PY - 2014 T2 - Integrative Medical Biochemistry Examination and Board Review AB - High-Yield TermsSphingolipid: a class of lipid composed of a core of the long-chain amino alcohol, sphingosine, to which is attached a polar head group (such as a sugar) and a fatty acid via N-acylationCeramide: a class of lipid composed of a sphingosine core and a single fatty acid but no polar head group as for sphingolipidsSpingomyelins: a class of sphingolipid that contains phosphocholine as the polar head group and are, therefore, also a class of phospholipidSaposin: a family (A, B, C, and D) of small glycoprotein activators of lysosomal hydrolases that are all derived from a single precursor, prosaposinHexosaminidases: dimeric enzymes composed of 2 subunits, either the α-subunit (encoded by the HEXA gene) and/or the β-subunit (encoded by the HEXB gene); various isoforms of β-hexosaminidase result from the combination of α- and β−subunitsLysosomal storage disease: any of a large family of disorder resulting from defects in lysosomal hydrolases resulting in accumulation of incompletely degraded complex lipids, particularly of the sphingolipid familyCherry-red spot: a finding describing the appearance of a small circular deep red choroid shape in the fovea centralis (fundus) of the eye in a variety of lipid storage diseases SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/25 UR - accesspharmacy.mhmedical.com/content.aspx?aid=1122103864 ER -
