Amino/peptide/protein/GIVE ME A BREAK!

Apr 05, 2005 21:04

Ok, Ali has brought this sad, sad statement to the forefront of my mind once again so here is my rant:

You may have seen the commercial for Olay Daily Regenerating Serum in which they say:
"Regenerist Daily Regenerating Serum uses a concentrated form of an exclusive Amino-Peptide Complex"

Here is the deal. Amino acids and peptides cannot form a complex becuase peptides ARE MADE OF amino acids! Not to mention, I have never seen or heard of amino acids being abbreviated into "aminos". And all of this aggravates me because I spent forever n biochemistry memorizing the 20 essential amino acids and their structures and to hear this!

So the following is your science lesson for the day because it is shit like this that makes people fall into teaps set by companies that don't think the public is smart enough to decipher the truth from their scienctific jargon.....

Peptides are chains of amino acid residues with remarkable biological functions, ranging from hormonal regulation to antibiotic activities. -- http://www.americanpeptidesociety.com/pages/about.asp

peptide n. (PEP-tide)
Small piece of protein consisting of a linear molecule made up of two or more amino acids (the building blocks of proteins) linked by peptide bonds -- http://www.antigenics.com/glossary/definition.phtml?word=113

amino acid
(Science: biochemistry) A class of organic molecules that containing an amino group and can combine in linear arrays to form proteins in living organisms. -- http://www.biology-online.org/term.php?do=search&search=amino+acid

peptide
Any compound consisting of two or more amino acids. -- http://www.biology-online.org/term.php?do=search&search=peptide

Proteins Are Made From Small Building Blocks
Proteins are like long necklaces with differently shaped beads. Each "bead" is a small molecule called an amino acid. There are 20 standard amino acids, each with its own shape, size, and properties.

Proteins contain from 50 to 5,000 amino acids hooked end-to-end in many combinations. Each protein has its own sequence of amino acids.

These amino acid chains do not remain straight and orderly. They twist and buckle, folding in upon themselves, the knobs of some amino acids nestling into grooves in others.

Now, I don't want to have to do this again anymore than you want to read it. Do I make myself clear?
