Polar (5): Serine, threonine, asparagine, glutamine, cysteine

Negatively Charged/Acidic (2): aspartate, glutamate

Positively charged/Basic (3): lysine, arginine, histidine

Question 2

What are the non-polar, non aromatic AA (7):

Answer 2

Non-Polar, non aromatic (7): Glycine, Alanine, Valine, Leucine, Isoleucine, Methionine, Proline

Mnomic: Val, Alan, and Lucy (& IsoLeucine) smoke Meth with Proline Gloves

Question 3

What are the aromatic proteins (3):

Answer 3

Aromatic (3): Tryptophan, phenylalanine, tyrosine

TP: all start with T or P, that you wipe poop with, that is very aromatic

What is special about it (x3)?

Answer 8

1. Non-polar, non-aromatic
2. Glycine= Gly= G
3. it is

• achiral
• single hydrogen atom for side chain
• smallest amino acid

Question 9

What is the chemical composition of proline?
What category is it in?
What is the three letter code?
What is the one letter abbreviation?
What is special about it (x3)?

Answer 9

1. Non-polar, non-aromatic
2. Proline= Pro= P
3. it is

• structure makes kinks in beta plated sheets
• side chain is covalently bonded to the amino group

Question 10

What is the chemical composition of cysteine?
What category is it in?
What is the three letter code?
What is the one letter abbreviation?
What is special about it (x3)?

Answer 10

1. Polar
2. Cysteine= cys= C
3. it is

• It is important in disulfide bonds, which are covalent bonds between the sulfur residues of the cysteine AA.
• disulfide bonds form by losing the hydrogens and forming the bond.
