Glycolysis - Basic introduction to the reactions and pathway of glycolysis.
The Main Metabolic Pathways - Map of main metabolic pathways, such as glycolysis, the citric acid cycle,
fatty acid synthesis and oxidation, amino acid metabolism and the urea cycle,
with chemical figures.
Metabolic Pathways of Biochemistry - Graphical representation of metabolic pathways that are crucial to human
metabolism, including 2-D and 3-D depictions.
Kimball's
Biology Pages - Mini-essays on a number of biological topics with a lot
of cell biology. (Beginner's Level)
Cellular
Respiration - Basic information on cellular respiration (mitochondria,
the citric acid cycle, the respiratory chain, the chemiosmotic hypothesis
for ATP synthesis, ATP).
Metabolism - Basic introduction to metabolism (catabolism, anabolism and nutrition).
The Medical Biochemistry
Page - An excellent biochemistry tutorial with information on a broad
range of biochemical pathways. (Michael W. King, Indiana University School of Medicine)
The WIT Project - "The WIT
Project attempts to produce metabolic reconstructions for sequenced (or partially
sequenced) genomes." (Argonne National Laboratory)
Metabolic Pathway Databases (Data Collections on Metabolic Pathways)
BioCyc - "BioCyc is a collection
of Pathway/Genome Databases. Each database in the BioCyc collection describes
the genome and metabolic pathways of a single organism, with the exception
of the MetaCyc database, which is a reference source on metabolic pathways
from many organisms."
Biological Biochemical Image Database - Images of biological pathways, macromolecular structures, gene families
and cellular relationships. (National Institute of Aging)
Kyoto Encyclopedia of Genes and
Genomes (KEGG) - Graphical and hypertext-based information on biochemical
pathways, including metabolic and regulatory pathways (for instance, cell
cycle and growth factor signaling).
Metabolic Database - Database listing metabolic intermediates and their relationships.
Photosynthesis
Center - Resources in photosynthesis, basic and advanced information,
links to conference, journal and lab sites. (Arizona State University)
The Photosynthetic
Process - An introduction to photosynthesis that "focuses on the
structure of the photosynthetic machinery and the reactions essential for
transforming light energy into chemical energy." (John Whitmarsh and
Govind Jee, University of Illinois, Urbana-Champaign)
