https://en.wikipedia.org/wiki/ChlorophyllChlorophyll (also chlorophyl) is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, khloros ("pale green") and φύλλον, phyllon ("leaf"). Chlorophyll is essential in photosynthesis,

https://simple.wikipedia.org/wiki/ChlorophyllXem thêm trên simple.wikipedia.orgChlorophyll is necessary for photosynthesis, which allows plants to obtain energy from light. Chlorophyll molecules are arranged in and around the membranes of chloroplasts. It serves two main functions.

Chlorophyll a - Wikipedia
https://en.wikipedia.org/wiki/Chlorophyll_aChlorophyll a is a specific form of chlorophyll used in oxygenic photosynthesis. It absorbs most energy from wavelengthsof violet-blue and orange-red light, and it is a poor absorber of green and near-green portions of the spectrum. Chlorophyll does not reflect light but chlorophyll-containing tissues appear green because green light, diffusively reflected by structures like cell walls, be…

Chlorofyl – Wikipedie
https://cs.wikipedia.org/wiki/Chlorofyl- Biosyntéza začíná připojením glutamátu na tRNA. Vzniklá glutamyl-tRNA může být použita jak pro syntézu proteinů, tak dále při syntéze chlorofylů. Glutamyl-tRNA se přeměňuje na glutamyl-1-semialdehyd, ten na kyselinu 5-aminolevulovou a ta v porfobilinogen. Porfobilinogen je už cyklický a obsahuje pyrrolové jádro. Čtyři porfobilinogeny formují protoporfyrin IX, který obsahuje porfyri…
