AMINO ACIDS
- 5 structural features
- Amino group (-NH2)
- Carboxyl group (-COOH)
- Central carbon atom (alpha carbon)
- Hydrogen atom (-H)
- Side chain, or known as 'R' groups
- Amino group (-NH2)
- 20 amino acids
- Nonpolar (Hydrophobic) amino acids
- Alkyl side chains
- Aromatic side chains
- Alkyl side chains
- Polar (Hydrophilic) amino acids
- Neutral side chains
- Acidic side chains
- Basic side chains
- Neutral side chains
- Nonpolar (Hydrophobic) amino acids
- PEPTIDE BONDS
- Peptide bonds are the covalent
carbon-to-nitrogen bond that links one
amino acid with another amino acid in
peptides and proteins, releasing a molecule
of water. This is called Condensation
reaction.
- This is the reverse of the condensation reaction
which is Hydrolysis reaction.
- This is the reverse of the condensation reaction

- Oligopeptide (2-10) amino acids
- Polypeptide (more than 10 amino acids)
- Polypeptide (more than 10 amino acids)
- Flat (planar) structure
- Function
- The building blocks of
proteins
- Form parts of coenzymes
- As precurcors for the biosynthesis
of molecules
- Some amino acids can acts as
chemical messengers
- Non-essential amino acids
- Amino acids that
our body can make
- Amino acids that
our body can make
- Essential amino acids
- Amino acids that our body
can't make, so we can get them
through our diet e.g fish and
meat
- Amino acids that our body
can't make, so we can get them
through our diet e.g fish and
meat
- Conditionally Non-essential
- May needed more in times of
growth, sick, pregnancy
- May needed more in times of
growth, sick, pregnancy
- The building blocks of
proteins
