Yog li, vim li cas cov piam thaj hauv dej thiaj yaj?
A Dej - soluble qab zib Yog vim li cas qabzib yaj tau yooj yim hauv dej yog vim nws muaj ntau pawg polar hydroxyl uas muaj peev xwm hydrogen-bond nrog dej molecules. Hydrogen bonds yog ib qho tseem ceeb heev rau kev sib cuam tshuam hauv lub cev uas txiav txim siab cov qauv ntawm cov molecules zoo li DNA, cov protein thiab cellulose.
Qhov thib ob, yog cov piam thaj soluble hauv cov ntshav? Txhua hom ntawv qabzib yog tsis muaj xim thiab yooj yim soluble hauv dej, acetic acid, thiab ntau lwm cov kuab tshuaj. Lawv tsuas yog sparingly soluble hauv methanol thiab ethanol.
Ua li no, ntau npaum li cas piam thaj tuaj yeem yaj hauv dej?
Qhov no ntau npaum li cas ntawm solute nyob rau hauv dej hu ua solubility thiab muaj chav nyob ntawm grams ib 100 milliliters (grams rau txhua 100 ml ntawm dej ). Solubility ntawm qab zib Nws yuav yog 180 (qhov siab tshaj plaws ntawm 180 grams). qab zib tuaj yeem yaj nyob rau hauv 100 milliliters dej ntawm chav sov).
Puas yog piam thaj soluble hauv acetone?
Nws nyob. Glucose muaj ntau hydroxyls. Polar organics nyiam acetone los yog isopropanol lossis ethanol (los yog vodka) yuav yaj nws vim tias koj tau txais hydrogen bonding uas tuav cov molecules hauv kev daws.

Cov piam thaj tseem ceeb siv los ntawm cov cell rau lub zog yog dab tsi?
Adenosine 5'-triphosphate, lossis ATP, yog cov khoom siv hluav taws xob muaj zog tshaj plaws hauv cov cell. Cov qauv no yog tsim los ntawm nitrogen puag (adenine), qab zib ribose, thiab peb pawg phosphate. Lo lus adenosine hais txog adenine ntxiv rau qab zib ribose
Dab tsi ua rau cov piam thaj hauv cov zis hauv cov dev?
Thaum cov piam thaj hauv ntshav nce mus txog qib ib, cov zis ntau dhau raug tshem tawm los ntawm ob lub raum thiab nkag mus rau cov zis. Qhov no yog vim li cas cov dev thiab cov neeg muaj ntshav qab zib mellitus muaj suab thaj hauv lawv cov zis (glucosuria) thaum lawv cov insulin qis
Koj xav tau cov txiaj ntsig dab tsi yog tias kev sim pib nrog cov piam thaj thiab IKI tov?
Cov piam thaj thiab IKI yuav txav tawm ntawm lub hnab thiab tig cov hmoov txhuv nplej siab thiab dej tov ntshav/xiav. Cov hmoov txhuv nplej tsis tuaj yeem txav mus rau sab hauv lub hnab vim tias nws cov molecules loj dhau dhau los ntawm daim nyias nyias ntawm tubing
Dab tsi yog qhov sib txawv tseem ceeb ntawm teeb meem tsom mus rau kev daws teeb meem thiab kev xav tsom mus rau kev daws?
Thaum kev ntxhov siab pom tau tias yog tswj tau, teeb meem tsom mus rau cov tswv yim daws teeb meem cuam tshuam nrog cov tsos mob ntawm kev puas siab puas ntsws, thaum nyob hauv qhov xwm txheej tsis txaus ntseeg, kev xav-tsom mus rau kev daws teeb meem cuam tshuam nrog cov tsos mob tsawg dua
Puas yog kev daws teeb meem kev kho mob tib yam li kev daws teeb meem luv luv kho?
Kev kho mob tsom mus rau kev kho mob, tseem hu ua kev daws teeb meem hais qhia luv (SFBT), yog hom kev kho mob uas muab qhov tseem ceeb tshaj ntawm kev tham txog kev daws teeb meem ntau dua (Berg, nd) Lo lus "luv luv" hauv kev kho mob luv luv yog qhov tseem ceeb
