Classify the following amino acid acidic basic neutral Classify the following amino acid. acidic basic neutral Which amino acid has two carbonyls? Glutamine Isoleucine Tyrosine Lysine Amino Acid Charge What is the charge on alanine at pH = 6.01 ? -2 -I o +I what is the charge on isoleucine at pH = 2? +2 +l o -I Is the following amino acid R or S? R S Peptide Bonds Amide nitrogens are classified as basic it depends on the solution the amino acid is in it depends on the amino acid non-basic Protein Structure What level of protein interaction is described by p-pleated sheets? primary secondary tertiary quaternary Which of the following is an example of an unsaturated fatty acid? Arachidic Laurie Linolenic Myrisitc Fats What fat has 12 carbons and is fully saturated? Laurie acid Palmitic acid Oleic acid Stearic acid What fat has 18 carbons and is fully saturated? Stearic acid Arachidic acid Palmitic acid Myristic acid Fats Which of

Explanation / Answer

Answers are:

1) B Basic

2) C (Amides are considered as neutral)

3) A Glutamine

4) C (Since pH is neutral, charge also be neutral)

5) B (In Acidic solution H+ will be added to the isoleucine which will be available in acidic medium)

6) A (R configuration)

7) D (Non-basic)

8) B (Secondary)

9) A, B, C are unsaturated and D is saturated

10) A (Lauric acid, C12H24O2)

11) A (Stearic acid, C18H36O2)

12) C (Butter, 28-45%)
