condensation of fatty acids and alcohol to form ester

saturated and unsaturated

31

A

ester

32
Q

triglycerides

A

three esters

33
Q

phospholipids

A

two esters and two phosphoesters

34
Q

ester functional group result from

A

condensation of carboxylic acid and alcohol

35
Q

acid hydrolysis of triglyceride

basic hydrolysis of triglyceride

A

acid- glycerol and fatty acid

basic- hydrolysis and salt of fatty acids (soap)

36
Q

micelle

A

encapsulate grease with their nonpolar ends and face the outside water environment with their polar ends.
soap molecules

the structure is called micelle

37
Q

storage of triglyceride

A

triglycerides with saturated fatty acidy, solid at room temperature
triglycerides with unsaturated, oil at room temperature
stored in our adipose tissue

38
Q

Glycerol reaction with a fatty acid yields?

A

lipid

39
Q

a lipid triglyceride is formed by a reaction of

A

fatty acid and glycerol

40
Q

fatty acids are stored in adipose tissue as

A

triglycerides

41
Q

a micelle is likely formed from

A

fatty acids

42
Q

Steroids

A
  • compounds containing the steroid nucleus which is 3 cyclohexane and 1 cyclopentane
  • Cholesterol is the most abundant steroid in the body
  • Steroid hormones are derivatives of cholesterol (sex hormones, testosterone, estrogen, and progesterone)
43
Q

Terpenes

A
  • made of repeating isoprene unite (2-methyl, 1-3-butene)
  • steroids are derivatives of the triterpene squalene
    example= vitamin A
44
Q

How to develop nucleic acid?

A

condensation/hydrolysis

1) sugar and base is condensed to form a nucleoside (key bond formed is N-glycosidic bond)
sugar+base=nucleoside + water
2) nucleoside and phosphate group condense and form a nucleotide (key bond formed is phosphoester)
nucleoside+ phosphate= nucleotide + water
3) condense 3-OH- group of the sugar in one nucleotide to the phosphate group on the 5’carbon atom of the next nucleotide
nucleotide+nucleotide= dinucleotide+ water

45
Q

double helix formed

A

A-T- two hydorgens

G-C three hydrogens

46
Q

mRNA

A

3 base codon
