Major nutrients Flashcards
Types of carbohydrates
monosaccharide, disaccharides and polysaccharides
simple + complex
functions of carbohydrates
provide energy
regulate blood glucose
build other molecules
storage of energy once converted to fats
simple carbohydrates
easy to break down through digestion → made up of one or two sugar molecules
simple carbohydrates examples
monosaccharides (glucose, fructose, galactose)
disaccharides (maltose, lactose, sucrose)
complex carbohydrates
harder to break down because the sugar molecules are in longer, complicated chains
made up of three or more sugars joined together
complex carbohydrates examples
polysaccharides (starches, fibres, glycogen)
mono gastric animals - role carbohydrates
provide an essential fermentative substrate to the microbiome
ruminant animals - role of carbohydrates
provide substrate for growth of ruminal microbes and production of microbial protein
chemical structure of monosaccharide
mono stands for single
single sugars
structural isomers → share the same molecular formula
C6H12O6
chemical structure of disaccharides
sugars composed of two monosaccharides joined together
simple carbohydrates
polysaccharides
many sugars
oligosaccharides
few sugars
macronutrient
generally needed in large quantities to provide energy
micronutrient
essential in small amounts for the normal process and functions
water functions
lubricant (eyes, nose, mouth)
solvent (to enable digestion of nutrients)
transport (blood)
regulator (removing heat produced by organs)
cleanser (removes toxins)
how is water lost in the body
urination
defecation
saliva
respiration
sweating
evaporation
milk
bodily fluids
