 		Science Demonstration on the Enzyme Bromelain
Have you even tried to make Jell-O with fresh pineapple in it? If so, you've been disappointed. Here's why, with a classroom demonstration for teaching about enzymes.
New Research Provides Insight to Eye Condition
The eye is a delicate ocular instrument. Age-related macular degeneration is the most common cause of blindness in the elderly population, but it could be prevented.
Metabolism and Valence Electron Energy
ATP is produced in cellular metabolism by using the high energy of valence electrons around carbon and hydrogen.
A Simple Explanation of Adenosine Triphosphate
All cells need energy to function. Adenosine triphosphate, created using food or sunlight, is the molecule that cells use to store that energy for future use.
Structure of an Atom
Atoms are the basic building blocks of matter. They form the molecules that are involved in the processes of living systems.
Cell Metabolism is a Defining Feature of Life
What is cell metabolism? Obtaining food and converting it to energy is one of the features of life. This happens within animals, plants and individual cells.
Cell Membrane
Water is highly organized by contact with the double layer of membrane lipids. Hydrophilic phosphates of the phospholipids hydrogen bond into the water surface layers.
What Is Surface Tension?
Water at the surface is frozen in a stretched sheet of optimally bonded molecules, as molecules shake into the minimal energy configuration.
Hydrophobic, Hydrophilic and Hydrogen Bonds
Molecules that form hydrogen bonds with water are hydrophilic and those that can't are hydrophobic.
Hydrogen Bonds Form Biological Structures
Cell membranes, ribosomes, protein complexes and biological macromoles such as nucleic acids and proteins are held together by hydrogen bonds.
Cell Metabolism and Energy Basics for Everyone
Energy abounds in organic molecules and the key, as in mining ore, is to extract and process it. Simple bacterial cells and highly complex organisms do this well.
Reaction Specificity of Enzymes
Enzymes bind to particular molecules, because the protein secondary structure rigidly displays amino acid functional groups that make multiple bonds with the molecules.
Proteins and Amino Acids
Proteins are a major component of all of our cells. Amino acids are the building blocks of protein. Amino acids can be grouped according to their chemical behavior.
Angiotensin II Signaling Pathways
Tyrosine kinase signaling is but one path activated by angiotensin II to regulate fluid balance, cell growth, and more.
Oxygen and Dietary Antioxidants
Why do we breathe oxygen? Oxygen is necessary for life, and the human brain can only survive a few minutes without oxygen. So why the great interest in antioxidants?
LSD – Psychedelic Hallucinogen
The history of a drug with remarkable potential which was banned through misuse by "hippies."
DNA: The Information Molecule
The history and structure of the most important molecule in living organisms, Deoxyribonucleic Acid.
Automated Peptide Synthesis
The discovery in 1963 by Bruce Merrifield of a way to automatically synthesise polypeptides and protiens accurately and without loss of yield.
What Is Cellular Metabolism?
We hear the word used all the time, read diet books on how to boost ours and lament its slowing as we age. But what exactly is metabolism?
What Is an Enzyme Catalyst?
A cell's ability to carry out essential chemical reactions separates the animate from inanimate. Without these biological catalysts, life itself would not be possible.
What Is the Nucleotide ATP?
Adenosine triphosphate is a power-packed nucleotide that cells of our body just can't live without. Here's a clear summary of what ATP is, how it works and how it's made.
Enzyme Inhibition
Read about the goals of Ribonuclease A,TPCK and enzyme inhibition in modern protein chemistry.
Cholesterol Chemistry
A chemical description of an infamous but important chemical which is ever-present in dietary advice.
The Chemistry of Fat
Describing the importance of different kinds of fats in the human body. Explaining terms like Saturated, Mono-unsaturated and Poly-unsaturated, cis and trans.
Proteins
Protein is one of the nutrients we must consume to stay healthy, but what is it and what does it do in the human body?
