what are protiens composed of?

Answer 1

amino acids; this giant molecule mainly constructed from carbon, oxygen, nitrogen and hydrogen atoms.

Answer 2

The building block of protein is the amino acids.the amino acids are the compunds made up of carbon ,nitrogen and hydreogen.
The amino acids contain a central carbon atomto which an amino group , a carboxyl group and an R(alky group i.e., side chains) are attached.
there are 20 amino acids which made proteins and thes are called structural amino acids.

Answer 3

Proteins are polymers built from 20 different L-alpha-amino acids. Proteins are assembled from amino acids using information present in genes. Genes are transcribed into RNA, RNA is then subject to post-transcriptional modification and control, resulting in a mature mRNA that undergoes translation into a protein. mRNA is translated by ribosomes that match the three-base codons of the mRNA to the three-base anti-codons of the appropriate tRNA. The enzyme aminoacyl tRNA synthetase catalyzes the addition of the correct amino acid to their tRNAs.

The two ends of the amino acid chain are referred to as the carboxy terminus (C-terminus) and the amino terminus (N-terminus) based on the nature of the functional group on each extremity.

Answer 4

they are made by amino acids. there are 64 in nature (plus some synthetic but you don't need to know this). these are redundant in quantity because each species has its own set of aa. they then get assembled in a linear chain by the ribosomes. once it is assembled it goes through transformations that are secondary structure, tertiary structure and quaternary structure. at the end the protein is fully shaped and functional

Answer 5

amino acids

Answer 6

amino acids, nitrogen base, etc

Answer 7

I dont know.. I think amino acids....

Answer 8

they are made of amino acids.

Answer 9

so easyyyy....AMINO ACIDS
