Insulin glulisine, sold under the brand name Apidra among others, is a rapid-acting modified form of medical insulin used for the treatment of diabetes.It differs from human insulin in that the amino acid asparagine at position B3 is replaced by lysine and the lysine in position B29 is replaced by glutamic acid.

The Best Amino Acid Supplements To Try Amino acid complexes are available in powder form, but many brands also offer oral capsules. Choose a product that is third-party tested to ensure the ...
[25] [26] [27] Insulin from these sources is effective in humans as it is highly similar to human insulin (three amino acid difference in bovine insulin, one amino acid difference in porcine). [27] Initially, lower preparation purity resulted in allergic reactions to the presence of non-insulin substances.
Plecanatide is a 16 amino acid peptide with the amino acid sequence: H-Asn 1-Asp 2-Glu 3-Cys 4-Glu 5-Leu 6-Cys 7-Val 8-Asn 9-Val 10-Ala 11-Cys 12-Thr 13-Gly 14-Cys 15-Leu 16-OH (one-letter sequence: NDECELCVNVACTGCL). Plecanatide is nearly structurally identical to human uroguanylin, apart from the substitution of Asp 3 with Glu 3. [13]
The amino acid sequence of animal insulins in different mammals may be similar to human insulin (insulin human INN), there is however considerable viability within vertebrate species. [16] Porcine insulin has only a single amino acid variation from the human variety, and bovine insulin varies by three amino acids.
Similar considerations apply to other amino acids with ionizable side-chains, including not only glutamate (similar to aspartate), but also cysteine, histidine, lysine, tyrosine and arginine with positive side chains. Amino acids have zero mobility in electrophoresis at their isoelectric point, although this behaviour is more usually exploited ...
Insulin degludec is a modified insulin that has one single amino acid deleted in comparison to human insulin, and is conjugated to hexadecanedioic acid via gamma-L-glutamyl spacer at the amino acid lysine at position B29. It is included on the World Health Organization's List of Essential Medicines [11] as an equivalent to insulin glargine.
Amino acid sequence of amylin with disulfide bridge and cleavage sites of insulin degrading enzyme indicated with arrows. Amylin, or islet amyloid polypeptide (IAPP), is a 37-residue peptide hormone. [5] It is co-secreted with insulin from the pancreatic β-cells in the ratio of approximately 100:1 (insulin:amylin).
