Arginine - structure, supplement, benefits, side effects, dosage
Jul 24, 2017 · Arginine is considered a semi-essential amino acid, meaning that while the body can produce arginine on its own, there are circumstances where dietary intake becomes important. Here are some food sources rich in arginine.
Arginine side chain interactions and the role of arginine as a …
Feb 22, 2016 · The arginine guanidinium interacts with non-polar aromatic and aliphatic side chains above and below the guanidinium plane while hydrogen bonding with polar side chains is restricted to...
Biological importance of arginine: A comprehensive review of the …
Feb 1, 2024 · Arginine shows Jekyll and Hyde behavior in several respects. It participates in protein folding via ionic and H-bonds and cation-pi interactions; the charge and hydrophobicity of its side chain make it a disorder-promoting amino acid.
2.2: Structure & Function - Amino Acids - Biology LibreTexts
Mar 21, 2024 · Arginine’s side chain contains a complex guanidinium group with a pKa of over 12, making it positively charged at cellular pH. It is coded for by six codons - CGU, CGC, CGA, CGG, AGA, and AGG. Histidine (His/H) is the only one of the proteinaceous amino acids to contain an imidazole functional group.
The Different Interactions of Lysine and Arginine Side Chains with ...
Oct 10, 2013 · The basic amino acids lysine (Lys) and arginine (Arg) play important roles in membrane protein activity, the sensing of membrane voltages, and in the actions of antimicrobial, toxin and cell-penetrating peptides. These roles are thought to stem from the strong interactions and disruptive influences of these amino acids on lipid membranes.
Arginine: Its pKa value revisited - PMC - National Center for ...
Mar 22, 2015 · The revised intrinsic p Ka value helps explains why arginine side chains in proteins are always predominantly charged, even at pH values as great as 10. The high p Ka value also reinforces the observation that arginine side chains are invariably protonated under physiological conditions of near neutral pH.
