Chapter 2 - The Chemistry of Microbiology

This chapter looks at atoms, bonds, pH and organic molecules. Good review of chemistry we see in microbiology.

[@sydsydney543]

I watch your lectures and get more out of these than I do from my professors! You’re the reason I actually understand this class. Thank you!!!!

[@caelan97]

"I try to make this class as 'non-math-needed' as possible." You're my hero.

[@sm7583]

I just have to say that YOU ARE A GODSEND!!! I was having the most difficult time understanding Microbiology to the point I was considering changing my major, but came across your lectures and everything makes so much sense to me now!

[@jancunningham27]

You are awesome. You explained it very clearly. You should monetize your videos. I noticed it didnt have ads. You deserve to be paid. I subscribed in your channel. Your videos will be helpful for my studies. Thank you.

[@CB-cx8ty]

Hi, Dr., Next class is Microbiology after summer break and I can not thank you enough for your professional, informative, and educational videos!!! You will help me enter my class prepared and ready!God Bless and thank you again!!

[@gisellequiles8785]

omg! if my professor explained everything like you do, it would make the class sooooooo much easier! you are a LIFE SAVER!!! thank you!!

[@azamatibraimov3622]

Same issue with my professor

[@DNAatWork14]

I love it how you give great examples and talk fluent in subject.

[@samyajadrawi1408]

VERY APPRECIATE YOU TAKING THE TIME TO HELP US UNDERSTAND THIS COURSE BETTER!!!

[@newmans04]

Thank you so much for these lectures - your explanations and teaching style are making microbiology so much more understandable for me! I wish I could take your course in person- really, many thanks!!

[@gracejia8667]

Just finished chapter 1, sooooo helpful! I am taking a online microbio. This video makes the course so much more understandable. Thank you so much Dr. Kerschen.

[@keonyabond]

Just finished this chapter now on to 3! Thank you for the power rule and thank you for refreshing on organics bc this A&P 1 was 2 semesters ago and I am refreshed!

[@sandywong5473]

Thank you very much for sharing those valuable knowledge. It helpfulness.

[@lylynguyen6524]

Can't thank you enough for these amazing lectures

[@isabeljones1228]

Thanks a lot for your videos! Everything makes perfect sense now!

[@watupvivian4678]

Such a good explanation, and I was curious about chapter 3 sir.

[@ricardofranco-duarte346]

Chapter 3??

[@keonyabond]

I'm about to take a 5 week micro class and dudes supposed to be a hard ass! I am getting a 3 week head start and everything thing you hit on is in each chapter of my book (might be using the same one) in order! I'll be a pro when class starts! I am grateful for these videos! It's like I'm taking the class b4 the class!

[@WildlifeTshirts]

Thank u for up-loading. Tyanks, a whole bunch.

[@babydivi]

Thank you so much for these videos! My college also uses the same book. Your videos have been life-saving and grade saving as the book itself has been a cure for insomnia. I've learned so much from your lectures. I wish you were my teacher.

[@drgarabeygarabeyhope6865]

Tanuja Murjani-Moorjani may u tell me the name of the book plz.thank you

[@Daily-lw2tu]

I am now going to pass micro, my teacher is an absolute distraction. Thank God for you sir, you are an angel

[@zeynad.8116]

you're currently saving my life in Microbiology this semester, thank you!!!

[@callafrederiks8985]

Thank you for these videos. They are extremely helpful to review everything as I am learning micro from another professor. It helps me to teach myself the material, but have another voice in my head as well. Thank you so much Keep it up

[@zharbi6475]

Not taking the class but I'm getting a lot of good info from these

[@patrickbaddoo7004]

Highly educative

[@DJAbeClements]

Thank you for the video! super helpful you rock!

[@jessicaspall5941]

I am going to stop by your office to hug you. This was amazing. You have a great way of breaking everything down so it's easy to understand. I can't thank you enough for this video.

[@jessicakraemer2091]

how necessary is this to know? I was told we needed to know this for physiology but ended up not needing to know ANY of this. the only thing we needed to know was electrophysiology when learning membrane potential if you even call that chemistry.

[@Ella-ii6ze]

I understood better with you than I understood more with my professor 🙏🙌 thank you so much

[@denkeh8941]

excellent lectures!!!

[@sinanasaad1983]

WOW.. engaging :)

[@luisabohorquez878]

Omg I been a little confused in this part of Micro, thank you so much. I have a quiz coming up so you are a life saver

[@tshirtdawg8047]

Feeling like I just may be able to pull an A in my MB class. My professor is horrible, God bless her heart. She is just all over the place. This makes so much sense!

[@juanqinzhuang7828]

Thank you so much Professor

[@marcusthomas8558]

Wonderful video wish you were my biology teacher

[@withsoleil]

Hello. Dear professor,do you have any video for Vral Genomes and Diversity? Thank you.

[@chelsimartin4725]

So glad I found you. My professor made this seem like a foreign language.

[@Medicalstudent797]

all the best 😊

[@nermindecou8378]

Thank you! You made my day!

