Guide 2025!!!
amino group - ANSWER ✨✔---Consists of hydorgen and nitrogen atoms (-NH3+)
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)
C-terminus - ANSWER ✨✔---the end of a polypeptide or protein that has a free carboxyl group (
usually on the right)
primary structure - ANSWER ✨✔---sequence of amino acids in a polypeptide aka amino acid chain
secondary structure - ANSWER ✨✔---Shape formed by hydrogen bonding of amino acid back bone-
usually an alpha helix or beta sheet
