| Description | Lisosome word in die sitoplasma van alle eukariotiese selle behalwe die volwasse rooibloedsel gevind. Die matriks van die organel word van die omringende sitoplasma deur 'n trilaminêre eenheidsmembraan geskei en bevat 'n verskeidenheid suur hidrolitiese ensieme. Morfologies word primêre (mint gevorm vanaf die Golgi-kompleks) en sekondêre lisosome onderskei. Laasgenoemde ontstaan na versmelting van 'n vakuool met 'n primêre lisosoom en is ultrastruktireel besonder heterogeen weens die groot verskeidenheid substrate (makromolekule) wat in die matriks van die organel geïnkorporeer kan word. Die suur hidrolases van lisosome kan in vyf groepe verdeel word, naamlik fosfatases , nukleases, polisakkaried- en glikosaminoglikaan (GAG)-liidrolases, proteases en lipases. Lysosomes are found in the cytoplasm of all eucaryotic cells except mature red blood cells. The matrix of the organelle is separated from the surrounding cytoplasm by a trilaminar unit membrane and contains a variety of acid hydrolytic enzymes. Morphologically primary (recently formed from the Golgi-complex) are distinguished from secondary lysosomes. The latter type is formed after fusion of a vacuole with a primary lysosome and is ultrastructurally extremely heterogeneous due to the large variety of substrates (macro molecules ) incorporated in the matrix of the organelle. The acid hydrolases of lysosomes are divided into the following five groups: phosphatases, nucleases, polysaccharide- and glycosaminoglycans (GAG)-liydrolases, proteases and lipases. | |
