Biosynthesis (also called biogenesis or anabolism) is a multi-step, enzyme-catalyzed process where substrates are converted into more complex products in living organisms. In biosynthesis, simple compounds are modified, converted into other compounds, or joined together to form macromolecules. This process often consists of metabolic pathways. Some of these biosynthetic pathways are located within a single cellular organelle, while others involve enzymes that are located within multiple cellular organelles. Examples of these biosynthetic pathways include the production of lipid membrane components and nucleotides.
The prerequisite elements for biosynthesis include: precursor compounds, chemical energy (e.g. ATP), and catalytic enzymes which may require coenzymes (e.g.NADH, NADPH). These elements create monomers, the building blocks for macromolecules. Some important biological macromolecules include: proteins, which are composed of amino acid monomers joined via peptide bonds, and DNA molecules, which are composed of nucleotides joined via phosphodiester bonds.

In this video I go through the entire process of fatty acid biosynthesis pointing out the important enzymes and intermediates. I try to color code the reactions so you can follow the carbons from the original molecules to the final product.

Translation, the assembly of proteins by ribosomes, is an essential part of the biosynthetic pathway, along with generation of messenger RNA (mRNA), aminoacylation of transfer RNA (tRNA), co-translational transport, and post-translational modification. Protein biosynthesis is strictly regulated at multiple steps, and error-checking mechanisms are in place. The cistron DNA is transcribed into a variety of RNA intermediates. The last version is used as a template in synthesis of a po...
Brief overview of amino acid synthesis and context within the cell
This lecture explains about the mechanism of purine biosynthesis pathway. The process of both purine salvage pathway and de novo pathway is explained with this video lecture. Purine synthesis is required to make nucleic acid structures like DNA and RNA in cell that will be required as genetic material in cell. So continue to watch this biochemistry lecture to understand the purine salvage pathway and purine synthesis de novo pathway.

Plenary lecture by Sarah O'Connor, John Innes Centre entitled 'Chemistry and biology of plant alkaloid biosynthesis'. This lecture took place during the New Phytologist next generation scientists conference, held at the John Innes Centre in July 2014 (http://www.newphytologist.org/nextgensci).
