Chem4Kids: Atoms: Chemical Bonding
Chem4Kids! This tutorial introduces chemical bonding in chemistry. Other sections include matter, elements, periodic table, reactions, and biochemistry. Bonding Basics You must first learn why atoms bond together. We use a concept called "Happy Atoms."
Chem4Kids: Reactions: Overview
There are a few key points you should know about chemical reactions: 1. A chemical change must occur. You start with one molecule and turn it into another. Chemical bonds are made or broken in order to create a new molecule. One example of a chemical reaction is the rusting of a steel garbage can.

Hemoglobin Synthesis - Harvard University
The first step in heme synthesis takes place in the mitochondrion, with the condensation of succinyl CoA and glycine by ALA synthase to form 5-aminolevulic acid (ALA). This molecule is transported to the cytosol where a series of reactions produce a ring structure called coproporphyrinogen III.
The Lewis Definitions of Acids and Bases - Purdue …
In the Lewis theory, an acid is any ion or molecule that can accept a pair of nonbonding valence electrons. In the preceding section, we concluded that Al 3+ ions form bonds to six water molecules to give a complex ion. Al 3+ ( aq) + 6 H 2 O ( l ) Al (H 2 O) 63+ ( aq) This is an example of a Lewis acid-base reaction.

Iron Absorption - Harvard University
Ascorbate and citrate increase iron uptake in part by acting as weak chelators to help to solubilize the metal in the duodenum (Table 1) (Conrad and Ureit, 1993). Iron is readily transferred from these compounds into the mucosal lining cells.
