Protein
Classification of amino acid
Aliphatic amino acid
Hydrophobic
Unreactive
R-group contain hydrogen & carbon
Example
Glycine
Alanine
Valine
Leucine
Isoleucine
Amino acid & amide
Amide
Uncharged
Cannot be ionised
Example
Glutamate
Glutamine
Amide of glutamate
Aspartate
Asparagine
Amide of aspartate
Aromatic amino acid
Absorb UV light
R-group have benzene-like ring
Example
Phenylalaline
Tyrosine
Tryptohan
Basic amino acid
Highly hydrophobic
Polar
Positively charged
Arginine & lysine both pKa=10
histidine can interconvert between negatively and positively charged depends on pH
Example
Lysine
Arginine
Histidine
Cyclic amino acid
Non polar
Not reactive
Imono acid
Example
Proline
R-group bonded with nitrogen as well as
alpha carbon
Hydroxyl & sulfur containing amino aid
Hydroxyl group
Example
Serine
Threonine
Weakly polar
Sulfur contain amino acid
Methionine more reactive than cysteine
Fairly non-polar
Hierarchy
Primary structure
Linear structure
Quarternary structure
Made from diff. types polypeptide
Secondary structure
Hydrogen bonding
Alpha helix Beta pleated sheet
Tertiary structure
Forming 3D shape
Group of Alpha helix & Beta pleated sheet fold further & cross link
Force to stabilize
Disulfied bridge
Hydrogen bond
Salt bridge
Description

Oligopeptide
Polypeptide
Tripeptide
Type of protein
Globular
Folded
Contain Grooves
Compact
Soluble in water
Example
