a type of food (e.g. fat, protein, carbohydrate) required in large amounts in the diet.

#2
Front (Question)

what are the functions of lipids

Back (Answer)

energy (FAs) fat storage (TGs) hormones (sterols) phospholipids (cell membrane)

#3
Front (Question)

what are the biological functions of lipids

Back (Answer)

energy structural integrity signalling

#4
Front (Question)

Lipid DRVs?

Back (Answer)

none set as not an essential nutrient

#5
Front (Question)

dietary sources of saturated fat

coconut meat cheese

#6
Front (Question)

Back (Answer)

monounsaturated • oleic • C18:1 polyunsaturated • linoleic C18:2 • linolenic C18:3

#8
Front (Question)

which tissues use fat for energy?

Back (Answer)

skeletal heart

#9
Front (Question)

functions of cholesterol

Back (Answer)

membrane fluidity bile salts steroids- androgens/ estrogen, mineralocorticoid, glucocorticoids

#10
Front (Question)

where does fatty acid metabolism occur

Back (Answer)

the mitochondria - FA to acetyl CoA by beta oxidation the cytosol - FAs are synthesised from acetyl CoA cartinine - transports long FA to the mitochondria to be oxidised to release energy

#11
Front (Question)

Front (Question)

consequences of excessive lipid intake

Back (Answer)

obesity diabetes CV disease cancer hyperlipidaemia

#13
Front (Question)

what are essential FAs?

Back (Answer)

FAs required in the diet - N-3 and N-6 cannot be synthesised by humans due to a lack of desaturase enzymes, therefore we require them from dietary sources

cell signalling inflammation immunity

#18
Front (Question)

where do eicosanoids come from?

Back (Answer)

they are synthesised from essential FAs in lipid bilayers
