◉ Example of proteins used for structural purposes. Answer: Keratin in
hair, collagen in skin
◉ What is a catalyse. Answer: Something that speeds up metabolic
processes and does not harm itself in the process
◉ One example of protein catalyse. Answer: Protease. Breaks down
proteins in cells to help reduce unneeded proteins
◉ What class of proteins help aid in immunology. Answer: Antibodies
◉ Example of a transport protein. Answer: Hgb
◉ Example of a storage protein. Answer: myoglobin
◉ Example of a protein hormone. Answer: relaxin, relaxes pelvic
ligaments during childbirth
◉ Characteristics of an "alpha" carbon. Answer: Carbon adjacent to a
carboxylic acid
, ◉ What parts do all amino acids have in common. Answer: Amino
group, carboxylic acid, and alpha carbon
◉ 5 categories of amino acids. Answer: Non polar: Aliphatic and
aromatic
Polar: Neutral, acidic, basic
◉ Are aliphatic acids large or small? Hydrophobic or philic?. Answer:
Small and hydrophobic
◉ What is special about proline?. Answer: Sidechain forms bond with
amine group forming a rigid, planar structure
◉ Do aliphatic amino acids have any double bonds in their structures?.
Answer: No, only single
◉ How do aromatic amino acid structures relate to light?. Answer:
Alternating single/double bond rings called a conjugated system absorb
light efficiently
◉ How much light can an aromatic amino acid absorb?. Answer: UV
light at 280 nanometers
