Amino acid basics

Amino acids are biologically important organic compounds composed of amine (-NH2) and carboxylic acid (-COOH) functional groups, along with a side-chain specific to each amino acid. 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. They include the 23 proteinogenic (“protein-building”) amino acids, which combine into peptide chains (“polypeptides”) to form the building-blocks of a vast array of proteins. Twenty of the proteinogenic amino acids are encoded directly by triplet codons in the genetic code and are known as “standard” amino acids. Many important proteinogenic and non-proteinogenic amino acids also play critical non-protein roles within the body. For example, in the human brain, glutamate (standard glutamic acid) and gamma-amino-butyric acid (“GABA”, non-standard gamma-amino acid) are, respectively, the main excitatory and inhibitory neurotransmitters; hydroxyproline (a major component of the connective tissue collagen) is synthesised from proline; the standard amino acid glycine is used to synthesise porphyrins used in red blood cells; and the non-standard carnitine is used in lipid transport. Nine proteinogenic amino acids are called “essential” for humans because they cannot be created from other compounds by the human body and, so, must be taken in as food. Others may be conditionally essential for certain ages or medical conditions. Essential amino acids may also differ between species. Because of their biological significance, amino acids are important in nutrition and are commonly used in nutritional supplements, fertilizers, and food technology.

Protein-building amino acids:

  • Alanine
  • Cysteine
  • Aspartic acid
  • Glutamic acid
  • Phenylalanine
  • Glycine
  • Histidine
  • Isoleucine
  • Lysine
  • Leucine
  • Methionine
  • Asparagine
  • Pyrrolysine
  • Proline
  • Glutamine
  • Arginine
  • Serine
  • Threonine
  • Selenocysteine
  • Valine
  • Tryptophan
  • Tyrosine

Essential amino acids:

An essential amino acid or indispensable amino acid is an amino acid that cannot be synthesized de novo (from scratch) by the organism being considered, and therefore must be supplied in its diet. The nine amino acids humans cannot synthesize are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine. Six amino acids are considered conditionally essential in the human diet, meaning their synthesis can be limited under special pathophysiological conditions, such as prematurity in the infant or individuals in severe catabolic distress. These six are arginine, cysteine, glycine, glutamine, proline and tyrosine. Five amino acids are dispensable in humans, meaning they can be synthesized in the body. These five are alanine, aspartic acid, asparagine, glutamic acid and serine.

  • Histidine
  • Isoleucine
  • Leucine
  • Lysine
  • Methionine
  • Phenylalanine
  • Threonine
  • Tryptophan
  • Valine

  1. There are a couple of easy-to-do dishes that supply a lot
    of health insurance fat loss benefits. We are very mindful that losing several extra few pounds have lots of advantages
    about the long term. Also, aren’t getting confused that hunger is
    always thirst.

  2. Here are some tips from the truth about abs review.

    They are extremely ineffective yet people make
    an effort to do hundred of them, for what.

  3. Much of the is dependent upon the kind of foods on your table,
    when you are eating them as well as the amount and type of exercise you happen to be doing.

    Everyone fantasizes that shedding pounds will transform their entire life.
    Every time I have attemptedto go “all in” simultaneously, I wind up losing,
    whether in Vegas or trying to steer clear of my neighbors BBQ.

  4. Hello there! Would you mind if I share your blog with my
    twitter group? There’s a lot of people that I think would really enjoy your content.
    Please let me know. Thanks

  5. At first don’t get worried about calorie counting or weighing the meat instead get the foods you like and look for healthy
    alternatives. Try wearing a pedometer and measuring the amount of
    steps you adopt each day, planning to accumulate more from a
    current average. A great way to start paying more awareness of your
    diet plan would be to start keeping a regular food diary.

  6. Once one’s body gets rid in the long staying waste

    I say to you, I certainly get annoyed whilst people consider worries that they just don’t recognise about.
    You controlled to hit the nail upon the top and also outlined out
    the entire thing without having side-effects , folks could take a signal.
