MCAT practice questions
by goldstandard_mcat (Posted Sun Feb 04, 2018 11:55 pm) A cookie recipe calls for 2/3 as much sugar as flour, evenly mixed. If 2 cups of flour is used and the recipe makes 16 cookies, how much sugar is there in 6 cookies?A. 1 cupB. 1/6 cupC. 1/4 cupD. 1/2 cupCorrect answer: DThis is a conversion problem in disguise. First determine the amount of sugar in a single cookie:(2/3 cups sugar/1 cup flour)(2 cups flour/1 batch)(1 batch/16 cookies)= 1/12 cups sugar per cookieNow multiply this by 6 cookies:= 1/2 cups sugar per 6 cookies.Practice more: https://www.mcat-prep.com/mcat-practice-tests/ (Source: Med Student Guide)

Why is the anomeric carbon OH always the nucleophile in disaccharaide glycosidic linakages?
When you make a disaccharaide, its the anomeric carbon OH that is the nucleophile and the other sugar's OH that is the leaving group
(so like with a 1'4 sugar. its the carbon 4's OH, that leaves and the anomeric carbon's OH that makes the bond).
Yet when you combine glucose with an alcohol to form a glycosidic linkage, the anomeric carbon OH is now the leaving group and the alcohol the nucleophile....

I need help and miracle stories...
Hey guys,
Sugar Plum here, I try to be as positive as I can be, on this site especially; but lately I realized my situations are not working for me. I am a fifth year undergraduate, hopefully graduating this year, with not a great GPA, by the time I graduate I will probably have a 3.0, if everything goes well, and I didn't really compute my science GPA yet, because I still have a long way to go. I have had a very dysfunctional start of my college years, in which I was dealing with a...

Is having experience as a Substitute teacher good?
Hey Guys!
So, this might be a pretty dumb question, but since tutoring counts as a leadership position, does working as a substitute teacher also count? Or having a supervisor like position at an old job at a restaurant? I am asking for a "friend," lol sorry had to say it, but all jokes aside, is working as a sub, something different, in a good way?
Thank you,

Repeat. Frightening, I know! Physiologically speaking, it's also quite easy to comprehend. The personal systems regeneration process is split into two primary categories: one develops the person body system up (anabolic) and one smashes the person body system down (catabolic). The breaking-down process is required for clearing out old, cells and cellular waste material to develop room for the new. The building-up process replaces these old and cleared out cells with new ones. Want to know...

Section Bank C/P #85
I got the correct answer, but I want to make sure my reasoning was okay. I decided it couldn't be B because a disaccharide can't be reducing if both anomeric carbons are tied up in the glycosidic linkage. For the same reason, you can cross off C because it would be reducing if only one anomeric carbon was tied up in the linkage.
Both A and D are accurate in their descriptions of reducing and non reducing sugars, but I only chose A because I knew that maltose was made up of two glucose...

Reducing sugars.. hemiketal?
Aldoses are reducing sugars, because they have a hydrogen bonded to the alpha carbon.
Hemiacetals are reducing sugars because they have the same hydrogen bonded to the anomeric carbon
Ketoses can be reducing sugars if they can tautomerize (ketone <-> enediol <-> aldehyde) (will this net me wrong answers on the mcat?)
What about hemiketals? (Source: Student Doctor Network)

Has anyone tried Plexus for Blood Sugar control?
Hi y'all! I am 32 yo female and found out last June my A1C was elevated. Rather than jump right into insulin, I decided to do my best to control by being careful about the foods I eat. I was having some success (when I was perfect) but now I'm pregnant! With pregnancies 1 and 2 this meant sugars that went a little crazy. My friend sells Plexus products (they have a full selection of supplements, probiotics, etc) and a specific product called Plexus Slim. Anyone heard of it? Well, don't let the name fool you. It was developed for blood sugar regulation and then they discovered some people lost weight on it (because of BS re...
