pentose शब्द के हिंदी अर्थ का उदाहरण:

कुछ में ग्लूकोस, कुछ में ट्रेहलोस, कुछ में पेंटोस पाए जाते हैं।

८ ऐल्डोपेंटोस और १६ ऐल्डो-हेक्से की कल्पना ही प्रस्तुत नहीं की, उन्हें पृथक्‌ करके उनका रचना विन्यास भी स्पष्ट कर दिया।

८ पेंटोस ये हैं : लिक्सोस, ज़ाइलो, ऐरेबिनोस और रिबोस और इन चारों के दक्षिणभ्रामी और वामभ्रामी दो दो रूप।

एक कॉर्टिकॉस्टेरॉयड के प्रयोग का अतिरिक्त लाभ है कुछ संबंधित स्व-प्रतिरक्षित बीमारियों, जैसे कि इम्यूनोहेमोलाईटिक एनीमिया या इम्यून-मेडीयेटेड थ्रॉम्बोसाईटोपेनिया को दबाना.प्रतिरोधी स्थितियों में, न्युक्लियोसाईड औषधियों जैसे कि फ्लूडैरेबाईन, पेंटोस्टेटिन, या क्लैड्रिबाईन एकल अभिकर्ता के द्वारा उपचार सफल हो सकते हैं।

pentose's Usage Examples:

pentose sugars.

pentose phosphate pathway.

Scheibler discovered l-arabinose in 1869, and regarded it as a glucose; in 1887 Kiliani proved it to be a pentose.

hydrogen peroxide and a trace of a ferrous salt: C 4 H 9 O 4 (CH OH) CHO-->C 4 H 9 O 4 (CH OH) C02H->C4H904 CHO Hexose -> Acid -* Pentose.

CH 2 OH CH20H CH20H CH20H (CH OH) 3 -> 01 OH) 3 -> (CH OH) 3 --> (CH OH)3 CH OH CH OH CH OH CHO CHO CH:NOH CN Hexose -p Oxime -> Nitrile -> Pentose.

Glucoseoxime on warming with acetic anhydride is simultaneously acetylated and dehydrated, yielding an acetylated gluconitrile, which when warmed with ammoniacal silver nitrate loses hydrocyanic acid and is transformed into an acetyl pentose.

CH20H CH20H CH OH CH OH (CH OH) 2 -> (CH OH)2 CHO CH-OH CN Pentose -> Cyanhydrin on further oxidation gives a mannonic acid, C 5 H 8 (OH) 5 CO 2 H; this acid readily yields a lactone.

The pentose is then obtained from the acetylated compound by successive treatment with ammonia and dilute acids: CH 2 OH ([[Choh) 3 Choh Ch: Noh -)Ch20h (Choh)3 Choh Cn - Ch 2 Oh (Choh) 3 Cho]].

If the asymmetric system adjoining the COH group, which is that introduced in synthesizing the hexose from the pentose, be eliminated, the formulae at disposal for the two pentoses are CH 2 (OH) - - - COH CH 2 (OH)+-- COH.

C 4 H 9 O 4 (CH OH) C02H->C4H904 CHO Hexose -> Acid -* Pentose.

CH 2 OH CH20H CH20H CH20H (CH OH) 3 -> 01 OH) 3 -> (CH OH) 3 --> (CH OH)3 CH OH CH OH CH OH CHO CHO CH:NOH CN Hexose -p Oxime -> Nitrile -> Pentose.
