Study Notes
Lipases
- Lingual Lipase: Produced by salivary glands, initiates lipid digestion in the mouth.
- Gastric Lipase: Secreted by the stomach, continues lipid digestion.
- Pancreatic Lipase: Secreted by the pancreas into the small intestine, primarily responsible for breaking down fats into fatty acids and glycerol.
Pepsin
- Converts proteins into smaller peptides.
- Secreted by the stomach as inactive pepsinogen, activated by hydrochloric acid (HCl).
Nucleases
- Break down nucleic acids (DNA and RNA) into nucleotides in the small intestine.
- Essential for digesting genetic material from food, secreted by the pancreas.
