Q

what are elcosanoids?

A

they are modified 20 carbon fatty acids with a complete or partial carbon at one end and two long carbon chain tails
they play a part in pain and inflammation and as regulators of physiological functions.
Ex: prostaglandins, thromboxanes, leukotrienes

Q

what happens when two monosaccharides undergo a dehydration reaction?

A

one will lose an OH and the other an H and then the O will be the connection between the two.
Its how you make disaccharides like sucrose, maltose, and lactose

Q

what happens why a disaccharide undergoes hydrolysis?

A

water comes in and the disaccharide is lysed. this is used to breakdown sugar for energy.
