lipids bro

Question 1

define lipid

Question 2

wassa triglyceride

Answer 2

its a typa lipid its composed on one glycerol (achohol) and three carboxyllic acid groups (fatty acids) which r joined thru a condensation reaction which creates an ester bond.

an ester formed from glycerol and three fatty acid groups. Triglycerides are the main constituents of natural fats and oils.
its a typa fat found in ur blood

Question 3

where r triglycerides mostly found

Answer 3

in adipose tissue (usually) , made up of differentiated cells called adipocytes

or energy and thermal insulation

Question 4

what are the types of lipids

Answer 4

triglycerides
phospholipids
steroids
waxes

Question 5

wassa phospholipid

Answer 5

Phospholipids are another important type of lipid that also form by condensation. A phospholipid consists of a glycerol molecule modified with a phosphate group and two fatty acids

Question 6

what are triglycerides used as

Answer 6

thermal insulators to body temperature and habitat.

Question 7

what are satruated fats

Answer 7

these fats do not have any carbon - carbon double bonds. thus they r usually linear and r usually solid at room temp

Question 8

wassa unsaturated fatty acid and what r the types

Answer 8

these have one or more than one carbon - carbon double bonds in the hydrocarbon chain which is what makes it non-polar and hydrophobic
monounsaturated - only on carbon - carbon double bond
polyunsaturation - more than one carbon - carbon double bond

Question 9

what can fatty acids be classified as

Answer 9

saturated, unsaturated
unsaturated = less hydrogens attached to one carbon which is one thing that makes them liquid at room temp, their bends or kinks also allow for that

Question 10

wassa hydrocarbon chain

Answer 10

Hydrocarbon chains are long, linear chains of carbon and hydrogen atoms that make up the backbone of fatty acid molecules

Question 11

what r the types of mono and poly unsaturated fatty a’s

Answer 11

cis and trans fats

Question 12

what’s a cis fat

Answer 12

made naturally, hydogen atoms r on same side of double bond. - typa unsaturated fat
less bends n kinks = more linear, higher melting point in comparison to trans fats.

Question 13

wassa trans fat

Answer 13

not naturally, typa unsaturated fat - industrially so then their hydrogen atoms r at opposing sides of the double bond. creates more bends and kinks in the hc chain, causes it to have a lower melting point in comparison to cis facts.

Question 14

gimme an example of triglycerides being used as thermal insulators in animals

Answer 14

its the blubbwhaer found in whales
cuz its hydrophobic and its a lipid its more energy dense, and also allows for energy and thermal insulation
its found in the adipose tissue (adipocytes r the name of the cells btw) of the blubber in whales.

Question 15

what does It mean when something has both phobic and phillic properties

Answer 15

amphipathic - its a phospholipid

Question 16

what r phospholipids comprised of

Answer 16

neg charged phosphate head and glycerol grp (its the CH2 Ch3 shit u needa learn how to draw that)
then it has two hydrocarbon tails at the end which make it phonic
these hc tails can be saturated or unsaturated

Question 17

what happens when two phospholipids combine cuz of their phillicphobic properties

Answer 17

so their heads attract the extracellular fluid and the tails r in the middle so this creates a bilayer which is what a plasma membrane is made of

Question 18

what r steroids

Answer 18

Steroids are a group of naturally occurring hormones that play a vital role in regulating a wide range of physiological functions in the body.

Question 19

example of 3 steroid

Answer 19

cholesterol are an important component of the phospholipid bilayer providing it with both stability and flexibility (see subtopic B2.1). Other steroids play an important role in signalling.
- oestradol - female reproductive
- testosterone - male repro
