Front (Question)

Is lipid hydrophobic or hydrophilic

Back (Answer)

hydrophobic

Front (Question)

What are the 3 major classes?

Back (Answer)

simple lipids, compound lipids, derived lipids

Front (Question)

What are the two categories of simple lipids?

Back (Answer)

fats ( triglycerides, edible fat/oils) and waxes (fatty alcohol esters and jojoba)

Front (Question)

what are the 3 categories of compound lipids?

Back (Answer)

phospholipids (lecithin), glycolipids, lipoproteins

Front (Question)

what are the 3 categories of derived lipids?

Back (Answer)

fatty acids, fatty alcohol, hydrocarbons (oxygenated derivatieves and flour/color compounds)

Front (Question)

what is the definition of simple lipids?

Back (Answer)

esters of fatty acid connecte to an alcohol. The esters of fatty acid are connected to glycerol

Front (Question)

what is the definition of compounds lipids?

Back (Answer)

conjugated to non-lipid moiety

Front (Question)

what is the definition of derived lipids?

Back (Answer)

derived from simple/compound classes

Front (Question)

what is another synonym of simple fat

Back (Answer)

triacylglycerol

#10

Front (Question)

What the term oil refers to? Indice MP

Back (Answer)

refers to fat that have a low melting point and are liquid at room temperature. Fat is solid at room Temp

#11

Front (Question)

The most lipids found are

Back (Answer)

triglycerides

#12

Front (Question)

What is the difference between the melting point of a pure triacylglycerol and a typical edible fat

Back (Answer)

The edible fat melts over a much wider range of temperature because it consists of a mixture of many different pure triacylglycerol molecules, each with different melting points

#13

Front (Question)

What is an wax? Give some examples

Back (Answer)

esters of fatty acids esterified with an alcohol, other than glycerol. EX: jojoba oil, bee’s wax

#14

Front (Question)

What are the applications of food use for waxes?

Back (Answer)

Largely used as sealing agents (cheese) and polishing agents (apple) Also being considered of potential low-calories food ingredient which give a “fatty sensation”but provides FEW CALORIES.

#15

Front (Question)

Apart from food, what other product could wax be used for ?

Back (Answer)

cosmetics

#16

Front (Question)

what are some compounds in the wax category?

Back (Answer)

complex alcohols such as cholesterol, esters of vitamin A or retinol

#17

Front (Question)

True or false Waxes are important because they are biologically active

Back (Answer)

true

#18

Front (Question)

Compound lipids are made up with what

Back (Answer)

They are made up of a sigle lipid (generally the triglyceride type) conjugated to a non lipid molecule

#19

Front (Question)

What are phospholipids made of?

Back (Answer)

Is a triglycerides with one of thei fatty acid replaced with a non lipid moiety - phosphoric acid

#20

Front (Question)

Phosphoric acid is conjugated to what?

Back (Answer)

to some other non-lipid molecule

#21

Front (Question)

What is the basic structure of the non-lipid moiety Indice : has a X

Back (Answer)

phosphatidic acid X=OH X is nitrogenous base

#22

Front (Question)

What is the structure for phosphatic acid

Back (Answer)

X=OH

#23

Front (Question)

what is the structure for phosphatidylethanolamine

Back (Answer)

X=O-CH2-CH2-NH2

#24

Front (Question)

What is the structure for phosphatilchoine

Back (Answer)

X=O-CH2-CH2-N(CH2)3
