three amino acids

. Both those dipeptides have 3 free functional groups which further react with relevant groups of other amino acids forming tri, tetra, penta peptides and so on. Both -CO and -NH groups of peptide bonds are polar. They are involved in hydrogen bond formation. In a prot..

- ) accepts a proton and gets converted to carboxyl substituent (- COOH) while in basic solution the ammonium substituent (+NH 3 ) changes to amino group (-NH 2 ) by losing a proton. In acidic solution, an amino acid exists as a positive io..

Proteins are the polymers of amino acids. Therefore, amino acids form the raw material for protein synthesis. The proteins found in living organisms need about 20 amino acids as building blocks or monomers. These are available in the cyto..

Amino acids are compounds containing carbon, hydrogen, oxygen and nitrogen. They serve mainly as monomers (building blocks) of proteins. An amino acid is represented by a general empirical formula R.CH.NH 2 . COOH. Each amino acid has at l..

Excess amino acids or proteins in higher animals are broken down into ammonia which are converted into less toxic substances like urea and uric acid in the liver. But in lower animals like molluscs and echinoderms the excess amino acid gets removed..

Amino acids are the building blocks of proteins. There are 300 amino acids that occur in nature. Among these only 20 are known as standard amino acids that commonly occur in proteins. Amino acids contain two functional ..

The amino acids that are to be supplied through diet are called as essential amino acids. They cannot be produced by the body. The essential amino acids are arginine, valine, histidine, isoleucine, leucine, lysine, methionine, phenylalani..

Amino acids are synthesised by two main processes: 1) Reductive animation In this process, ammonia reacts with a -ketoglutaric acid to form glutamic acid..

are those that are not synthesized by the body and are needed in the diet. Methionine, threonine, tryptophan, valine, isoleucine, leucine and phenylalanine are the essential amino acids..
