Gastric lipase Gastric lipase who makes it? function?

Chief cells

Begins digestion of lipids (minor role)

Hydrochloric acid (HCl) who makes it? function?

Parietal cells

Lowers stomach pH, activates pepsinogen, kills microbes

Intrinsic factor who makes it? function?

For digesting vitamin B12

amylase who makes it? function?

Made by pancrease to Further breaks down carbohydratesm, acts in the duodenum

nuclease who makes it? function?

Made by pancrease and Digestes nucleic acid

protease who makes it? function?

Made by pancreas to digest peptides into amino acids

Enterokinase purpose?

Activates trypsinogen into trypsin which then activates other proteases for protein digestion.

Trypsinogen?

Inactive protease, activated to trypsin by enterokinase

Bile

Duodenum via common bile duct

Emulsifies fats to aid lipase activity
