What is the length of a triglycerides? How are glycerol and fatty acids “connected” to make a triglyceride?

Biology
1 answer:
Ostrovityanka [42]3 years ago

Every fatty acids has a long hydrocarbon chain (with even amounts of carbons, usually 16 or 18) and a carboxyl group.

glycerol is a 3-carbon molecule with 3 -OH groups.

fatty accids and glycerol can be connected by single or double bonds, depending on if the fatty acid is saturated or unsaturated.

when a lipid forms, the -COOH functional groups of 3 fatty acids react with -OH groups of glycerol.

this leaves 16, 18, or 20 carbons, making a triglyceride 16, 18, or 20 carbons long.

hope this helps!

The saturation of hemoglobin is __________% at the arterial PO2 of 95 mmHg, and is __________% at the venous PO2 of 40 mmHg.
ra1l [238]

The saturation of hemoglobin is <u>100% </u>at the arterial PO₂ of 95 mmg and is <u>75% </u>at the venous PO₂ of 40 mmHg

<h3>Saturation of Hemoglobin</h3>

The saturation of hemoglobin at the arterial PO₂ is 100 percent due to the constant supply of oxygen taken in from the environment. while at the venous PO₂ the hemoglobin is 75% due to the limited supply of oxygen.

Hence we can conclude that The saturation of hemoglobin is <u>100% </u>at the arterial PO₂ of 95 mmg and is <u>75% </u>at the venous PO₂ of 40 mmHg.

in summer, what happens to the hurricane’s temperature, category, and speed as it travels across a body of water and then land?
IRISSAK [1]

I think it starts to get slower as soon as it starts traveling because then hurricanes wouldnt be as bad and would be long, and it could possible get worse as it travels across the water because it could be sucking up water so then it would get bigger and worse. The tempertaure will get colder because it will then start to pour and cause destruction and make it windy and very chilly.
