Question 4

explain how glucose molecules can combine to form disaccharides and polysaccharides

Answer 4

condensation reaction - the linking of a monosaccharide to another monosaccharide, disaccharide, or polysaccharide by the removal of a water molecule

Question 5

saturated fats

Answer 5

no double bonds between the individual carbon atoms of the fatty acid chain. Saturated fats originate from animal sources, for example, meat, poultry, full-fat dairy products

Question 6

unsaturated fats

Answer 6

one or more double bonds between carbon atoms within the fatty acid chain. originate from plant based foods like avocados and peanuts

Question 7

non-essential amino acids

Answer 8

can be synthesized by body

Question 9

lipid - 4000 kj
protein - 1720 kj

Question 11

diet between endurance and non-endurance

Answer 11

endurance must have higher amounts of carbs, and protein an fat intake is slightly higher

Question 13

which dietary fat is most prevalent

Answer 13

triglycerides (95%), one molecules of glycerol and three molecules of fatty acids

Question 14

glycerol and triglycerides

Answer 14

combine through condensation reaction, glycerol and 3 fatty acids to make triglycerides

Question 15

different fatty acids

Answer 15

saturated, unsaturated, and polyunsaturated

Question 16

saturated

Answer 16

max amount of hydrogen, four on each carbon, no double bonds

Question 17

unsaturated

Answer 17

hydrogen atoms are missing, there are double bonds between carbons to make it unsaturated

Question 18

monosaturated

Answer 18

A single double bond in the carbon chain.

Question 19

polyunsaturated

Answer 19

Multiple double bonds between carbons

Question 20

omega 3

Answer 20

The first double bond is located between on third carbon atom on the methyl end, fish and flaxseed

Question 21

omega 6

Answer 21

The first double bond is on the 6th carbon from the methyl end, veggie oils/nuts/seeds

Question 22

hydrogenated fats

Answer 22

Hydrogenation is a process in which a liquid unsaturated fat is turned into a solid fat by adding hydrogen, making it into a trans fat

Question 23

Answer 23

second most abundant

Question 24

amino acids

Answer 24

amino acids are organic (carbon based) compounds that combine to form proteins.

Question 25
