In organic chemistry, keto-enol tautomerism refers to a chemical equilibrium between a keto form (a ketone or an aldehyde) and an enol. The enol and keto forms are said to be tautomers of each other. The interconversion of the two forms involves the movement of a proton and the shifting of bonding electrons; hence, the isomerism qualifies as tautomerism.A compound containing a carbonyl group (C=O) is normally in rapid equilibrium with an enol tautomer, which contains a pair of doubly bonded carbon atoms adjacent to a hydroxyl (−OH) group, C=C-OH. The keto form predominates at equilibrium for most ketones. Nonetheless, the enol form is important for some reactions. Furthermore, the deprotonated intermediate in the interconversion of the two forms, referred to as an enolate anion, is important...

40 days and 40 nights
Today is start of Lent. If you know me well enough, you know how much I value these upcoming weeks and days. It gives me a sense of pride and honor to do what I think is unthinkable. Most of the time, I ask myself why am I doing this? But, I always end up with one answer – I will do this because I need to do it. Maybe, it really runs into my veins to be a stupid person as I can be. I wanted to move on but I always ended up being a failure - anyways, it’s not time to sentimental so change topic.
Tonight, I read a passage from the book (given by Father Ollie) about the word “metanoia which means a change of one’s heart and mind”. It is nice to hear that – change of one’s heart and mind. As a person, I may say that I am not as bad as people think of me but I am good neither. I am just an ordinary...

cold housewarming
we cleaned the house early in the morning. john, jay and i were busy preparing until we realized that the snow is heavily falling. oh my! today should have been our housewarming party...after few minutes, i went to the nearest supermarket and bought some more beef for the pot roast. snow still falling from heaven and entering my delicate eyes.time came and no sign of visitors – not even a text message or a call. they are just late – i know that – and they are. ana arrived first followed by the rest of the people. it was so much fun! we played rock band, cranium and talked about different things.so f...

office
hhaayy...nandito pa din ako sa office. as usual, kayod kalabaw pa rin dahil sa mas pinili kong maging kalabaw kaysa maging isang araro. =) .gusto ko lang ibahagi sa inyo ang nararamdaman kong kasiyahan ngayon...a. masaya ako kasi napagtagumpayan ko na naman ang isang araw na walang tinatapakan na tao.b. masaya ako dahil sa masarap yung kinain ko kaninang bourbon chicken.c. masaya ako kasi napigilan kong magbigkas ng masakit na salita sa taong kinakainisan ko.d. masaya ako dahil sa naayos na yung problema ko sa insurance ko.hhaayy...sana ganito lagi kaayos ang lahat ng bag...

sweet home alabama
one of the activities that I really enjoy here in chicago is playing the guitar hero with jay and john. i love it! it gives me a sense of fulfillment for my frustration of playing a guitar.few weeks ago, there was this song in one of our gigs that is - for me - so hard. the song is sweet home alabama. i tried so hard but i failed. but today, i was able to finish it! i was so happy for i was able to finish the song...yaaahhhoooo!!! i getting better and better each day. =)...
valentine's day
hhhaaayyy....ngayon lang ang pinakamalugkot kong valentine's day. mag-hapon ako sa bahay, nanuod lang na tv at naharap na naman sa isang matinding rejection.wala naman sanang problema, pero sana di na lang ako pina-asa. mahirap pala yun? hahaha. pero rest assured na alam ko na ang kailangan kong gawin.dami pang problema...di ko alam kung naintindihan ang kalagayan ko. akala siguro isa talaga akong mayamang tao.ang ending, masaya ako? wala naman akong magagawa kundi ngumiti na lang at yapusin kung ano ang problema. isa itong blessing para sa akin....
araw ng mga puso
eksaktong 12.28 na nang umaga - 02.14.2009 na. ito pa rin ako, sa tingin ko ay nag-iisa na lamang na gising. tulog na si jay. si john naman mukhang tahimik na sa kwarto - di ko alam kung naka-earphone habang nag-lalaro ng ps3 - at ako, kakaligo ko lang, hehehe.mahigit isang buwan na kami dito sa chicago. parang bahay ni kuya. kaya lang, sa halip na 100 araw lang, 1 taon. at siyempre walang ma-tatanggal. pero the emosyon ay ganun pa rin. makikilala mo talaga ang mga tao kapag kasama mo na sila sa iisang bahay lamang. wala naman akong masasabing masama sa kanilang dalawa dahil napag-titiyagaan nila ako.pero bakit nga pala ako nag-susulat ngayon ay dahil sa araw ngayon ng mga puso. sabi ng isa kong ka-klase sa kolehiyo, ang araw daw ng mga puso ay isa lamang komersyalismo. negatibo ang pananaw...

kahit siguro sandali lamang.
kahit siguro ano ang gawin ko wala akong magagawa kundi ang asamin na makita siya.kahit siguro sandali lamang.kahit siguro paano ko man ibaling ang tingin ko sa ibang tao, pilit pa ring pumapaalimbuyo ang kaniyang mukha sa aking isipan.kahit siguro sandali lamang.kahit siguro sino man ang pilit kong ipalit ay walang makakapantay sa kanya.kahit siguro sandali lamang.kahit siguro kailanman ay mananatili na lang siyang parte ng buhay ko. di na siya maaalis.kahit siguro sandali lamang.pero alam kong kailangang lumaban sa agos ng isipan. kailangan di manumbalik ang dating pag-hahanap, pag-nanasang makapiling at pagsusumayong makadaupang palad na mu...
experimentation
i love doing experiments in laboratories. hehe. i miss the mixes, titrations, gravimetric analysis, filtration...and now, i have a new laboratory - it is the kitchen. i am starting to enjoy mixing and cooking. i should say that i am learning.....
