What is biomolecules explain with example

 

✅ What is a Biomolecule?

Biomolecules are naturally occurring organic molecules that are essential for life. They are the building blocks of living organisms and are involved in all biological processes.

🔹 Definition:

Biomolecules are chemical compounds found in living organisms that are mainly made up of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), and sulfur (S).

🔹 Major Types of Biomolecules:

  1. Carbohydrates
    🔸 Function: Provide energy
    🔸 Example: Glucose, Starch

  2. Proteins
    🔸 Function: Build and repair tissues, enzymes, hormones
    🔸 Example: Hemoglobin, Insulin

  3. Lipids (Fats and Oils)
    🔸 Function: Store energy, make cell membranes
    🔸 Example: Cholesterol, Triglycerides

  4. Nucleic Acids
    🔸 Function: Store genetic information
    🔸 Example: DNA (Deoxyribonucleic acid), RNA (Ribonucleic acid)

🔹 Other Important Biomolecules:

  • Vitamins – Help in metabolic processes
  • Hormones – Regulate body functions
  • Enzymes – Speed up biochemical reactions

🔹 Examples in Daily Life:

Biomolecule Type Example Found In
Carbohydrate Glucose Fruits, rice, bread
Protein Albumin Eggs, meat, milk
Lipid Butter (fat) Dairy, oils, nuts
Nucleic Acid DNA, RNA Present in all living cells

Let me know if you want this in Hindi, or need Class 12 notes on this topic.

What is means of isolated gaseous atom

  💨 Isolated Gaseous Atom – Meaning: An isolated gaseous atom means: 👉 A single atom of an element 👉 In the gaseous state (not bonded to any other atom or molecule) 👉 That is completely free from external forces (like other atoms or molecules nearby) 🧪 In Simple Words: An isolated gaseous atom is a lone atom in the gas phase, existing independently , just like: A single He atom (Helium) floating alone in space Not forming a molecule like O₂ or H₂ Not in solid or liquid form 🔍 Why Important in Chemistry? It is a reference state used in: Ionization energy Electron affinity Enthalpy calculations Bond dissociation energies These properties are usually measured for an isolated gaseous atom because: There's no interference from other atoms. It gives the purest form of an element's energy or behavior. 🧠 Example: If we say: "The ionization energy of an isolated gaseous hydrogen atom is 1312 kJ/mol" It means: the energy required...

What is electron gain enthalpy // what is electron gain enthalpy in Chemistry class 11

  ⚛️ Electron Gain Enthalpy (Δ eg H) Electron gain enthalpy is the amount of energy released or absorbed when an electron is added to an isolated gaseous atom to form a negative ion . 🔬 Definition: "Electron gain enthalpy is the enthalpy change when one mole of electrons is added to one mole of isolated gaseous atoms." 📘 General Reaction: X_{(g)} + e^- \rightarrow X^-_{(g)} \quad \Delta_{eg}H = isolated gaseous atom = anion formed = added electron = electron gain enthalpy 🔥 Key Points: Negative electron gain enthalpy : Energy is released (exothermic). Most nonmetals show this behavior. Example: Chlorine Cl_{(g)} + e^- \rightarrow Cl^-_{(g)} \quad \Delta_{eg}H = -349 \text{ kJ/mol} Positive electron gain enthalpy : Energy is absorbed (endothermic). Some elements (like noble gases or N) show this. Example: Nitrogen , Neon 📊 Trends in Periodic Table: Across a Period (→) : Electron gain enthalpy becomes more negative (more energy...

बफर विलयन (Buffer Solution) क्या है? – रसायन विज्ञान में

 बफर विलयन (Buffer Solution) क्या है? – रसायन विज्ञान में परिभाषा: बफर विलयन एक ऐसा विलयन होता है जो अपने pH मान में अत्यधिक परिवर्तन नहीं होने देता, जब उसमें थोड़ी मात्रा में अम्ल (Acid) या क्षार (Base) मिलाया जाए। --- ✅ बफर विलयन के प्रकार: 1. अम्लीय बफर (Acidic Buffer): इसमें एक कमज़ोर अम्ल और उसके लवण (जो किसी मजबूत क्षार से बना हो) का मिश्रण होता है। उदाहरण: एसीटिक अम्ल (CH₃COOH) + सोडियम एसीटेट (CH₃COONa) 2. क्षारीय बफर (Basic Buffer): इसमें एक कमज़ोर क्षार और उसके लवण (जो किसी मजबूत अम्ल से बना हो) का मिश्रण होता है। उदाहरण: अमोनियम हाइड्रॉक्साइड (NH₄OH) + अमोनियम क्लोराइड (NH₄Cl) --- ⚙️ यह कैसे काम करता है? जब बफर विलयन में थोड़ा अम्ल डाला जाता है, तो यह अतिरिक्त H⁺ आयनों को न्यूट्रल कर देता है। जब थोड़ा क्षार (OH⁻ आयन) डाला जाता है, तो यह उसे भी न्यूट्रल कर देता है। इस प्रकार, pH मान लगभग स्थिर रहता है। --- 🧪 बफर विलयन का उपयोग: मानव शरीर में (जैसे – रक्त का pH लगभग 7.4 होता है, जो बफर के कारण स्थिर रहता है) रासायनिक प्रयोगों में, जहाँ एक निश्चित pH बनाए रखना आवश्यक होता ...
