quiz three Flashcards
monosaccharide
the simplest form of carbohydrate, composed of 3-7 carbon atoms serves as fuel for organisms.
examples of monosaccharides
ribose and glucose
disaccharides
a sugar composed of 2 monomeric units linked by means of covalent bonds
examples of disaccharides
sucrose, maltose and lactose
polysaccharides
complex carbon hydrate built from simple carbohydrates, linked through dehydration synthesis.
examples of polysaccharides
starch, glycogen, and cellulose
glucose
a monosaccharide, 6 carbon sugar (hexose) serves as an important source of c3ellular fuel (C6H12O6)
why did we do the biuret test
to detect protein
why did we do the benedict test
identify reducing sugars
why did we do the iodine test
distinguished starch from other carbs
why did we do the grease-spot test
identify the limpid nature of a substance
what is the building blocks of protein
amino acid
saturated fatty acids
all carbon atoms are linked together by one single bond but contain the maximum number of hydrogen atoms
unsaturated fatty acids
do not have the max number of hydrogen atoms, have one or more double bonds between the carbon atoms
hypertonic
solution is a lower concentration than inside the cell, water will be drawn out of the cell
hypotonic
solution is a higher concentration of solvent that inside the cell, will shrink
Isotonic
same concentration within the solvent and the inside of the cell
the difference you observed in between the algae leaves with different solvents
hypertonic (NaCl)= cell shrinks
hypotonic = cell swelled
control (tap water)=Isotonic cells seem nice
what is an essential amino acid?
they are vital for specific functions. such as protein synthesis, tissue repair, and nutrient absorption.
examples of essential amino acids?
Histidine, Isoleucine, Leucine, Lysine, Methionine
peptide bond?
this is a covalent bond that forms between an amino group and a carboxyl group of another amino acid
saturated fat is
wehen saturatted fatty acids with max number o hydrogen atoms are bonded with single bonds
saturated fat example
butter and lard
unsaturated fat is
composed of unsaturated fatty acids, that are have one or more double bonds between carbon atoms