[@joycekalungi8791]

thank u , ur such a good teacher , i wish u taught me in under graduate

[@buoyaayoub1567]

can't find chapter 3, may someone help me. Thank you

[@beckyg8599]

Thank you, this has helped me so much in my microbiology class

[@Eagle_Delta]

Did you have to take notes?

[@Carolina-xz5qr]

Does anyone know which book this follows?? Can't find it anywhere!

[@WhoAmI-vr6uo]

Thank you Sir. This is kinda old but it's very helpful. My prof doesn't show up so here I am

[@madhousenmich]

Thank You!!!

[@relaxandrefocuswithmegan]

I almost fell for E all of the above at the very end of the lesson and then remembered RNA is not double stranded and it deoxyribose is DNA sugar.

[@Chris-km3bx]

thanks a lots

[@relaxandrefocuswithmegan]

Would trisaccharide equal 3 monosaccharides?

[@BalaBiologyWorld]

wow.....

[@FuckenMoonFace]

thank you Sir

[@amalmelehouse3834]

dr.. is this microbiology enough for m.b.b.s course?

[@colin200011226]

Dear Professor Edward Kerschen , What textbook do you reference in your Microbiology lectures? Thank you.

[@sabrinasegroves5751]

I also want to know.

[@relaxandrefocuswithmegan]

Chapter 1 and half of Chapter 2 I drew the diagrams for everything, but drawing is not my forte. Are there any in particular I really should draw out? I was considering the nucleic acids and the diversity of carbon structures.

[@edwardkerschen5494]

+Megan DePerro It depends on how much chemistry your instructor expects you to know. I typically don't have my students worry about the structures of monosaccharides, disaccharides, lipids etc. But if you are expected to know isomers and saturated vs unsaturated you might want to. DNA and Proteins are mostly about the base pair and amino acid sequences respectively. One nice thing about drawing the sugar and the phosphates out for DNA shows you the 5 prime 3 prime direction of both strands (anti-parallel) but I would not expect my students to have to draw it out on a test. BTW, trisaccharide would be three monosaccharides together.

[@relaxandrefocuswithmegan]

Edward Kerschen Thanks

[@alexstinecipher1129]

Is this for the openstax book "microbiology"

[@sophiehillinger7454]

does anyone have the link for chapter 3? somehow i cant find it.. thanks in advance!

[@zhenwang993]

wheres chapter three

[@K_nj]

Who is the author of the textbook that you are using?

[@gorachandadash5003]

Sir where is chapter 3 video..??

[@nelcared5634]

For a phospholipid, why is it nonpolar? Where do you find it instead of fats?

[@edwardkerschen5494]

A phospholipid is both polar and non-polar. The phosphate "head" is non-polar and attracts water while the lipid "tail" is polar and repels water so it has both parts and you find it lining cell membranes because of its perfect chemistry.

[@nelcared5634]

Thank you!

[@nelcared5634]

Wait I thought that head repeals water instead of attracting water, the tails attracts water.

[@XxAlex530xX]

NelcaRed no you got it the opposite. The head wants water the tail doesn't although this reply is quite late but oh well

[@lesliecrumpton291]

What book is he teaching out of?

[@Rohmash]

Is this for a high school microbiology class?

[@sofiabravo1994]

College

[@edwardmaximus5439]

I couldn't help but laugh when you used transformers as an example lol

[@ElPasoJoe1]

Chapter 3 seems to be missing...

[@ZVIKAGREENBERG]

Hi - minute 36:09 you wrote 6-4=4 and it should be 6-2=4

[@carolynspatacino6481]

Where is chapter 3?

[@relaxandrefocuswithmegan]

Wait how are you getting 10 million with 5 vs 13. 13-5= 8. Add a 1 and 8 zeros after it. 100,000,000.

[@edwardkerschen5494]

+Megan DePerro You are correct, I misspoke it should be 100 million not 10 million. Thanks for paying attention.

[@relaxandrefocuswithmegan]

Edward Kerschen Thanks for uploading these!

[@zrozadxz]

Is this considered Biochemistry?

[@rflores5308]

My professor is the worst. Thank you for this video!

[@agutierrez342]

Umm ch 3!

[@caribaez5711]

microbio has a bunch of chemistry, genetics, biology, and you can't memorize. :( i worked so hard and now i got C and i feel so sad. the course is 5 units and lower my gpa like three points. i want to study biology degree instead but i need a bunch. i think i would just try the nursing program but is so scary T^T i don't know what God is trying to teach me. :(

[@elexust730]

For future people there is no chapter 3 by him.

[@raimunduuu]

why is that

[@ElPasoJoe1]

Phosphorolipids -> soap?...

[@Wesley-wg2qi]

What you're saying about saturated fat isn't actually true. They don't clog arteries like we've been told for decades.

[@natashatatar2496]

hosts, boasts, toasts, posts, ghosts

[@tartanhandbag]

but remember kids, the earth is older than the universe ;)

[@Kei-Kei]

Booooo polar bonds... Share equally! 😡😆😆😆

[@KerayZ]

Enough with so many unnecessary words
