Momwe Njira Zamankhwala Zimagwirira Ntchito M'moyo Watsiku ndi Tsiku
Chemistry ndi kuphunzira zinthu ndi kusintha komwe kumachitika pakati pawo. Ngakhale nthawi zambiri zimaonedwa ngati gawo lovuta komanso laukadaulo, njira zamakemikolo kwenikweni ndi gawo lofunika kwambiri pa moyo wathu watsiku ndi tsiku. Kuyambira zinthu zosavuta monga kuphika chakudya mpaka njira zovuta kwambiri monga photosynthesis mu zomera, chemistry ili paliponse ndipo imachita gawo lofunika kwambiri pafupifupi mbali iliyonse ya miyoyo yathu. Nkhaniyi ikambirana za njira zosiyanasiyana zamakemikolo zomwe zimachitika tsiku ndi tsiku, kufotokoza mfundo zoyambira zomwe zili pansi pake, ndikugogomezera kufunika komvetsetsa chemistry m'miyoyo yathu.
Chemistry mu Chakudya ndi Kuphika
Kuphika ndi chimodzi mwa zitsanzo zodziwika bwino za njira zopangira mankhwala m'moyo watsiku ndi tsiku. Tikaphika chakudya, zinthu zosiyanasiyana zimachitika zomwe zimasintha mawonekedwe ndi kukoma kwa chakudya.
Maillard anachita
Maillard reaction ndi mndandanda wa mankhwala omwe amapezeka pakati pa amino acid ndi kuchepetsa shuga chakudya chikatenthedwa. Izi zimapangitsa kuti nyama yokazinga, buledi, ndi zakudya zina zikhale zofiirira komanso zovuta kuzimva. Maillard reaction ndi yofunika kwambiri pakukula kwa kukoma ndi fungo labwino muzakudya zophikidwa kapena zokazinga.
Kusungunuka kwa madzi
Kusakaniza shuga ndi njira ya mankhwala yomwe shuga imagawika m'mamolekyu ang'onoang'ono ndipo imauma ndi kusinthidwa kukhala polymer ikatenthedwa. Njirayi imapanga mtundu wa bulauni ndi kukoma kokoma muzakudya monga shuga wokazinga, anyezi okazinga, ndi msuzi wa caramel.
Kuchepa kwa Mapuloteni
Kuchepa kwa madzi ndi njira yomwe kapangidwe ka mapuloteni ka magawo atatu kamasweka chifukwa cha kutentha, pH, kapena mankhwala ena. Tikaphika mazira, mapuloteni omwe ali mu dzira loyera ndi yolk denature, amawasintha kuchoka pamadzimadzi kupita ku mkhalidwe wolimba.
Chemistry mu Thupi la Munthu
Thupi la munthu ndi malo ochitira kafukufuku wa mankhwala ovuta, komwe kumachitika zinthu zosiyanasiyana kuti munthu akhale ndi moyo komanso thanzi labwino.
Kupuma kwa Maselo
Kupuma kwa maselo ndi njira ya mankhwala yomwe maselo a thupi amasinthira shuga ndi mpweya kukhala mphamvu (ATP), carbon dioxide, ndi madzi. Njirayi imachitika mu mitochondria ndipo ndiye gwero lalikulu la mphamvu ya maselo a thupi. Machitidwe a mankhwala omwe amayambira kupuma kwa maselo ndi awa:
\[ \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{energy (ATP)} \]
Kugaya chakudya
Kugaya chakudya ndi njira zosiyanasiyana zomwe chakudya chimagawika m'mamolekyu ang'onoang'ono kuti thupi lizitha kuchigwiritsa ntchito. Ma enzyme omwe ali m'mimba amagawa chakudya, mapuloteni, ndi mafuta kukhala shuga, ma amino acid, ndi ma fatty acid. Mwachitsanzo, enzyme yotchedwa amylase yomwe ili m'malovu imagawa starch kukhala shuga wosavuta, pomwe enzyme yotchedwa protease yomwe ili m'mimba imagawa mapuloteni kukhala ma peptide ndi ma amino acid.
Photosynthesis
Kupanga kwa photosynthesis ndi njira ya mankhwala yomwe zomera zobiriwira, algae, ndi mabakiteriya ena amasintha mphamvu ya dzuwa kukhala mphamvu ya mankhwala mu mawonekedwe a shuga. Njirayi imachitika mu ma chloroplast ndipo imaphatikizapo chlorophyll ya pigment. Machitidwe a mankhwala omwe amayambira pa photosynthesis ndi awa:
\[ 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{light} \rightarrow \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \]
Kupanga kwa photosynthesis ndi njira yofunika kwambiri yomwe imapereka mpweya ku mlengalenga wa Dziko Lapansi komanso imathandizira moyo wa zamoyo pafupifupi zonse padziko lapansi.
