Not to be confused with Retinal. Retinol, also known as Vitamin A1, is a vitamin found in food and used as a dietary supplement. As a supplement it is used to treat and prevent vitamin A deficiency, especially that which is resulting in xerophthalmia.
Desmosomes are anchoring junctions â mechanical couplings scattered like rivets along the sides of adjacent cells to prevent their separation. On the cytoplasmic face of each plasma membrane is a thickening called a plaque.
Tight junctions hold cells together in a sheet, restricting the movement of substances between the cells. Tight junctions are found in cells that line the digestive tract. 2--Adherens junction. Adherens junctions are anchoring junctions that use integrin to hold cells together by anchoring to the cells' actin networks.Adherens junctions, as other anchoring junctions are found in tissues that are subject to mechanical stress such as muscle and epithelium.esmosomes are anchoring junctions that use cadherin to hold cells together by anchoring to the cells' actin networks, or for more stable cell-to-cell connections by anchoring to the cells' intermediate fibers.
