Protein

Proteins are organic compounds made of amino acids arranged in a linear chain and joined together by peptide bonds between the carboxyl and amino groups of adjacent amino acid Residue ....

Biochemistry

Biochemistry is the study of the chemistry processes in living organisms. It deals with the structure and function of cellular components such as proteins, carbohydrates, lipids, nucleic acids and other biomolecules....
 processes responsible for the synthesis of proteins
Protein synthesis

Protein synthesis is the creation of proteins using DNA and RNA. Proteins can often be synthesized directly from genes by Translation mRNA. When a protein is harmful and needs to be available on short notice or in large quantities, a protein precursor is produced....

Amino acid synthesis

For the non-biological synthesis of amino acids see: Strecker amino acid synthesisAmino acid synthesis is the set of biochemical processes by which the various amino acids are produced from other compounds....

Protein catabolism

Protein catabolism is the breakdown of proteins into amino acids and simple derivative compounds, for transport into the cell through the plasma membrane and ultimately for the polymerisation into new proteins via the use of ribonucleic acids and ribosomes....

ain article: Protein biosynthesis
Protein biosynthesis

Protein synthesis is the process in which cell build proteins. The term is sometimes used to refer only to protein translation but more often it refers to a multi-step process, beginning with amino acid synthesis and transcription which are then used for translation ....

Protein biosynthesis relies on four processes;

Protein anabolism is the process by which protein are from amino acids (aka anabolic amino acid synthesis).

Protein catabolism is the process by which proteins are broken down to their amino acids.
