Problem Set - Small Molecules (Campbell Chapters 2 and 3) 1. What are the SPONCH elements and what is common among these elements that make them suitable for life? State the four most frequently occurring of the SPONCH elements. Which of the SPONCH elements is found in each of the large biomolecules (carbohydrates‚ proteins‚ lipids‚ nucleic acids). The SPONCH elements are Sulfur‚ Phosphorus‚ Oxygen‚ Nitrogen‚ Carbon and Hydrogen. These are the five key elements that compose living

important to understand and examine the water molecule in order to ascertain how it brought about Earth’s thriving ecosystem and how important it is for us today. Water is a strong solvent‚ it’s a very unique molecule that can breaks and reforms constantly. Each water molecule consists acid What is acid rain? Acid rain is the term for pollution caused ... of one oxygen atom and two hydrogen atoms. The oxygen atom also called the "apex of the water molecule" bears a slight electronegative charge while

cell and between cytoplasm and the external environment. The cytoplasm and extracellular environment of the cell are aqueous solutions. They are composed of water‚ which is the solvent‚ or dissolving agent‚ and numerous organic and inorganic molecules‚ which are the solutes‚ or dissolved substances. Organelle membranes and the plasma membrane are selectively permeable‚ allowing water to freely pass through but regulating the movement of solutes. The cell actively moves some dissolved substances

Biology‚ Biological Molecules Revision Notes Distinguish between monomers and polymers: Monomers- Identical small molecules. Polymers- Chainlike molecules formed from the linking together of many similar. Distinguish between monosaccharides‚ disaccharides‚ and polysaccharides: Monosaccharides- Simple sugars; sugar molecules may be enantiomers due due to the spatial arrangement of parts around asymmetric carbons; raw material for synthesis of other organic molecules. Disaccharides- Two

Alexander Shulgin‚ world renowned biochemist is quoted asking “...but the important question is‚ what isn’t DMT in?”. Its described well by Dr. Rick Strassman‚ the only scientist given permission to study it in the last 40 years as; “The Spirit Molecule”. Many believe this substance‚ which flows through every human’s veins may be a link between the mundane world and spiritual world. DMT use‚ albeit nothing like the pure substance that is used today has been traced back to 8th century Chili
