phospholipid
phospholipid Biochem. (fɒsfəʊˈlɪpɪd) Also -ide (now rare). [f. phospho- + lipid.] Any compound whose products of hydrolysis include fatty acids, phosphoric acid, and (with some writers) a nitrogen base; esp. one that is an ester of glycerol phosphate; in recent use applied more widely to any lipid c...

Phospholipid:diacylglycerol acyltransferase
In enzymology, a phospholipid:diacylglycerol acyltransferase () is an enzyme that catalyzes the chemical reaction phospholipid + 1,2-diacylglycerol lysophospholipid The systematic name of this enzyme class is phospholipid:1,2-diacyl-sn-glycerol O-acyltransferase. This enzyme is also called PDAT. wikipedia.org

Phospholipid scramblase
In humans, phospholipid scramblases (PLSCRs) constitute a family of five homologous proteins that are named as hPLSCR1–hPLSCR5. Scramblases, flippases, and floppases are three different types of enzymatic groups of phospholipid transportation enzymes. wikipedia.org

Is carbohydrate an important part of phospholipid? My professor tells us that carbohydrate is an important part of phospholipid, but phospholipid is composed of Choline, Phosphate, Glycerol and two Fattyacid, and I do...
Your thinking is correct based on typical carbohydrates, but glycerol, the backbone of the phospholipid, is a 3-carbon carbohydrate that is usually derived A carbohydrate definitely is an important structural part of the phospholipid, but your instructor probably should have been more clear in describing why

Phospholipid Bilayer structural reversal What would happen if the phospholipids in the phospholipid bi-layer were reversed, the fatty acid tails now facing outwards and the phosphate heads facing inwards? I'm assuming...
This would have quite dramatic consequences. The layers are ordered in the way they are, because of their polarity. In the way they are ordered, the hydrophobic tails are inside and directed towards each other, the hydrophilic heads are orientated to the outside and inside. Since both sides of the m...

Phospholipid movement in cell membranes What causes phospholipids to flow so quickly in cell membranes? In Biology by Cambell et al. they state that a phospholipids can travel up to 2 micrometers per second. Is that a...
There must be charge considerations in the movement of molecules in the lipid membrane. There is also a consideration that some species of phospholipids will migrate to portions of the membrane with sharper or smoother curvature. Waves of electrical potential can propagate along a lipid bilayer as w...

Phospholipid-translocating ATPase
In enzymology, a phospholipid-translocating ATPase () is an enzyme that catalyzes the chemical reaction ATP + H2O + phospholipid in ADP + phosphate + phospholipid out The 3 substrates of this enzyme are ATP, H2O, and phospholipid, whereas its 3 products are ADP, phosphate, and phospholipid. wikipedia.org

Structure of Cell Are cells spheres or ovals/circles bound by phospholipidbilayer? If they are spherical how are we able to see the nucleus through the phospholipid bilayer under a microscope?
Not exactly. That is a stereotype of cells. Muscle cells are not round nor oval, but rather elongated rods. If you were to look up epithelia cells, you can quickly see that cells are grouped based on their physical characteristics; simple (round/oval & single layer), columnar, and cuboidal to name a...

Phospholipid: Definition, Structure, Function | Biology Dictionary
Phospholipid Definition. A phospholipid is a type of lipid molecule that is the main component of the cell membrane. Lipids are molecules that include fats, waxes, and some vitamins, among others. Each phospholipid is made up of two fatty acids, a phosphate group, and a glycerol molecule. When many phospholipids line up, they form a double ...

Phospholipid | Cell Membrane, Lipid Bilayer & Fatty Acids
Jan 30, 2024phospholipid, any member of a large class of fatlike, phosphorus-containing substances that play important structural and metabolic roles in living cells.The phospholipids, with the sphingolipids, the glycolipids, and the lipoproteins, are called complex lipids, as distinguished from the simple lipids (fats and waxes) and from other fat-soluble cell components, mostly isoprenoids and steroids.

Why do mitochondria have a phospholipid bilayer? So, a thought came up and I couldn't find all that much info online, so I thought I'd ask some professionals here! _The endosymbiont theory_ states that: mitochondria ...
I think the question is based on a false premise: > _Poster:_ Now, mitochondria are said to have been archaea, right? > > _Me:_ Wrong, I’m afraid. The closest bacterial relation of mitochondria is _Rickettsia_ , an alpha-Proteobacterium (see Lang _et al._ for a review). _Rickettsia_ is a eubacterium...
