where do the amino acids come from in protein synthesis?
amino acids
in protein synthesis, a succession of trna molecules charged with appropriate amino acids are brought together with an mrna molecule and matched up by base-pairing through the anti-codons of the trna with successive codons of the mrna. the amino acids are then linked together to extend the growing protein chain, and the trnas, no longer carrying amino acids, are released. this whole complex of processes is carried out by the ribosome, formed of two main chains of rna, called ribosomal rna (rrna), and more than 50 different proteins. the ribosome latches onto the end of an mrna molecule and moves along it, capturing loaded trna molecules and joining together their amino acids to form a new protein chain.
protein biosynthesis
protein anabolism is the process by which protein are formed from amino acids. it relies on five processes: amino acid synthesis, transcription, translation, post translational modifications, and protein folding. proteins are made from amino acids. in humans, some amino acids can be synthesized using already existing intermediates. these amino acids are known as non-essential amino acids. essential amino acids require intermediates not present in the human body. these intermediates must be ingested, mostly from eating other organisms.
