bond

In phosphodiester bond nucleotides are linked together. The bond is formed between OH of 3' carbon of one monomer sugar and OH of a phosphate group present 5' carbon of the sugar of another monomer. In the process water is lost. It is also a type of covalent bond

Lipid - Ester linkage.

Like every other linking bonds of biomolecules, it is also a dehydration reaction that means a water molecule is lost and it is also a covalent bond.

What is the polymer for each macromolecule? (carbohydrate, protein, lipid, & nucleic acid)

In studying a particular bio-molecule (a protein, nucleic acid, carbohydrate, or lipid) in the laboratory, the biochemist first needs to separate it from other biomolecules in the sample—that is, to purify it. Specific puri-fication techniques are described later in the book. However, by looking at the monomeric subunits of a biomolecule, you should have some ideas about the characteristics of the mole-cule that would allow you to separate it from other molecules. For example, how would you separate (a) amino...

Arrange these biological molecules (nucleic acid, cellulose, unsaturated fatty acid, saturated fatty acid) in order from highest to lowest energy density? Take note of which chemical bonds have the highest potential energy. Can you explain which bonds have high or low potential energy and why? Also, covalent bonds between which of the atoms will have the highest potential energy?

For a sample containing both protein and nucleic acid, the absorbance measured at a particular wavelength will be the sum of contributions from both types of molecule. Using the protein and nucleic acid concentrations you calculated in the previous step, calculate how much of the absorbance of the BSA and E.coli extract comes from protein and how much from nucleic acid, at each wavelength. HINT: the values in the table provided, are in essence, extinction coefficients with the units (mg/ml)-1cm-1....

Sort the parts of a nucleic acid according to whether each occurs exclusively in DNA, exclusively in RNA, or in both types of nucleic acid.
