Other amino acids avoid water and are called hydrophobic, such as isoleucine, phenylalanine, and valine. The amino acid cysteine has a chemically reactive side chain that can form bonds with ...

An unstable haemoglobin causing inclusion-body anaemia is described. Its amino-acid substitution is in the haem pocket of the α chain, homologous in position to that in Haemoglobin Hammersmith ...

There are 20 amino acids that make up proteins and all have the same basic structure, differing only in the R-group or side chain they have. Amino acids are in an equilibrium between two acids with ...

The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Non-Essential Amino Acids: These amino acids can be synthesized ...

The researchers found that 57 metabolites exhibited significant changes in TD, mainly involving amino acids and lipids. These changes mostly affected the phenylalanine, tyrosine, and tryptophan ...
