A metabolic pathway diagram for Escherichia coli showing how various nutrients-including sugars, fats, glycerol, and amino acids-are broken down into intermediates like pyruvate and acetyl-CoA, leading to the production of energy and other metabolites such as lactate, glutamate, and succinate. Arrows indicate the flow of metabolites between compounds, with key nutrient sources and products highlighted in colored boxes.

A line graph shows the electrometric titration of glycine, plotting pH on the x-axis against the volume of acid or base added on the y-axis. Red dots mark experimental data points, with the curve showing sharp pH changes near the isoelectric point at pH 6.1 and buffer regions below pH 3 and above pH 8. Explanatory text is included on the right.

Diagram showing three glycine molecules undergoing a condensation reaction to form a tripeptide chain, with two water molecules released as byproducts.
