What are carbohydrates broken down into? - answer✔simple sugars/glucose
What are the groupings of simple sugars? - answer✔1. monosaccharide: 1 monomer of sugar
-glucose, fructose, and sucrose
2. disaccharide: 2 monomers of sugar
What type of bonds do lipids have? Are they hydrophobic or hydrophilic? - answer✔1. C-H
2. hydrophobic b/c of fatty acid tails
What are 3 types of lipids? - answer✔1. phospholipids
2. steroids
3. waxes
Describe triglycerides, phospholipids, steroids, and waxes - answer✔1. triglycerides: contains a glycerol
head + 3 fatty acids
2. phospholipids: contains a phosphate head + 2 fatty acids
-aids in cell structure and membrane
3. steroids: are derived from cholesterol, which is found in the cell membrane and throughout the blood
4. waxes: a long chain alcohol binds to a long chain fatty acid
What are polypeptides? Why does it occur? - answer✔1. a linkage of multiple (10-100) peptides; an
amino acid chain
2. is a result of condensation reactions
Differentiate between condensation reactions and hydrolysis. - answer✔1. condensation reactions:
removal/loss of water when 2 molecules are joined together
2. hydrolysis: addition of water; water is broken down into H+ cations and OH- anions
What is a peptide? - answer✔a compound of 2 or more amino acids
What makes up an amino acid? - answer✔1. amino group (NH2)
2. carboxyl group (COOH)
3. R group (determines properties of protein)
4. hydrogen
5. carbon
Describe the 4 protein structures - answer✔1. primary: a sequence of amino acids
