What is the L configuration of a sugar in a Fisher projection? - ANSWER hydroxyl on left
What is the difference between glycogen and amylopectin? - ANSWER glycogen- has branches about every 10 residues (more highly branched)
amylopectin- has branches about every 25
What is amylose made up of? - ANSWER glucose
What makes up starch? - ANSWER amylose
amlyopectin
What is a glycosidic bond? - ANSWER links two monosaccharides together at points 1 and 4
What is the difference between an alpha(1-4) and beta(1-4) linkage? - ANSWER alpha: when the oxygen is pointed down in a glycosidic bond
beta: when the oxygen is pointed up in a glycosidic bond
What is the definition of a carbohydrate? - ANSWER all have hydroxyl and carbonyl functional groups
Difference between aldose and ketose - ANSWER aldose has an aldohyde
ketose has a ketone
What makes up sucrose? - ANSWER fructose and glucose monosaccharides
What makes up lactose? - ANSWER glucose and galactose monosaccharides
What makes up mannose? - ANSWER two glucose monosaccharides
What are lipids? - ANSWER soluble in other nonpolar solvents (not water)
What are triglycerides composed of? - ANSWER glycerol and three fatty acids
What is saponification? - ANSWER base hydrolysis of a triglyceride or other fat
strong base is added
breaks ester linkages to release hydroxyls and form glycerol
What has a higher level of unsaturation -- oils or fats? - ANSWER oils
liquid at room temperature
What is the structure of the plasma membrane? - ANSWER hydrophylic head
hydrophobic fatty acid tails
proteins span the phospholipid bilayer
Why type of amino acid is present in the plasma membrane among the fatty acid tails? - ANSWER hydrophobic/nonpolar
What is passive transport (simple diffusion)? - ANSWER no energy required
no protein required
move from high concentration to low concentration
water, gases, ethanol (small nonpolar) can pass through
What is facilitated diffusion? - ANSWER requires protein
no energy required
molecules are two large to go through on their own
What is active transport? - ANSWER energy is required
moves from low to high concentration
