  2. Glutathione - Wikipedia

    en.wikipedia.org/wiki/Glutathione

    While all animal cells are capable of synthesizing glutathione, glutathione synthesis in the liver has been shown to be essential. GCLC knockout mice die within a month of birth due to the absence of hepatic GSH synthesis. [4] [5] The unusual gamma amide linkage in glutathione protects it from hydrolysis by peptidases. [6]

    en.wikipedia.org/wiki/Aminopeptidase

    For instance, Aminopeptidase N (AP-N) is particularly abundant in the brush border membranes of the kidney, the small intestine, and the placenta, and is also found in the liver. [4] AP-N is involved in the final digestion of peptides generated from the hydrolysis (cleaving) of proteins by gastric and pancreatic proteases .

    The main liver cells are called hepatocytes; however, there are other cells that can be observed in a liver sample such as Kupffer cells (macrophages). [2] The liver is the biggest gland of the body. It has a wide variety of functions that range from the destruction of old blood cells to the control of the whole metabolism of macromolecules . [ 3 ]

    GHK-Cu (glycyl-L-histidyl-L-lysine) is a human copper binding peptide with wound healing and skin remodeling activity, which is used in anti-aging cosmetics and more commonly referred to as copper peptide; Lactotripeptides (Ile-Pro-Pro and Val-Pro-Pro) found in milk products, act as ACE inhibitors

  9. Hepatic stellate cell - Wikipedia

    en.wikipedia.org/wiki/Hepatic_stellate_cell

    Quiescent stellate cells represent 5-8% of the total number of liver cells. [4] Each cell has several long cytoplasmic protrusions that extend from the cell body and wrap around the sinusoids. [5] The lipid droplets in the cell body store vitamin A as retinyl palmitate. [6] Hepatic stellate cells store 50–80% of the body's vitamin A. [6]