Chemistry mu Ukhondo ndi Thanzi
Zinthu zotsukira ndi zinthu zothandiza pa thanzi ndi zitsanzo zina za momwe mankhwala amagwiritsidwira ntchito tsiku ndi tsiku.
Sopo ndi Sopo Wotsukira
Sopo ndi zotsukira ndi mankhwala omwe amagwiritsidwa ntchito kuchotsa dothi ndi mafuta pamalo. Amagwira ntchito pochepetsa mphamvu ya madzi ndi kusungunula mafuta ndi dothi, zomwe zimapangitsa kuti zikhale zosavuta kuchotsa. Sopo amapangidwa kuchokera ku mankhwala omwe amapezeka pakati pa mafuta kapena mafuta ndi maziko (saponification), pomwe zotsukira ndi zinthu zopangidwa ndi zinthu zomwe zimatha kugwira ntchito m'madzi olimba.
Mankhwala Ophera Tizilombo ndi Opha Tizilombo Toyambitsa Matenda
Mankhwala ophera tizilombo toyambitsa matenda ndi mankhwala ophera tizilombo toyambitsa matenda ndi mankhwala omwe amagwiritsidwa ntchito kupha kapena kuletsa kukula kwa tizilombo toyambitsa matenda. Zitsanzo zake ndi mowa (ethanol ndi isopropanol), hydrogen peroxide, ndi chlorine. Mankhwalawa amagwira ntchito powononga nembanemba ya maselo, kuwononga mapuloteni, kapena kusokoneza kagayidwe kachakudya ka tizilombo toyambitsa matenda.
Mankhwala osokoneza bongo
Mankhwala ndi mankhwala omwe amagwiritsidwa ntchito pochiza, kupewa, kapena kuzindikira matenda. Amagwira ntchito m'njira zosiyanasiyana, monga kuletsa ma enzyme ena, kumangirira ku ma receptor, kapena kusintha njira zama biochemical m'thupi. Chitsanzo ndi aspirin (acetylsalicylic acid), yomwe imagwira ntchito poletsa enzyme ya COX kuti ichepetse ululu ndi kutupa.
Chemistry mu Chilengedwe
Machitidwe a mankhwala nawonso amachita gawo lofunika kwambiri pakusunga ndi kusintha chilengedwe chathu.
Kuzungulira kwa Mpweya
Kayendedwe ka mpweya ndi njira yachilengedwe yomwe mpweya umayendera mumlengalenga, nyanja, nthaka, ndi zamoyo. Njira zamakemikolo monga photosynthesis, kupuma, kuwola, ndi kuyaka kwa mafuta osungidwa m'nthaka zimagwira ntchito yofunika kwambiri mu kayendedwe kameneka. Kumvetsetsa kayendedwe ka mpweya kumatithandiza kumvetsetsa kusintha kwa nyengo ndi momwe zochita za anthu zimakhudzira chilengedwe.
Kuipitsa mpweya
Kuipitsidwa kwa mpweya kumachitika chifukwa cha zinthu zosiyanasiyana zomwe zimachitika mumlengalenga. Mwachitsanzo, kuyaka kwa mafuta opangira zinthu zakale kumapanga mpweya woipa monga carbon dioxide, sulfur dioxide, ndi nitrogen oxides. Zinthu zomwe zimachitika pakati pa nitrogen oxides ndi zinthu zachilengedwe zosinthasintha pakakhala kuwala kwa dzuwa zimapangitsa kuti tropospheric ozone, yomwe ndi yovulaza thanzi la anthu.
Kuchiza Madzi
Kukonza madzi ndi njira ya mankhwala yomwe imagwiritsidwa ntchito kuchotsa zinthu zodetsa m'madzi akumwa ndi m'madzi otayira. Njirayi imaphatikizapo zochita za mankhwala monga kuuma, kuyandama, ndi kupha tizilombo toyambitsa matenda. Zitsanzo zikuphatikizapo kugwiritsa ntchito chlorine kupha mabakiteriya m'madzi akumwa ndi kugwiritsa ntchito alum (aluminium sulfate) kuti tipeze tinthu tating'onoting'ono m'madzi.
Mapeto
Machitidwe a mankhwala amagwira ntchito yofunika kwambiri pa moyo wathu watsiku ndi tsiku, zomwe zimakhudza chilichonse kuyambira chakudya ndi thanzi mpaka chilengedwe. Kumvetsetsa chemistry kumatithandiza kuyamikira ndikuwongolera njirazi, komanso kupeza njira zabwino zothetsera mavuto omwe timakumana nawo. Kuyambira machitidwe osavuta monga kuphika chakudya mpaka njira zovuta monga photosynthesis ndi kayendedwe ka kaboni, chemistry ili paliponse ndipo ndi yofunika kwambiri kuti timvetsetse dziko lotizungulira. Mwa kupitiriza kuphunzira ndikugwiritsa ntchito chemistry, titha kukonza moyo wathu ndikusunga bwino chilengedwe kwa mibadwo yamtsogolo.
