Document Summary
The process of breaking food into (1) smaller pieces for enzymes, and (2) smaller molecules for absorption. Ingest food: mechanically digest into smaller pieces, those smaller pieces then get chemically digested into small nutrient molecules, those nutrient molecules get absorbed through the gut, undigested material is defecated. Equal amounts of c and o, with more h (e. g. , c6h12o6); 55% complex carbohydrates per day. Mo n o sa c c h a r i d e s. Building blocks of carbohydrates ( monomers ) with 3 to 9 carbons e. g. , glucose, ribose, galactose, fructose. Common types: pentose sugars (5 c) ribose and deoxyribose, hexose sugars (6 c) glucose, galactose, mannose, fructose. Two subtypes: aldoses double bond at the end of the carbon chain ribose, glucose, galactose, ketoses double bond at the center of the carbon chain ribulose, fructose. D i sa c c h a r i d e s.
