Glutamic acid is a polar, negatively charged amino acid due to its carboxylic acid side chain, making it hydrophilic and often involved in enzyme active sites or neurotransmission. In contrast, valine is a non-polar, hydrophobic amino acid characterized by its branched-chain structure, which makes it more suitable for stabilizing protein structures. These differences in polarity and charge influence their roles in protein folding and interactions within biological systems.
Valine in place of glutamic acid is cause of S.C.anemia .
The disease sickle cell anaemia occurs due to a mutation. This causes the amino acid glutamic acid (which is hydrophilic) in haemoglobin to be replaced by valine (which is hydrophobic).
Alphabetically, the first 10 amino acids are alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, and hydroxyproline. The other ten are isoleucine, leucine, lysine methionine, phenylalanine, proline, pyroglutamatic, serine, threonine, tryptophan, tyrosine, and valine.
In sickle cell anemia, glutamic acid is replaced by valine due to a single base change in the gene that codes for hemoglobin. This substitution causes the hemoglobin protein to form abnormal sickle-shaped red blood cells, leading to the symptoms of the disease.
valine
Valine is a branched-chain amino acid that is non-polar and hydrophobic, while glutamic acid is a polar, negatively charged amino acid that is hydrophilic. Valine is involved in protein synthesis and energy production, while glutamic acid plays a role in neurotransmission and protein synthesis.

glutamic acid is replaced by valine in the beta chain
The disease sickle cell anaemia occurs due to a mutation. This causes the amino acid glutamic acid (which is hydrophilic) in haemoglobin to be replaced by valine (which is hydrophobic).
Substitution of Val for Glu in the 6th amino acid may disrupt protein structure and function, as these amino acids have different properties. Valine is hydrophobic and bulky, while glutamic acid is hydrophilic and negatively charged. This change could impact protein folding, stability, and interactions with other molecules.

the 20 standard amino acids that build up a protein can be classified as 1)Non polar, 2) Uncharged polar and 3)Charged polar. the names are as follows:1) Non-Polar: Glycine, alanine, valine, leucine, isoleucine, methionine, proline, phenylalanie, tryptophan.2) Uncharged polar: Serine, threonine, cytoseine, tyrosine, aspargine, glutamine.3) Charged polar: Aspartate, glutamate, histidine, lysine and arginine.
