    Pyridoxal Phosphate (PLP), an essential metabolism cofactor derived from Vitamin B6, is involved in many chemical transformations. This video summarizes the most important ones and shows how to write the curved arrow mechanisms for these transformations.

    Doing this as one of the mechanisms in 3rd biochemistry. Video is amazing, much better explanation of the steps than the prof in my class shows!

    Thank you for the clear explanation it saved my time. can you please make a video on pseudotransamination.

    I only need a quick draw of a schiff base PLP bound enzyme with Lysine in the active site. But your overall video was excellent to the point that I need. Perfect! Productive!

    At 4:41 on the third structure PLP you can see you're missing a hydrogen on the lysine-bound enzyme that the base is supposed to be taking. Cheers.

    Thank you sir for this helpful video but ı like to mention at 1:40 all of the amino acids expect Lysine , Tyrosine and Proline are participate in transamination reactions forgive me if ı'm wrong sir. Thank you again may Allah bless you :)

    At 23:14, shouldn't the N of the schiff base be deprotonated by water to complete imine formation? Also, why exactly is it favored for CO2 to deactivate rather than for the alpha carbon to be deprotonated? Wouldn't you achieve the same results with either approach?

    In The Federation of St. Kitts and Nevis, PLP also means The Peoples Labour Party if one is dealing with politics and not Organic Chemistry. Therefore, citizens and residents of The Federation of St. Kitts and Nevis - TFSKN - I am kindly encouraging you to truly CAMPAIGN hard for and VOTE overwhelmingly for ALL 8 PLP candidates on St. Kitts and for ALL 3 NRP candidates on Nevis. The names of these eleven candidates are given below: Jacqueline Bryan in St. Kitts Constituency #1 Nubian Greaux in “ “ Constituency #2 Akilah Byron Nisbett in St. Kitts Constituency #3 Kendale Liburd in “ “ Constituency #4 Staschio Williams in St. Kitts Constituency #5 Dr. Marc Williams in “ “ Constituency #6 Dr. Timothy Harris in St. Kitts Constituency #7 Andrew Talbo Bass in “ “ Constituency #8

    Dr. Patricia Bartlette in Nevis Constituency #1 Rohan Michael Isles in “ Constituency #2 Dr. Janice Daniel Hodge in Nevis Constituency #3

    How are you counting the carbons to classify it as a 5' phosphate in PLP?

    The people of St. Kitts need ALL 8 PLP candidates to win.
    The people of Nevis need ALL 3 NRP candidates to win. ALL 11 candidates in a PLP-NRP government of alliance will work immensely hard with Prime Minister Dr. the Hon. Timothy Sylvester Harris to significantly accelerate and advance individual, family, community, constituency and national development that Prime Minister Dr. Timothy Sylvester Harris has started executing and implementing to improve lives and livelihoods of Kittitians and Nevisians. Kindly VOTE for the candidates of PLP on St. Kitts and please VOTE for the candidates of NRP on Nevis.
    Fully REJECT, NEGLECT and AVOID CCM, PAM and SKNLP. Leaders of CCM, PAM and SKNLP are traitors, betrayers, mega-thievesss and misappropriaters of public funds who are hungry for power but in the court of public opinion some are guilty of breaking up the UNITY Administration that was in government in The Federation of St. Kitts and Nevis while others are guilty of putting 17 % tax on us and putting us in the hands of the IMF before Prime Minister Dr. the Hon. Timothy Harris rescued us.
    Therefore, why do the CCM, PAM and SKNLP grossly incompetent political leaders want to go back into government where they were before they selfishly abandoned the institution and voluntarily came out or where they were before they were voted out of office? Think seriously about these salient issues - my family members and friends - and be ye convinced that it is BEST for each electorate in St. Kitts to VOTE for PLP and for each electorate in Nevis to VOTE for NRP. I thank you.
