Question 1

examples of polysaccharides

Answer 1

alpha and beta glucose

Question 2

how are steroids formed, hint (form follows function)

Answer 2

*** STEROIDS ARE FORMED BASED ON THE R-GROUP/FUNCTIONAL GROUP ADDED TO A HYDROCARBON CHAIN

Question 3

how do you know if a hydrocarbon chain is saturated or unsaturated?

Answer 3

UNSAT- AT LEAST ONE C=C
SAT- ALL C-C

Question 4

formal definition of dehydration synthesis

Answer 4

where the fatty acids react with the alcohol groups (OH-) on the glycerol molecule to form an ester bond with the release of water.

Question 5

which of the monosaccharides are aldose and which are ketose?

Answer 5

glucose and galactose= aldose (g.a)
fructose=ketose (f.k)

Question 6

shape of fructose?

shape of glucose?

Answer 6

FRUCTOSE- PENTAGON
(PF)
GLUCOSE- HEXAGON
(GH)

Question 7

steroids come in which form?

Answer 7

carbon fused rings

Question 8

will optical isomers have the same chemical properties/function

Answer 8

no, form follows function, so with the mirrored arrangement of the isomer, the function will also follow suit in being different

(example of this includes alpha and beta glucose, alpha= energy storage, beta= structural components)

Question 9

why do we need fat

Answer 9

fat is important:

• helps with intaking and dissolving fat-soluble vitamins
• insulation
• energy storage
• cell cushioning
• increased brown fat increases temperature in blood
• important for organs

(APPLIES FOR HEALTHY FATS!!)

Question 10

how do the properties of water benefit freshwater fish during the winter?

Answer 10

• hydrogen bonds become more rigid when the water freezes, making ice less dense than water, letting it float overtop as a “insulation layer”
• water has great energy and heat attachment properties, so it can have an adequate temperature for the fish to survive in the wintertime

Question 11

Why do you need water for the breakdown of carbs and protein

Answer 11

hydrolysis requires water because you’re reversing the process of dehydration synthesis, where a water molecule is formed from the formation of a disaccharide

now, when we want to break that disaccharide, we want that water to be present during the breakage

Question 12

what are the five forms of lipids

Answer 12

5 FORMS OF LIPIDS: fats, oils, waxes, phospholipids, and steroids
