Amino acids are biologically important organic compounds containing amine (-NH2) and carboxylic acid (-COOH) functional groups, usually along with a side-chain specific to each amino acid. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen, though other elements are found in the side-chains of certain amino acids. About 500 amino acids are known and can be classified in many ways. They can be classified according to the core structural functional groups' locations as alpha- (α-), beta- (β-), gamma- (γ-) or delta- (δ-) amino acids; other categories relate to polarity, pH level, and side-chain group type (aliphatic, acyclic, aromatic, containing hydroxyl or sulfur, etc.). In the form of proteins, amino acids comprise the second-largest component (water is the largest) of human muscles, cells and other tissues. Outside proteins, amino acids perform critical roles in processes such as neurotransmitter transport and biosynthesis.
Khan Academy is a non-profit educational organization created in 2006 by educator Salman Khan with the aim of providing a free, world-class education for anyone, anywhere. The organization produces short lectures in the form of YouTube videos. In addition to micro lectures, the organization's website features practice exercises and tools for educators. All resources are available for free to anyone around the world. The main language of the website is English, but the content is also available in other languages.
The founder of the organization, Salman Khan, was born in New Orleans, Louisiana, United States to immigrant parents from Bangladesh and India. After earning three degrees from the Massachusetts Institute of Technology (a BS in mathematics, a BS in electrical engineering and computer science, and an MEng in electrical engineering and computer science), he pursued an MBA from Harvard Business School.
In late 2004, Khan began tutoring his cousin Nadia who needed help with math using Yahoo!'s Doodle notepad.When other relatives and friends sought similar help, he decided that it would be more practical to distribute the tutorials on YouTube. The videos' popularity and the testimonials of appreciative students prompted Khan to quit his job in finance as a hedge fund analyst at Connective Capital Management in 2009, and focus on the tutorials (then released under the moniker "Khan Academy") full-time.

Introduction to Amino Acids
Q&A; - Why do you take so many amino acids?
Understanding amino acids and their role in the Central Dogma of Molecular Biology (how the information in DNA eventually gets expressed as chains of amino acids). Thinking about the amino and carboxyl groups and how amino acids are typically found as zwitterions at physiological pH. How amino acid side chains can impact protein structure.

I'm taking biochem this summer and so realized that I'm going to have to memorize the amino acids - OUCH!! But when I tried to look up mnemonics, there weren't really any good ones, so I tried to come up with some myself! Hope some of the people who watch this will have an easier time memorizing - GOOD LUCK!!! :-D Please like and comment!
It's time to start learning about all the monomers that make up large biomolecules, and the first one we will look at is the amino acid. These make up proteins, which is most of what you are, so this is pretty important stuff!

In this video, you'll learn about the general structure of amino acids, which include an amine group, a carboxylic acid group, and a unique side chain (R-group) attached to the alpha carbon. In addition, we'll explore where amino acids fit in terms of biological metabolism. By Tracy Kovach. . Created by Tracy Kim Kovach.

In this video we share a method of remembering the structures of the 20 commonly occurring amino acids through tricks involving their single-letter abbreviations. We do not cover any amino acid chemistry in this video (like chemical properties), just the structures. We hope you find it helpful, and if you find any errors or have any suggestions for improvement, please let us know!

Listen my friend for I shall bestow the secret of
happiness upon you:
no greater joy than the excitement of a wild snowball
fight,
no greater cosiness than the warmth of an open fire,
no greater achievement than forced genetic stride
So to fulfil this holy trinity, to inseparably unite
them
into oneness, there is, logically, only one way:
creation of a
nuclear winter
wonderland, pure bliss
condensed into crystalline white with just a hint of a
green tinge.
Just let your inner eye
gaze into this marvellous glance:
Children running (around), whooping, flinging three
snowballs at once.
not everyone
may recognize
that we’re in store for a future so bright
Such a dear sight,
who needs a
Christmas carol
when one can have a fission parol?
Just press that cute little button, such a lovely shade
of red, and of you go, the dream comes true, in the end
Snow gently caressing the earth, the dream of every
little boy
Snow gently caressing the earth, the children radiate
with joy
not everyone
may recognize
that we’re in store for a future so bright
We should
Ask ourselves
With open eyes
isn't the quest for bliss worth a few million
sacrificed?
we will behold the genesis of a paradise:
the nuclear winter wonderland shall arise
Snow gently caressing the earth,
the dream of every girl and boy
Snow gently caressing the earth,
