Q

What is true about Allosteric Regulation?

A

It can include BOTH activation and inhibition

An allosteric ligand binds to a site on enzyme that is NOT the active site!

Q

What does Chiral mean?

A

It means that the Alpha carbon has got 4 DIFFERENT constituents (groups attached!)

17
Q

Aliphatic means…

A

Contains chains of Carbon and Hydrogen

18
Q

Glycine is the ONLY… amino acid

A

Non - chiral!

19
Q

What is meant by non-polar?

A

Hydrophobic
CAN’T form hydrogen bonds
Therefore NOT soluble in water!

20
Q

Peptide bonds: which characteristic provides restriction to the rotation that can happen around the bond?

A

They are a form of Covalent bond and have a partial 2+ charge meaning that there is just enough Pi bonding between the Carbon and Nitrogen to restrict movement around the bond!
