What are the 2 roles of acids within the digestive system?

Assists in the digestion of food (by dissolving chemical bonds within food molecules) Activates stomach proteases (e.g. pepsin is activated when pepsinogen is proteolytically cleaved in acid conditions) Prevents pathogenic infection (stomach acids destroy microorganisms in ingested food)

The neutralization is described by the equation: HCl + NaHCO3 → NaCl + H2CO.

What time of day is stomach acid the highest?

Sleep and circadian rhythm may influence acid secretion and gastric motor activity. Acid secretion is highly variable from night to night, yet peaks in a circadian fashion between 10 pm and 2 am, suggesting a circadian component ( Figure 1).
