how do you determine whether a monosaccharide is alpha or beta?
you look at the free anomeric carbon
would an 18 carbon fatty acid be soluble in water?
no, it has too many carbons
What is the triacylglycerol reaction that only works on unsaturated fatty acids and adds H2
hydrogenation
Where is glycogen found?
In the liver and muscles
Fats, Oils, and Waxes are examples of what?
lipids or fatty acids
what two functional groups are needed to form a peptide bond?
a carboxylic acid and an amine
what is the purpose of glycogen in animal cells?
stores energy
what two products do you get during the hydrolysis of a fat
a glycerol and 3 fatty acids
what example was used to describe the structure of an alpha helix protein?
a cork screw
Which is the C-terminal in the following poly peptide:
Gly-Gly-Lys-Ser-Ala
Ala (the last amino acid)
Which monosaccharides make up lactose?
glucose and galactose
Which two characteristics belong to INorganic compounds:
has covalent bonds
ionic bonding
low melting point/boiling point
low flammability
flammable
insoluable
ionic bonding & low flammability
what two reactants do you need during the esterification of a fat?
a glycerol and 3 fatty acids
what are the three secondary structures of proteins?
alpha helix, beta pleated sheet, triple helix
What is the name of the saturated fatty acid with an 18 carbon chain that comes from animal fat?
Stearic Acid
Determine which one is saturated and unsaturated?
Oleic and Stearic Acid
Oleic = unsaturated
Stearic = saturated
Which of these is WRONG about unsaturated fatty acids:
low melting/boiling point
solid at room temperature
can't stack close together
less LDFs
solid at room temperature
- they're liquid
amidation is used in the process of making what?
carbohydrates
polypeptides
lipids
polypeptides
how are the glycosidic bonds of cellulose and amylose different?
cellulose has a bond of beta 1,4 while amylose is alpha 1,4
what is the name of the process that adds triacylglycerol to 3NaOH?
saponification
What are "essential" amino acids?
amino acids that can't be manufactured in humans
Why do saturated fatty acids have a higher melting and boiling point than unsaturated fatty acids?
Since they don't have any double bonds, they are able to stack on top of each other and create more London dispersion forces
What is the name of the reaction that produces C6H12O6 and oxygen?
photosynthesis
which amino acids are hydrophobic?
polar, acidic, basic
What is the name of the reaction that turns a fat from liquid to solid?
hydrogenation (unsaturated fatty acid to saturated)
