Sphingolipids are considered as
phospholipids if:

sugar (carbohydrate) such as glucose
All sphingolipids are phospholipids
O The polar head group contains a phosphate
group
The polar head group contains a complex
sugar (carbohydrate) containg sialic acid
Why might adding a strong reducing agent like Dithiothreitol
(DTT) help denature an extracellular protein?
O Disulfide bonds might be reduced that might be critical in stabilizing
its structure
O Disulfide bonds might be oxidized that might be critical in stabilizing
its structure
O Disulfide bonds formed inside the cytoplasm can be oxidized
O Cysteines can be reduced to form stabilizing disulfide bonds
What is the common precursor of all phospholipids and TAG?
