抑胃肽
Gastric Inhibitory Peptide (GIP), human

GIP, human 是一种由42个氨基酸组成的肽类激素，是葡萄糖依赖性胰岛素分泌的促进剂和胃酸分泌的弱抑制剂。GIP, human 作为肠K细胞释放的肠促胰岛素激素，对营养摄入作出反应。

生物活性

GIP, human, a peptide hormone consisting of 42amino acids, is a stimulator of glucose-dependentinsulinsecretion and a weak inhibitor of gastric acid secretion. GIP, human acts as an incretin hormone released from intestinal K cells in response to nutrient ingestion^[1]^[2]^[3].

体外研究
(In Vitro)

Gastric Inhibitory Polypeptide (GIP) exerts various peripheral effects on adipose tissue and lipid metabolism, thereby leading to increased lipid deposition in the postprandial state^[1]. GIP, human plays a vital role in lipid metabolism and the development of obesity.

Peptide Solubility and Storage Guidelines:

1. Calculate the length of the peptide.

2. Calculate the overall charge of the entire peptide according to the following table:

	Contents	Assign value
Acidic amino acid	Asp (D), Glu (E), and the C-terminal -COOH.	-1
Basic amino acid	Arg (R), Lys (K), His (H), and the N-terminal -NH₂	+1
Neutral amino acid	Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q)	0

3. Recommended solution:

Overall charge of peptide	Details
Negative (<0)	1. Try to dissolve the peptide in water first. 2. If water fails, add NH₄OH (<50 μL). 3. If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (>0)	1. Try to dissolve the peptide in water first. 2. If water fails, try dissolving the peptide in a 10%-30% acetic acid solution. 3. If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0)	1. Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first. 2. For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.
