IF YOU WANNA PASS THEN YOU GOTTA KNOW THE PATHWAYS!
So like most BioChem students I tried memorizing by putting my notes to music
...Then I got carried away...
Welcome to Moof University! My name is Mahfoud, and I recently graduated from UC Riverside. I've made these videos to help students with introductory biochemistry. The videos are loosely structured around what I learned from the elementary biochemistry course I took on campus (BCH 100) at UC Riverside. I hope, however, that any and all individuals who want to learn basic biochemistry find these videos helpful.
In addition, if you are a student at UC Riverside taking BCH 100 (or a student at a school near UC Riverside), and you find these videos helpful, but still want more help, please feel free to email me at MoofUniversity@gmail.com if you are interested in my tutoring services.

Protein biosynthesis is the process by which biological cells generate new proteins; it is balanced by the loss of cellular proteins via degradation or export. 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 polypeptide chain. Protein will often be synthesized directly from genes by translating mRNA. When a protein must be available on short notice or in large quantities, a protein precursor is produced. A proprotein is an inactive protein containing one or more inhibitory peptides that can be activated when the inhibitory sequence is removed by proteolysis during posttranslational modification. A preprotein is a form that contains a signal sequence (an N-terminal signal peptide) that specifies its insertion into or through membranes, i.e., targets them for secretion.[1] The signal peptide is cleaved off in the endoplasmic reticulum.[1] Preproproteins have both sequences (inhibitory and signal) still present.
In protein synthesis, a succession of tRNA molecules charged with appropriate amino acids are brought together with an mRNA molecule and matched up by base-pairing through the anti-codons of the tRNA with successive codons of the mRNA. The amino acids are then linked together to extend the growing protein chain, and the tRNAs, no longer carrying amino acids, are released. This whole complex of processes is carried out by the ribosome, formed of two main chains of RNA, called ribosomal RNA (rRNA), and more than 50 different proteins. The ribosome latches onto the end of an mRNA molecule and moves along it, capturing loaded tRNA molecules and joining together their amino acids to form a new protein chain.[2] Source of the article published in description is Wikipedia.

- Breakdown of Purines produces Uric acid (a nitrogenous waste)
- High levels of Uric acid can cause Gout
- Uric Acid levels are increased when:
1. Cell turnover is high (some kinds of cancer)
2. Glucose is being overly-shunted into the Pentose Phosphate Shunt
The nomenclature of Nucleotides changes depending on whether a sugar is attached and if a phosphate is attached.
Two pathways for biosynthesis:
De-Novo (From scratch) – Used in growth
Salvage pathway (Recycling) – Used to maintain
THF is used for nucleotide synthesis by acting as a carbon carrier
Ribose-5-Phosphate from Pentose Phosphate shunt is converted to PRPP, which is converted to phosphoribosylamine
Phosphoribosylamine is converted to IMP
IMP can go down two pathways, making either ATP or GTP
Pyrimidines are formed from Aspartate and Carbomoyl phosphate (same as urea cycle)
- Then PRPP is added (after the fact)
Carbomoyl Phosphate and Aspartate combine to form the Pyrimidine ring
- The pyrimidine ring is added to PRPP to form Orotidylate,
- UMP, UTP are formed from Orotidylate
- CTP is formed from UTP

Biosynthesis (also called biogenesis) is an enzyme-catalyzed process in cells of living organisms by which substrates are converted to more complex products. The biosynthesis process often consists of several enzymatic steps in which the product of one step is used as substrate in the following step. Examples for such multi-step biosynthetic pathways are those for the production of amino acids, fatty acids, and natural products. Biosynthesis plays a major role in all cells, and many dedicated metabolic routes combined constitute general metabolism.
The prerequisites for biosynthesis are precursor compounds, chemical energy (such as in the form ATP), and catalytic enzymes, which may require reduction equivalents (e.g., in the form of NADH, NADPH).
Commonly known complex products of biosynthesis include proteins, vitamins, and antibiotics. Most organic compounds in living organisms are built in biosynthetic pathways.

Two pathways for biosynthesis:
De-Novo (From scratch) – Used in growth
Salvage pathway (Recycling) – Used to maintain
THF is used for nucleotide synthesis by acting as a carbon carrier
Ribose-5-Phosphate from Pentose Phosphate shunt is converted to PRPP, which is converted to phosphoribosylamine
Phosphoribosylamine is converted to IMP
IMP can go down two pathways, making either ATP or GTP
Pyrimidines are formed from Aspartate and Carbomoyl phosphate (same as urea cycle)
- Then PRPP is added (after the fact)
Carbomoyl Phosphate and Aspartate combine to form the Pyrimidine ring
- The pyrimidine ring is added to PRPP to form Orotidylate,
- UMP, UTP are formed from Orotidylate
- CTP is formed from UTP

- Breakdown of Purines produces Uric acid (a nitrogenous waste)
- High levels of Uric acid can cause Gout
- Uric Acid levels are increased when:
1. Cell turnover is high (some kinds of cancer)
2. Glucose is being overly-shunted into the Pentose Phosphate Shunt

This video describes the constitution of peptidoglycan layer and the value of their presence onto the surface of microorganisms.
Peptidoglycan, often referred to as murein, is a polymer such as sugars and amino acids that varieties a mesh-like layer outside the plasma membrane of bacteria (but not Archaea), forming the cellphone wall. The sugar factor consists of alternating residues of β-(1,4) linked N-acetylglucosamine and N-acetylmuramic acid. Connected to the N-acetylmuramic acid is a peptide chain of three to five amino acids. The peptide chain can be move-linked to the peptide chain of one other strand forming the 3D mesh-like layer.[1] Some Archaea have a similar layer of pseudopeptidoglycan or pseudomurein, the place the sugar residues are β-(1,three) linked N-acetylglucosamine and N-acetyltalosaminuronic acid. For this reason the mobile wall of Archaea is insensitive to lysozyme.[2] Peptidoglycan serves a structural function within the bacterial phone wall, giving structural strength, as well as counteracting the osmotic stress of the cytoplasm. A original misconception is that peptidoglycan offers the cellphone its shape; nevertheless, whereas peptidoglycan helps keep the structural force of the cellphone, it is truly the MreB protein that allows mobilephone form[citation needed].[3][4] Peptidoglycan can be involved in binary fission for the period of bacterial telephone replica.

A conventional metabolic pathway leads to a specific product. In stark contrast, there are diversity-generating metabolic pathways that naturally produce different chemicals, sometimes of great diversity. We demonstrate that for one such pathway, tru, each ensuing metabolic step is slower, in parallel with the increasing potential chemical divergence generated as... ....
Molecular interactions between AT and ACP [Biochemistry]>
Edit PNAS 01 Feb 2016
Acyltransferases (ATs) are key determinants of building block specificity in polyketide biosynthesis. Despite the importance of protein–protein interactions between AT and acyl carrier protein (ACP) during the acyltransfer reaction, the mechanism of ACP recognition by AT is not understood in detail. Herein, we report the crystal structure of AT VinK,... ....
