C-vitamiin toimimine organismis
Vitamiin C on vajalik sidekoe normaalseks arenguks ning toimimiseks. Osaleb kollageeni ja elastiini sünteesimiseks vajalike ensüümide kofaktorina. Vajalik on hüdroksüülimises, millega ta aitab sünteesida karnitiini, sapphappeid, steroide, neuromediaatoreid (adrenaliin, serotoniin, noradreanaliin). Osaleb vitamiin E radikaalvormi viimises tagasi algvormi. Kaitseb vitamiin A, riboflaviini, tiamiini, foolhapet, pantoteenhapet ja hemoglobiini oksüdatsiooni eest. Seega on oluline antioksüdant. Pärsib veel nitroosamiinide teket seedekulglas. Osaleb raviainete biotransformatsioonis. Mõjutab raua imendumist (muudab kolmevalentse raua kahevalentseks) ja raua vabanemist transferriinist. Soodustab foolhappe koensüümi teket, mille läbi tugevndab immuunsüsteemi.
Imendumine, transport, säilitamine ja väljutamine
Seedekulglasse sattunud C-vitamiin imendub peensoolest Na sõltuva transpordiga. Aktiivtranspordina imenduvad väiksed kogused, suured kogused aga passiivdifussiooni teel. Imendumine ise on küllastav protsess. Ise manustatud 1000mg C-vitamiinist imendub 30-65%, 5000mg aga 15-20%. C-vitamiin, mis on jäänud imendumata, seob vett, seetõttu põhjustavadki suured kogused C-vitamiini kõhulahtisust. Vitamiini imendumist pärsivad liigne alkohol, palavik, rohke aspiriin, paratsetamool, kortisoon, barbituraadid, söögisooda, antihistamiinikumid. C-vitamiin on peamiselt neerupealistes, mak.

Below is an extract from a web page. Evaluate whether the page has a high educational
value and could be useful in an educational setting for teaching from primary school to
grade school levels using the additive 5-point scoring system described below. Points are
accumulated based on the satisfaction of each criterion:
- Add 1 point if the extract provides some basic information relevant to educational top-
ics, even if it includes some irrelevant or non-academic content like advertisements and
promotional material.
- Add another point if the extract addresses certain elements pertinent to education but
does not align closely with educational standards. It might mix educational content with
non-educational material, offering a superficial overview of potentially useful topics, or
presenting information in a disorganized manner and incoherent writing style.
- Award a third point if the extract is appropriate for educational use and introduces key
concepts relevant to school curricula. It is coherent though it may not be comprehensive
or could include some extraneous information. It may resemble an introductory section of
a textbook or a basic tutorial that is suitable for learning but has notable limitations like
treating concepts that are too complex for grade school students.
- Grant a fourth point if the extract highly relevant and beneficial for educational purposes
for a level not higher than grade school, exhibiting a clear and consistent writing style. It
could be similar to a chapter from a textbook or a tutorial, offering substantial educational
content, including exercises and solutions, with minimal irrelevant information, and the
concepts aren’t too advanced for grade school students. The content is coherent, focused,
and valuable for structured learning.
- Bestow a fifth point if the extract is outstanding in its educational value, perfectly suited for
teaching either at primary school or grade school. It follows detailed reasoning, the writing
style is easy to follow and offers profound and thorough insights into the subject matter,
devoid of any non-educational or complex content.
The extract: - Sidekoe normaalne areng ja funktsioneerimine.
- Neuromediaatorite süntees.

The extract provides detailed information on Vitamin C's role in the human body, its synthesis, and functions. It is coherent and relevant to educational topics, particularly biology and health. However, the language and concepts may be too complex for primary school students, and there are no exercises or solutions provided.

Educational score: 4
