Biology 1A Week 2 Macromolecules

Polysaccharides, lipids, proteins, AT,CG

Triglycerides are commonly known as

oils and fats

Saturated has more hydrogens

Then unsaturated.

Glucose is the monomer for which polysaccharide….

Glycogen and cellulose

Glycosidic linkage joins glucose monomer in

polysaccharides

5’GAT3’ also written same as.…

3’TAG5’ (same strand of DNA)

5’TTG3’ is the same as

3’GTT5’

5’ACG3’ is a single strand which is linked with

5’CGT3’

If a protein is denatured, that means

No longer holds a 3D shape

Anfinsen used urea and beta-mercaptoethanol, Do these break peptide bonds

No, bonds stay intact

Urea breaks H-bonds, beta-mercaptoethanol breaks disulfide bonds. Which level of structure do these chemicals affect?

Secondary and tertiary structures

Anfinsen’s steps of experiment:

Add urea and beta-mercaptoethanol to denature the protein

Measure enzyme activity of the protein found no activity

Remove urea and beta-mercaptoethanol from protein solution then wait

Measure enzyme activity of the protein’s activity restored

When the enzyme is treated with urea and beta-mercaptoethanol , x3

No hydrogen bonds

No enzyme function

No disulfide bonds

No 3D shape (structure)
