इंग्रजी मध्ये ALKALOID म्हणजे काय?
आल्कलॉइड
अॅल्कॉलीड हे नैसर्गिकपणे रासायनिक संयुगे असलेले एक समूह आहेत ज्यात मुख्यतः मूलभूत नायट्रोजनचे अणू असतात. या गटात तटस्थ आणि अगदी कमकुवत अम्लीय गुणधर्म असलेल्या काही संबंधित संयुगे देखील समाविष्ट आहेत. समान रचना काही कृत्रिम संयुगे देखील alkaloids गुणविशेष आहेत. कार्बन, हायड्रोजन आणि नायट्रोजनच्या व्यतिरिक्त, ऍलॅलॉइडमध्ये ऑक्सिजन, सल्फर आणि क्लोरीन, ब्रोमिन आणि फॉस्फरससारख्या इतर क्वचितच इतर घटक असू शकतात. अल्क्लाइडचे उत्पादन मोठ्या प्रमाणातील जीवांनी केले जाते, ज्यात बैक्टेरिया, बुरशी, वनस्पती आणि प्राणी समाविष्ट आहेत आणि ते नैसर्गिक उत्पादनांच्या गटाचा भाग आहेत. अॅसिड-बेस्ड एक्स्टेक्शन द्वारे क्रूड अर्कांमधून अनेक अल्कलॉइड शुद्ध केले जाऊ शकतात. अनेक ऍलॅलॉइड इतर जीवांपासून विषारी असतात. त्यांना बर्याचदा औषधीय प्रभाव असतात आणि औषधी म्हणून वापरल्या जातात, मनोरंजक औषधे म्हणून किंवा स्त्रीलिंगी प्रथांमध्ये. उदाहरणे स्थानिक ऍनेस्थेटिक आणि उत्तेजक कोकेन आहेत, सायकेडेलिक psilocin, उत्तेजक कैफीन, निकोटीन, एलेजेसिस मॉर्फिन, ...
इंग्रजी शब्दकोशातील alkaloid व्याख्या
शब्दकोशात अल्कधर्मीची परिभाषा वनस्पतीतील नायट्रोजनयुक्त मूलभूत संयुगेंपैकी एक समूह आहे जी वनस्पतींमध्ये आढळते, विशेषत: पाण्यामध्ये अघुलनशील आणि शारीरिकदृष्ट्या सक्रिय असते. सामान्य उदाहरणे मॉर्फिन, स्ट्रिक्नेन, क्विनिन, निकोटीन आणि कॅफिन आहेत.
