FLE 4 Flashcards
An epimer is a what? What’s an anomeric carbon?
an epimer is one of a pair of diastereomers. an anomeric carbon is the carbon in a sugar that when linear is at the top 1 and is either a ketone or aldehyde. often in the cyclic form, it is on the front right corner. Beta form in cyclic is when the hydroxl is UP! alpha is down.
what are the amino acids with aromatic side chains? and their polarities?
Histidine (+ polar), tyrosine (nonpolar), phenylalanine (nonpolar), tryptophan (nonpolar)
explain capacitance to me
capacitance is the measure of how much charge a capacitor can hold (capacitors separate charges to create a difference in positive and negative charged strips of metal separated by paper). the equation is capacitance is equal to how much charge is stored per volt. [C (farad) = Q (coloumbs for charge)/ V (voltage) ]
what kind of amino acids form disulfide bonds and what level of structure do these help?
cysteine (C) and likely tertiary protein structure
what happens when the diaphragm muscles contract? to the lung volume and pressure and what shape does it take?
the muscles go from concave up to flat and the pressure decreases so lungs inflate with air
rate order linear plots of time vs. concentration?
zero order: [conc]= -time // first order: ln[conc]= -time // second order: 1/[conc]= +time
how does the decibel scale work according to intensity? give me the equation and talk me through what happens when you get further away from the sound source.
the decibel scale works such that 10 more decibels means 10 times the sound (one bel is 10x). *70 dB is 10x the intensity of 60 dB. the equation is as follows: dB = 10 log (I/Io) // breaking that down, the Io is the smallest noise possible to be heard by the human ear. I = power (W)/ area. When you back away from a sound, you are increasing the radius, and therefore the area increases by r^2 so the same power means that it is less intense by the square of the radius. *1 m to 3m means you decrease intensity by 3^2=9. roughly a drop in 10 dB
True or False: the rate limiting step is always the slowest step
True
Explain Young’s modulus to me with the chart
young’s modulus is defined as stress/ strain. stress = strain (x) is linear (youngs modulus constant) in the elastic region until the elastic limit or yield point and then it goes into the plastic region, peaking at the ultimate strength before reaching the failure point at max strain.
what are the 2 equations for potential energy? (regular and spring)
PE= mgh // PE(max spring)= (1/2)k(delta)x^2 where this is the spring’s maximum PE. at any other point, in the movement, PE+KE= PE(max).
What are the prefixes for numbers going up?
deca= 10^1 // hecto= 10^2 // kilo= 10^3 // mega=10^6 // giga=10^9 // tera=10^12
what are the prefixes for numbers going down?
deci=10^-1 // micro= 10^-6 // nano= 10^-9 // pico= 10^-12
define electron configuration
that’s the whole mess with 2s^2 and stuff and depends on the number of electrons
explain Ohm’s law of circuits
V=IR (voltage= current*resistance)
with CAR what should you note down besides the main point and supporting arguments?
the attitude bruh. sassy quotes mean that the author doesnt believe something *“evidence”
