determines the type of amino acid out of the 20 possible ones
a condensation reaction between two amino acids
condensation between 2 amino acids
condensation between many amino acids
a sequence of amino acids bonded by peptide bonds as a result of condensation reaction
the number and order of amino acids affects other structures
coiling or folding of amino acid chain to result in an alpha helix or a beta pleated sheat
between the NH2 group and carboxyl groups
combination of pleated sheets and helixes, now a polypeptide which is 3D in shape
hydrogen, ionic, and disulfide bonds
hydrophilic and phobic interactions to face R group inwards
they are hydrophobic
denatured by heat as kinetic energy loosens the shape and returns to the primary structure
consists of more than 1 polypeptide chain (multiple tertiary)
haemoglobin
weak negatively charged nitrogen and weak positively charged hydrogen attract to eachother forming hydrogen bonds
protein folds so that 2 parts of the polypeptide chain are parallel to eachother encouraging hydrogen bonds to occur between parallel peptide bonds
hydrogen bonds form every fourth peptide bonds
interactions between sulfur in R groups
from between carboxyl and and amino groups that are not involved in a peptide bond
numerous between many hydrogens, easily broken
