molecules made from smaller building blocks called amino acids. If there are less than 10 amino acids the molecule is called a peptide; if 10 to 100 a polypeptide;...

of multiple monomer units called amino acid, which have many different functional groups. More than 500 amino acids exist in nature, but the proteins...

different amino acids can differ in size and structure, as well as electric charge (acidic or basic), which influences the solubility of the amino acids in water...

biological processes and amino acids are the building blocks of it. A large proportion of cells, muscles and tissue is made up of amino acids, meaning they carry...

or a D enantiomer. The stereochemistry of an L-amino acid. All amino acids in nature are L-amino acids, except for bacterial cell walls and the odd w:en:cone...

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...

catalyzing amino acids (other enzymes are also discussed catalyzing carbohydrates, fatty acids, nucleic acid, and urea cycle.) Amino acid metabolism disorders...

majority of non-common amino acids. There are typically presented as twenty to twenty two common amino acids. The most common amino acids are Glycine, Alanine...

amino acids (to identify amino acids). To demonstrate separation of amino acids by paper chromatography To use chromatography to identify amino acids...

standard amino acids differ from one another. In the simplest of the acids, glycine, the R consists of a single hydrogen atom. Other amino acids have more...

of this process is that eventually the amino acids will collectively become racemic: each particular amino acid will have one chirality or another, but...

Overview To synthesize amino acids, there must be a source of nitrogen that is in a form that can be easily used. Various microorganisms reduce inert...

of amino acids play a key role in cellular physiology my controlling signalling pathways and gene expression. GCN2 (general control of Amino Acids biosynthesis...

that turns the α-amino group from an α-amino acid to an α-ketoacid. These enzymes catalyze α-amino groups from a variety of amino acids to α-keto-glutarate...

bonds to activated amino acids and transfers them to the ribosomes. Once at the ribosome, an initiator tRNA binds the amino acid to the ribosome to start...

side-chains of proteogenic amino acids are quite varied: they range from a single hydrogen atom (as for glycine, the simplest amino acid) to the indole heterocycle...

called amino acids. There are a total of 20 amino acids. Proteins can be made from a lots of different combinations and number of amino acids. This creates...

specific amino acid attaches itself to the next codon at the A site of the larger subunit. These two amino acids (methionine and the amino acid on X) now...

units called amino acids. There are 20 different amino acids and they are connected by a peptide bond between the carboxyl group and the amino group in a...

other standard amino acids, thus the (R) instead of (S). Zwitterions The amine and carboxylic acid functional groups found in amino acids allow it to have...
