EXAM QUESTIONS AND ANSWERS
2026 COMPLETE EXAM PREP WITH
VERIFIED SOLUTIONS
◉ carboxyl group.
Answer: A -COOH group, found in organic acids.
◉ R group.
Answer: a functional group that defines a particular amino acid that
makes it a specific protein (20 amino acids) aka side chain
◉ alpha carbon.
Answer: the central carbon atom of each amino acid
◉ amino acid backbone.
Answer: The structure comprised of the amino group, carboxyl group
with a central alpha carbon atom.
◉ Hydrophobic.
Answer: non polar, afraid of water
◉ polar.
Answer: Amino acid Molecule with partial charges. Mixes with water.
, ◉ charged.
Answer: Amino acid has a positive or negative charge
◉ Polypeptide.
Answer: A single protein chain formed by amino acids bonded together
◉ peptide bond.
Answer: The chemical bond that forms between the carboxyl group of
one amino acid and the amino group of another amino acid by
dehydration ( In which a water molecule is removed, C-N bond)
◉ Hydrolysis.
Answer: Peptide bonds can be broken by this...A chemical process that
splits a molecule by adding water. ( this happened frequently in the
stomach when proteins begin to bee digested into their amino acids)
◉ Residue.
Answer: Remaining portion of amino acids after linked by peptide bonds
( how R groups get their name)
◉ N-terminus.
Answer: the end of a polypeptide or protein that has a free amino group (
usually on the left)
