Acetone chlorophyll extraction - Kathryn De Abreu

Chlorophyll content of leaves can be measured in several ways. There are traditional lab methods of grinding, or immersing leaf material in particular solvents for extraction. There are also hand -held chlorophyll meters that give you chlorophyll measurements with a click of a button.
Traditional biochemical extraction methods have been the gold standard for determining chlorophyll content. There are several solvents you can use, however acetone has proven to be a popular choice.

Acetone readily dissolves the leaf tissue and is not as toxic as other solvents used. This extraction method itself needs to be done in the dark, as unbound chlorophyll is sensitive to light and degrades quickly.

First, we grind the leaf tissue in acetone using a mortar and pestle. This motion helps break up the plant cells and release the chlorophyll housed in chloroplasts. Then, we centrifuge the extract to remove any debris that would have been left behind from grinding. Any debris floating in our extract will overestimate chlorophyll content when we measure the extract later on. The supernatant contains the extracted chlorophyll that we need. Most times, the pellet is re-extracted a few times to salvage any trapped chlorophyll.

Once we extract all the chlorophyll from the leaf sample, we read the extract in a UV-Vis spectrophotometer at specific wavelengths where chlorophyll absorbs strongly in our chosen solvent (as shown). The stronger the absorption reading, the more chlorophyll present in our sample. We then calculate the actual chlorophyll content using biochemical equations tailored specifically to our extraction solvent. We express chlorophyll content as per area of leaf sample, or per dry weight of the sample.

Renewable Energy is the Future... What are the different sources of energy? What is non-renewable and renewable source of energy?
Kids had unique experience knowing about windmills and working of Dynamo... they made a working model of blowing windmill which generates electricity and led glows... #stem #stemeducation #renewableenergy #handsonlearning #experientiallearning #experimenttolearn #diy #ilovescience #skilldevelopment #youngscientist #youngengineers

Someone wants to sit next to the $8 “ladies resale” space pants I got today. Who on earth would part with these?

Have you ever wondered why certain smells trigger far off memories? This is caused by the limbic system in our brain. The limbic system is also known as the ‘emotional brain’ This part of the brain also controls stress levels, breathing, heart rate, blood pressure and memory. -

This explains exactly how essential oils can effect us in such a profound way. When inhaled, essential oils can alter our mood and help us calm down in times of stress or perk us up during sleepy times. -

Honestly, before I was skeptical about essential oils because I thought they just smell pretty. They are actually doing so much good in our body!

The fantastic @doctor_karl obliged my request for a fab selfie at our Science Week event at the Albert Hall woohoo! #fangirl #scienceweek #ilovescience #drkarl #triplej #launceston #tasmania @qvmag_official #lifegoals #science

Y’all see that tiny dot above the tree in the first picture? That’s Mars! The second picture is a screenshot of my phone using an app called SkyView. It’s free and shows you where the planets and stars are located using augmented reality. Thanks to @ms.fernandezrules for showing me this app!

The third pic is also of Mars from a different angle.

Today is my first official day of Summer break! Funny, huh? Everyone else is wrapping up summer, but my little two week break has just begun! Y’all, I AM DONE WITH PATHO!!!!!! 🍾 🎉
.
So, to celebrate I ran around the metroplex like a crazy person today! Today’s highlights:
.
🖤Took Luke to daycare
🖤Ran a million errands with Kinli
🖤Drove Kin around my hometown
🖤Barnes & Noble for new books
🖤Visited Mike at the Station
🖤Came home and worked a few hours
🖤Picked Luke up 5 mins before close
🖤Cheer Practice
🖤FINALLY HOME
.
With all the on-the-go, the drive thrus have been SUPER tempting today, but
.
1. I don’t want to waste money on junk. I’d rather spend it on 👗👠
2. It doesn’t even SOUND good. The only thing that sounds good is the convenience of it!
.
So, I blended up a peanut butter super mom shake & carried on ‘bout my business. I don’t use this as a meal replacement, please! Homegirl needs some food! I use it as a way to suppress my cravings for junk food, especially sweets, and to fuel my body with energy, vitamins, veggies, pre& probiotics, and lots of other good stuff my body needs to stay healthy!
