Proteins ( /ˈproʊˌtiːnz/ or /ˈproʊti.ɨnz/) are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function.
A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. The sequence of amino acids in a protein is defined by the sequence of a gene, which is encoded in the genetic code. In general, the genetic code specifies 20 standard amino acids; however, in certain organisms the genetic code can include selenocysteine and—in certain archaea—pyrrolysine. Shortly after or even during synthesis, the residues in a protein are often chemically modified by posttranslational modification, which alters the physical and chemical properties, folding, stability, activity, and ultimately, the function of the proteins. Sometimes proteins have non-peptide groups attached, which can be called prosthetic groups or cofactors. Proteins can also work together to achieve a particular function, and they often associate to form stable protein complexes.
Ohhhhh
Ohhhhhhhhh
There is no short cut to a dream
But I am not afraid I'll take it all the way
I'm gunna give more than it takes
Work harder than the rest till I'm the very best
Ohh you think youv'e got it all figured out
You think ur so damn cool what's that all about
But I've got mime just watch this space
And you just wait
Hold up a mirror you should see yourself
You think your so much better than everybody else
But I've got time just watch this space
And you just wait
There's something deep inside my heart
Burns with a thousands flies
So relentess my desire
I see a future shine so bright
Beyond the finish line
I'm gunna make it mine
Ohh you think youv'e got it all figured out
You think ur so damn special what's that all about
But I've got mime yh watch this space
And you just wait
Hold up a mirror you should see yourself
You think that you wont stumble like everybody else
But I got time just watch this space
And you just wait
